Wellman Doctor of Philosophy Department of Anthropology June 2021 Title: Marine Mammals before Extirpation: Using Archaeology to Understand Native American Use of Sea Otters and Whales in Oregon prior to European Contact Tribal ancestors living on the Oregon coast prior to European contact were skilled fisher-hunter-gatherers residing in a rich environment, home to diverse marine mammals. Euro-Americans over-exploited these marine mammals and drove some species to near extinction. Some marine mammal populations rebounded while others, such as the locally extinct Oregon sea otter, never recovered. Threats from hunting are past, but marine mammals on the Northwest Coast today face new challenges, and sea otters and cetaceans are foci of conservation efforts. Despite the interest these taxa enjoy in the present, little systematic study of their use by and relationship with precontact peoples in Oregon has occurred, and this dissertation addresses these gaps in knowledge. To address ancestral tribal use of sea otters and cetaceans I researched previously excavated faunal assemblages. The Par-Tee (35CLT20) and Palmrose (35CLT47) sites located in Seaside, on the northern Oregon coast, were home to the Clatsop and Tillamook at contact. Par-Tee and Palmrose were occupied at different times in the Late Holocene (~1850-1150 cal BP and ~2750-1500 cal BP, respectively). The two sites were excavated in the 1960s-1970s and contained an enormous quantity of well-preserved faunal remains. The Tahkenitch Landing (35DO130) site is located on the central Oregon coast, north of Reedsport, and was home to the Lower Umpqua Indians at contact. Tahkenitch Landing was occupied from the early to mid-Holocene (approximately 5000- v 3000 BP) and contained a large quantity of whale bones which were previously analyzed, but not identified to species level. I conducted zooarchaeological analysis of the sea otters from Par-Tee and Palmrose (NISP=2992) and cetaceans from Palmrose (N=1174) and Tahkenitch Landing (N=33). With my co-authors, I analyzed ancient DNA from 20 Seaside sea otter specimens and performed Zooarchaeology by Mass Spectrometry (ZooMS) and ancient DNA identifications of 158 cetacean specimens. These analyses provided new insight regarding precontact ancestral tribal use of sea otters and cetaceans and the historical ecologies of the animals. This dissertation provides a socio-ecological dataset with implications for potential reintroductions of sea otters and the conservation of cetaceans in Oregon today. This dissertation includes previously published and unpublished co-authored material. vi CURRICULUM VITAE NAME OF AUTHOR: Hannah P.

Madonna has held me to high standards, generously shared her knowledge, and helped me to navigate academia as a feminist and woman. She gave me complete independence but was always quick to help, and I am so appreciative of the opportunities for academic and personal growth she has afforded me. Dr. Stephen Dueppen has similarly generously given his time, knowledge, and puns. Before the pandemic, Stephen’s physical door was always open to talk through problems and I am grateful for, and miss, these chats. I thank Dr. Nelson Ting and Dr. Kirstin Sterner for welcoming me into their lab groups and encouraging my interests in ancient DNA and outreach, and Dr. Ryan Jones for bringing his Pacific environmental history perspective to my committee. I am deeply grateful to Dr. Courtney Hofman at the University of Oklahoma for giving me the opportunity, funding, and training to advance my sea otter research with ancient DNA. Courtney, her students, and colleagues welcomed me with warmth and generosity; the time I spent in Norman was among the most memorable of graduate school. I am lucky to count Courtney as a friend and colleague, and I am also grateful to Nihan Dağtaş, Dr. Tanvi Honap, Dr. Rita Austin, Dr. Krithi Sankaranarayanan, and Dr. Cara Monroe. Many thanks to Dr. Jon Erlandson, Dr. Pamela Endzweig, and Elizabeth Kallenbach at the Museum of Natural and Cultural History (MNCH) at UO for their support of this project and access to the Palmrose collection. At the National Museum of Natural History (NMNH) Torben Rick, Dave Rosenthal, Esther Rimer, and Amanda Lawrence (Department of Anthropology), and John Ossosky and Suzy Peurach (Division of Mammals) facilitated access to archaeological and comparative collections. Paul Collins at the Santa Barbara Museum of Natural History provided access to California sea otter teeth for aDNA analysis. This dissertation would not have been ix possible without the stewardship of these institutions and the dedicated employees who care for these collections. Dr. Rick Minor suggested the Tahkenitch Landing site as a source of archaeological whales, and Kevin Bruce and Molly Kirkpatrick at the Siuslaw National Forest facilitated the Tahkenitch loan and generously provided funds for AMS dates. Dr. Briece Edwards, Confederated Tribes of the Grand Ronde, suggested ethnographic sources. Dr. Robert Losey and Hope Loiselle shared their thoughts on the Seaside sites. Dr. Katherine Ralls provided feedback on Chapter III. The undergraduate students of Dr. Moss’s 2015, 2017, and 2019 zooarchaeology classes helped me via their class projects or volunteering their time to gain lab experience. Drs. Torben Rick and Melinda Zeder fostered my interest in zooarchaeology and encouraged me to pursue a Ph.D. Torrey served as my NMNH fellowship advisor and continues to mentor and guide me; I am eternally grateful for his support. Many years ago, Dr. Reuven Yeshurun shared his microscope with me and patiently trained me to identify cutmarks. Dr. Catherine West brought me to the field and has always been only a text away. I would like to thank my family and friends for their unwavering support, in whatever form it came. I do not have the space or words to properly express all the thanks I owe to you, but I love you and am so thankful to have you in my life. In short: “preesh.” Finally, I would like to thank Dave Hatch, whom I never met but was nonetheless an enormous source of inspiration for this project. Dave was a member of the Confederated Tribes of Siletz Indians and driving force behind the founding of the Elakha Alliance. His goal to bring sea otters home to Oregon inspired me to pursue the applied zooarchaeology of sea otters. This dissertation was financially supported by the Robert Hevey and Constance M. Filling Graduate Student Fellowship Award (NMNH), the University of Oklahoma, the Edna English Trust (MNCH), the UO Graduate School “Special Opps” grants, the UO Department of Anthropology Cheryl L. Harper Fellowship and Travel Funds, and the Siuslaw National Forest. x To my friends and family, especially my grandmother, Alice N. Wellman, the original family archaeologist, and in honor of Dave Hatch and the Oregon Elakha. xi TABLE OF CONTENTS Chapter Page I.

contact were skilled fisher-hunter-gatherers and savvy traders residing in a rich environment. The Oregon coast ecotone is home to diverse marine mammals – sea otters, seals, sea lions, porpoises, and whales – as well as other marine and terrestrial resources. Over time, Euro- Americans over-exploited these marine mammals and drove some species close to extinction, while inflicting disease, violence, and displacement upon Indigenous communities. Some marine mammal populations rebounded under state and federal laws, while others, such as the locally extinct Oregon sea otter, never recovered. Threats from Euro-American industrial-scale hunting in the U.S. are now over, but marine mammals living along the Northwest Coast today face new challenges, such as climate change, pollution, resource conflicts, and human-mediated disruptions, such as ship strikes. Sea otters and cetaceans are the foci of conservation efforts and concerns, and are also popular and charismatic fauna. While these taxa enjoy both general and academic interest in the present, little systematic study of these taxa and their use by, and relationship with, precontact peoples in Oregon has occurred. Tribal ancestors living on the Oregon coast prior to contact hunted or otherwise acquired sea otters and cetaceans and deposited the remains of these animals into middens and other archaeological features, but these remains are often overlooked and much remains to be analyzed. The first two objectives of this dissertation are to fully characterize how Oregon Coast Native Americans used sea otters and cetaceans prior to Euro-American contact, addressing longstanding assumptions regarding use of these species. Addressing ancestral tribal use of these species requires understanding the biological and ecological traits of the animals themselves, which comprises the third objective: to form a historical ecological dataset on the sea otter and cetacean species which can be applied to present- day conservation concerns. 2 1.2 Dissertation Outline This dissertation uses faunal remains from archaeological sites in Oregon to address how tribal ancestors used marine mammals (specifically cetaceans and the now- extirpated Oregon sea otter) prior to European contact, and gain insight on species’ historical ecologies prior to Euro-American depletion and extirpation. Chapter II of this dissertation addresses whether tribal ancestors were skinning sea otters to remove their pelts, to remove meat for dietary consumption, or both. Researchers have assumed that tribal ancestors skinned sea otters to obtain pelts based on the importance of the fur trade at contact, but other uses have not been critically evaluated. This chapter explores other purposes for which tribal ancestors might have used sea otters and describes possible dimensions to the human-animal relationship that may have been maintained between tribal ancestors and sea otters in their shared coastal environment. Precontact ancestral tribal use of, and socio-ecological relationships with, sea otters, have implications for potential future sea otter reintroductions which are currently undergoing a feasibility study led by the Elakha Alliance (a group pursuing the reintroduction of sea otters to Oregon). Chapter III addresses the Oregon sea otter’s historical ecology through an ancient DNA analysis of extirpated Oregon sea otters and their relatedness to other groups of extant sea otters elsewhere in the north Pacific. The results of Chapter III have implications for reintroduction efforts, particularly with regards to the source stock for possible relocations of sea otters to Oregon, and these results have already been disseminated to the Elakha Alliance. Chapter III includes previously published co- authored material with Rita M. Austin, Nihan D. Dağtaş, Madonna L. Moss, Torben C. Rick, and Courtney A. Hofman. Chapter IV shifts from sea otters to a much larger class of marine mammal: cetaceans (dolphins, porpoises, and whales). Indigenous groups south of the Makah tribe (in Washington state) on the Northwest Coast are typically categorized as non-whaling groups by anthropologists and historians, despite the presence of whale remains in archaeological sites in Oregon and California. As a result, ancestral tribal use of cetaceans has generally received more attention north of Oregon at archaeological sites 3 like Ozette (a Makah site) and ancestral Nuu-chah-nulth sites in British Columbia. Researchers have investigated whether tribal ancestors in northern Oregon were hunting or scavenging whales (Losey and Yang 2007; Sanchez 2014; Wellman et al. 2017), but discussion of cetacean use has been limited to mention of oil extraction for trade and consumption (Wellman et al. 2017:272) and other uses have not been systematically evaluated. This chapter moves beyond the focus on how Indigenous peoples living on the Oregon coast acquired whales, and instead seeks to fully characterize how residents of three different archaeological sites used cetaceans, as well as explore possible dimensions to precontact human-whale relationships. Chapter IV also provides a new, expanded dataset on the presence of cetacean species on the central and northern Oregon coasts during the Middle and Late Holocene, which may interest wildlife biologists working on cetacean conservation on the Northwest Coast. Chapter IV includes unpublished material with co-author Camilla Speller. 1.3 Research Programs: Human-Animal Studies and Historical Ecology In order to address the topics and questions described above, I draw from the research programs of human-animal studies and historical ecology. Human-animal studies seek to understand how humans and animals have interacted and related across temporal, social, cultural, and ecological contexts (Hill 2013; Mullin 2002). Human- animal studies draw from a wide variety of research methods and approaches, and in the case of archaeological applications, often rely heavily upon Traditional Ecological Knowledge or ethnographic analogy. Historical ecology seeks to describe the relationships between humans and their environments across temporal and spatial contexts (Balée 2006:75). Historical ecology is a descriptive approach that is necessary to create datasets from which to infer the human- animal relationships. In zooarchaeology, historical ecology is also sometimes used to refer to the ecological history of a specific species or family in the past, particularly when the species or community/population of interest is extinct or locally extirpated. Zooarchaeologists have emphasized the relevance of using zooarchaeological analyses to provide baseline biological and ecological data on such species, which can then be applied to modern conservation efforts (Lyman 2006). 4 Both of these approaches are readily applied in archaeological thought and analyses. Together they form an appropriate research program and framework with which to address: 1) questions of ancestral tribal use of marine mammals prior to Euro- American contact, and 2) the implications the resulting data may have for the animals themselves in terms of conservation and changes in their ecology and/or biology as a result of near-extirpation by Euro-American colonizers. 1.4 Archaeological Sites and Materials 1.4.1. Par-Tee and Palmrose (the “Seaside sites”) The majority of sea otters and cetaceans analyzed in this dissertation come from the “Seaside Collection,” comprised of materials from three coastal shell midden sites excavated between 1967 and 1977 at Seaside, Oregon (Phebus and Drucker 1979): Par- Tee (35CLT20), Palmrose (35CLT47), and Avenue Q (35CLT46). Par-Tee and Palmrose are the focus of this dissertation project, and are located in northern Oregon, roughly 15 miles south of the mouth of the Columbia River (Figure 1.1). What is now the town of Seaside formerly contained an ancient bay or estuary, which later filled to form the landscape present today (Connolly 1992, 1995; Phebus and Drucker 1979). Par-Tee is located closest to the shoreline and has undergone additional AMS dating which has refined the site occupation to 1850-1150 cal BP (or cal AD ~100-800; Sanchez et al. 2018). Palmrose is located slightly inland, closer to the proposed ancient quiet-water environment (Connolly 1995) and was occupied primarily 2750-1500 cal BP (Connolly 1992), although an early date of 4000 cal BP associated with whale bone may suggest early “intermittent and opportunistic” use of the Palmrose site (Connolly 1992:39). 5 Figure 1.1. Map showing location of the Seaside sites (Palmrose and Par-Tee) on the northern coast (black inset) and the Tahkenitch Landing site on the central coast (red inset). Made in ArcMap 10.0/Adobe Illustrator; data from Natural Earth, U.S. Census Bureau, Esri, DeLorme, HERE, and MapmyIndia. The sites were excavated by Robert Drucker and George Phebus and their volunteers in 5 × 5 foot (~1.5 × 1.5 m) units in arbitrary one-foot (~30 cm) levels. All sediments were screened over 1/4-inch mesh (Phebus and Drucker 1979). Unit depths varied, reaching up to six feet (1.8 m) in some places. Phebus and Drucker sampled approximately 550 m2 at Par-Tee, making it one of the largest excavations on the Northwest Coast south of Ozette (Losey and Yang 2007:662), including the extensive excavations at Čḯxwicən (Butler et al. 2019). Faunal and structural remains suggested possible part-time habitation at Par-Tee (Phebus and Drucker 1979), while seasonality of faunal remains and the discovery of the remains of a large, rectangular semi-subterranean 6 plank house suggested possible year-round residence at Palmrose (Aikens et al. 2011:247; Connolly 1992:168; Greenspan and Crockford 1992). The close relationship between the Tillamook and Clatsop tribes in the area has led to some ambiguity regarding cultural affiliation of the Seaside sites (Aikens et al. 2011; Arbolino et al. 2005; Phebus and Drucker 1979). At Euro-American contact, the Seaside area was home to the Penutian-speaking Clatsops (Chinookan peoples; Deur 2016) and likely the Salish-speaking Nehalem Tillamook (Jacobs 2003:2; Ray 1938). The groups were interconnected through marriage, trade, and language (Deur 2016; Boas 1894; Jacobs 2003). Seaside was also a documented location of Clatsop/Tillamook persistence following contact (Deur 2016). Today, the descendants of these groups are represented by the Confederated Tribes of the Grande Ronde and Confederated Tribes of Siletz Indians, as well as the federally unrecognized Confederated Tribes of Clatsop- Nehalem and Chinook Nation (Deur 2016; Johnson 2013:5). A repatriation report compiled by the Smithsonian Institution National Museum of Natural History (NMNH) determined Par-Tee was culturally affiliated with Tillamook descendants (Arbolino et al. 2005:ii), and Palmrose with Tillamook and Clatsop descendants (Arbolino et al. 2005:iii). The Par-Tee site assemblage is curated at the NMNH in Washington, D.C. The Palmrose assemblage is split between the NMNH and the Museum of Natural and Cultural History (MNCH) at the University of Oregon (UO) in Eugene. Par-Tee and Palmrose both contain enormous quantities of well-preserved faunal remains, and while research on these assemblages has occurred during the last two decades (Colten 2002, 2015; Loiselle 2020; Losey and Power 2005; Losey and Yang 2007; Sanchez 2014; Sanchez et al. 2016, 2018, 2020; Wellman et al. 2016; Wellman 2018; Wellman et al. 2020) much remains to be analyzed. Publications to date include a brief excavation report (Phebus and Drucker 1979), analysis of a subsample of faunal remains (Colten 2002, 2015), analyses of shellfish and fish remains (Losey and Power 2005; Sanchez et al. 2020), and AMS dating analyses (Sanchez et al. 2016, 2018). Connolly et al. (1992) revisited the Palmrose site in 1988 for limited excavations and reported additional faunal remains, artifacts, and studied the ancient geomorphology. Additional site notes and records are available in the archives at NMNH and MNCH. 7 1.4.2 The Tahkenitch Landing Site In addition to cetaceans from the Par-Tee and Palmrose sites, I re-analyzed the cetacean remains from the Tahkenitch Landing (35DO130) site. Tahkenitch Landing is located north of Reedsport on the central Oregon coast, on the shores of modern Tahkenitch Lake (Figure 4.1). At European contact, Lower Umpqua Indians resided in the Tahkenitch Landing area, while the Siuslaw and Coos tribes lived north and south, respectively (Minor and Toepel 1986:4). Today, descendants from these groups are represented by the federally recognized Confederated Tribes of Coos, Lower Umpqua, and Siuslaw Indians. The site was excavated in 1984 and 1985 in 1 m x 1 m units and 10 cm levels. The site is divided into three chronological components (I-III): the beginning of the first component dates to ~8000 BP and the end of the third component dates to post-3000 BP (McDowell and Minor 1986:41). The excavation yielded a significant amount of faunal material, of which a subsample was analyzed (Greenspan 1986:57). Component II contained approximately 31 whale bone specimens, several of which were tentatively identified to Balaenopteridae or Physeteridae (sperm [Physeter macrocephalus] whale) families, but further research was recommended (Greenspan 1986:64). Component II at the Tahkenitch Landing site dates to 5200-3000 BP (McDowell and Minor 1986:41), preceding the primary occupation of the Palmrose and Par-Tee sites. Tahkenitch Landing provides a different geographic and chronological context in which cetacean remains were acquired and deposited on the Oregon coast, and serves as a comparison to the northern Oregon sites of Par-Tee and Palmrose. The collection is stored in the Siuslaw National Forest Supervisor’s office in Corvallis, Oregon. Prior to the current study, we are unaware of any analysis of the Tahkenitch Landing site assemblage beyond the official excavation report (Minor and Toepel 1986). 8 CHAPTER II FOOD OR FUR? ANCESTRAL TRIBAL USE OF SEA OTTERS ON THE OREGON COAST PRIOR TO EUROPEAN CONTACT AND EXTIRPATION 2.1 Introduction 2.1.1 Sea Otters in Oregon Sea otters were driven to near extinction on the Pacific Northwest Coast in the 19th century due to the maritime fur trade. While sea otters previously ranged along the Pacific Rim from Japan to northern Mexico, the species is now restricted to parts of Russia, Alaska, British Columbia, Washington, and California (Bodkin 2015). Despite successful conservation efforts elsewhere on the Northwest Coast, reintroductions to Oregon in 1970 and 1971 failed (Bodkin 2015). As a result, sea otters are still considered extirpated in Oregon and are listed as “threatened” under the Oregon Endangered Species Act (ORS 496.171-496.192). Sea otters are of interest to diverse stakeholders in Oregon today, and are considered an ecological priority due to their role as a keystone species within kelp forest ecosystems (Estes and Palmisano 1974). Restoring sea otters to the Oregon coast is the explicit goal for the recently reestablished Elakha Alliance, initially founded by Siletz tribal member Dave Hatch (Hall 2019). Reflecting these conservation priorities, several zooarchaeological studies of Oregon sea otters have provided historical ecological data to inform future reintroduction efforts (e.g. Lyman 1988; Valentine et al. 2008; Wellman 2018; Wellman et al. 2020 [Chapter III]). Sea otters are culturally significant to Native American, First Nations, and Alaska Native groups who reside along the Northwest Coast. Precontact sea otter hunting and use has been described in the archaeological and ethnographic record for some regions and communities, but detailed zooarchaeological data are lacking for the Oregon coast (Hall 2019:117). Hall found that sea otters “frequently rank along with Steller sea lion and harbor seal among the top three” (2019:122) marine mammals in coastal Oregon faunal assemblages. Hall’s findings clearly indicate that sea otters were an important species prior to contact and the historical fur trade. Oregon archaeologists and historians agree with Hall that sea otters were important, but few have reported on use patterns or explored the precontact relationships between humans and sea otters. In a literature 9 review of pinniped and sea otter use in northern Oregon and southern Washington, Moss and Losey (2011:186) recommended more thorough and detailed zooarchaeological analyses to gain an understanding of sea otter use, but little progress has occurred since the time of their writing. The precontact socio-cultural details of sea otters on the Oregon coast remain unaddressed: how, why, and when were tribal ancestors using sea otters, and what was the nature of the human-sea otter relationship in the coastal Oregon landscape? 2.1.2 Current Study This study characterizes how precontact inhabitants of the Oregon coast used sea otters. I present the analysis of cutmarked sea otter remains from two archaeological sites from the northern Oregon coast to determine whether sea otters were processed for pelt removal, dietary consumption, or both. This study was undertaken with the explicit goal of disseminating results to tribal stakeholders to be used as desired or needed, while also contributing more broadly to understanding relationships between humans and fur- bearing marine mammals in the archaeological record. A core premise of this study is that sea otters were (and still are) an important coastal resource for tribal groups throughout the Pacific Northwest Coast. The analysis presented here is one of multiple lines of evidence affirming the importance of sea otters. These results are not a new revelation; I build upon current Oregon tribal positions and knowledge to affirm tribal assertions that the reintroduction of sea otters to Oregon would be a rekindling of a long human-animal relationship disrupted by colonial incursion and ecological exploitation by Euro-Americans (Hall 2019). The results of this study indicate that the inhabitants of the Par-Tee and Palmrose sites were skinning sea otters for their pelts prior to European contact. Sea otter muscle also appears to have been removed from parts of the skeleton, but it is not clear if this was for dietary consumption by humans. Sea otters were clearly processed, sometimes intensively, prior to their deposition in the archaeological record, and were an important coastal resource for Oregon tribal groups prior to and at Euro-American contact. 10 2.2 Background 2.2.1 Archaeological Sites and Materials The sea otters analyzed in this chapter come from the Par-Tee (35CLT20) and Palmrose (35CLT47) sites, coastal shell mounds excavated between 1967 and 1977 at Seaside, Oregon (Phebus and Drucker 1979). Par-Tee and Palmrose are located south of the Columbia River mouth (Figure 2.1). Figure 2.1. Map showing location of the Seaside (Palmrose and Par-Tee) sites on the Oregon coast. Made in ArcMap 10.0/Adobe Illustrator; data from Natural Earth, U.S. Census Bureau, Esri, DeLorme, HERE, and MapmyIndia. The Par-Tee site collection is curated at the NMNH in Washington, D.C. The Palmrose assemblage is split between the NMNH and the Museum of Natural and Cultural History (MNCH) at the University of Oregon (UO) in Eugene. Par-Tee and Palmrose both contain enormous quantities of well-preserved faunal remains, providing an ideal sample size for faunal analyses, and much remains to be analyzed. While full 11 descriptions of the artifact assemblages have not been published, sea otter bacula tools have been identified at Par-Tee (Robert Losey, personal communication, 7/23/2019). 2.2.2 Ethnographic Background Ethnographic research on the Chinook and Tillamook peoples began with Lewis and Clark’s arrival at the mouth of the Columbia, and was followed by that conducted by anthropologists including Franz Boas (1894) and Melville and Elizabeth Jacobs (Jacobs 2003; Pearson 1990). These sources recorded how tribes on the Oregon Coast used sea otters. Lewis and Clark frequently wrote about sea otters and their pelts and are cited in various sources (Lewis and Clark 2005; Sauter and Johnson 1974; Ray 1938). Verne Ray (1938:114) noted “all of the early writers speak of sea otter robes in use by the Chinook but it is not certain whether they used the flesh for food or not.” The typical Chinookan method of making sea otter robes required two skins which were sewn together (Ray 1938:137). The Salmon River Tillamook used sea otters for clothing and bedding (Zobel 2002:309), and sea otter skins were highly valuable and coveted (Sauter and Johnson 1974:53). Tillamook shamans reportedly kept their powers in a bag made from sea otter skin (Sauter and Johnson 1974:120). Tillamook hunted “otters” for fur and a “valuable food source” (Sauter and Johnson 1974:5), but further discussion of otters related to subsistence is absent – it is possible Sauter and Johnson are referring to river otter (Lontra canadensis), since they do not specify “sea” otter. Clara Pearson, a Nehalem Tillamook informant interviewed in the early 1930s, did not discuss sea otters with regards to subsistence (Jacobs 2003:95) but recounted stories and myths including sea otters (Pearson 1990). For example, the story “The Invisible Husband” includes a specific reference to Seaside as the location where “all those men went sea-otter hunting” (Pearson 1990:20). “The Round Trip of Ice” describes a sea otter hunt with Ice and his men; they encounter a “[…] sea otter that was different looking. It was a sea otter all right but it had a white face” (Pearson 1990:3). The men cannot strike the sea otter and follow it back to the village where they find a young woman who looks just like the sea otter, along with the weapons they had fired at it (her). In “Moon’s Winter Dance,” all “types of people” attend, such as Dentalium, Bracelets, and “Those Tanned sea otter hides that only very wealthy people wear” 12 (Pearson 1990:150). In the “South West Wind Dance,” South Wind wears “quivers made from sea otter skins” while he creates the world (Sauter and Johnson 1974:125). These stories indicate that sea otters were important symbolically and economically, and were non-human persons/agents within the lower Columbia River landscape. 2.2.3 Previous Cutmark Studies 2.2.3.1 Alaska Tlingit Sea Otter/Seal Use and Experimental Skinning Study (Moss 2020). To determine if Tlingit ancestors were processing sea otters for dietary consumption, Madonna Moss (2020) compared cutmarked elements of seals (which were known to be processed for food) to cutmarked elements of sea otters from archaeological sites near Angoon, Southeast Alaska. Working with Sealaska Heritage Institute, she received permission to observe a Tlingit hunter, Kyle Barry, as he skinned a sea otter hunted under the Marine Mammal Protection Act (MMPA). Moss and colleagues obtained the resulting sea otter carcass, prepared the skeleton, and examined the bones to identify cutmarks left by the skinning. Moss concluded that cutmarks on the archaeological mandibles, tarsals, metatarsals, tibiae/fibulae, and ulnae/radii reflected skinning, while cutmarks on the femora/humerii were a result of pulling limbs away from the pelt during skinning. On the archaeological remains that she studied, Moss (2020:215) interpreted cutmarks on scapulae, vertebrae, innominates, and ribs as resulting from obtaining backstrap muscle for dietary consumption by dogs and possibly humans. One major methodological lesson from Moss’ analysis is that the “typical” patterns of cutmarks and their assigned functions (e.g., Binford 1981) were not necessarily applicable to sea otters, and that skinning resulted in cutmarks in unexpected areas following zooarchaeological conventions (Moss 2020:216). For example, the sea otter skinned by Mr. Barry was cutmarked on sternabra, a rib, radius/ulna, metacarpals, calcaneus, and metatarsals, all of which are consistent with skinning, and also on the innominate, femur, and fibula, which are not (Moss 2020:213). Moss (2020) worked with Tlingit individuals with expertise in sea otter hunting, skinning, and sewing. Today, Tlingit and other Alaska Natives use sea otters primarily as a source of material for sewing regalia, blankets, and handicrafts. To this end, Mr. Barry and others attempt to produce the largest skin possible, removing it from all around the 13 limbs. Mr. Barry produced a fully articulated sea otter carcass, so none of his cutmarks were made for disarticulation. Other people at different times and places could dismember a sea otter for the purpose of sharing small portions that could be used in a variety of ways, even as sources of smaller pieces of fur. 2.2.3.2 Small Carnivore Experimental Skinning Study (Implications for European Upper Palaeolithic) (Val and Mallye 2013). Val and Mallye (2013) conducted an experimental skinning study in which professional taxidermists skinned small carnivores found in Europe (Eurasian badges, stone and pine martens, a polecat) and Europe/North America (red foxes, a weasel). Val and Mallye (2013) recorded the resulting cutmark patterns and reported high frequencies of cutmarks on the cranium, lateral mandible, tarsals, metatarsals, phalanges, ulna/radius, tibia, and fibula (2013). Val and Mallye (2013:237) noted that forepaws and caudal vertebrae may remain in the fur upon removal from the skeleton, so an assemblage missing forepaws and caudal vertebrae may indicate that animals were skinned and the pelts containing the forepaws/caudal vertebrae were deposited elsewhere (2013:237). Conversely, an assemblage consisting solely of forepaws or caudal vertebrae (e.g., the stone marten remains at Çatal Hӧyük [Pawlowska and Marcizak et al. 2017]) may indicate pelts were deposited in the site. While Val and Mallye’s study was performed by modern taxidermists it is a useful comparison when considering cutmarks on fur-bearing mammals. 2.2.3.3 Umpqua-Eden and Seal Rock (Oregon) Archaeological Analysis (Lyman 1991). Lyman (1991) analyzed sea otter bones from two coastal Oregon sites: Umpqua-Eden (35DO83) and Seal Rock (35LNC14). Seal Rock yielded an NISP of 141 sea otter specimens, ~18% of which were cutmarked (Lyman 1991:227), and Umpqua-Eden yielded an NISP of 302, ~19% of which were cutmarked (1991:152). Lyman sketched each cutmark and categorized them by function (following Binford [1981], Howard [1973,1975], and Lyman [1987]). Using Binford’s (1981) three categories of cutmarks, Umpqua-Eden sea otter elements exhibited 31 dismemberment, 37 filleting, and 22 skinning marks (Lyman 1991:321-322), and Seal Rock elements exhibited 10 dismemberment, 12 filleting, and one skinning mark(s) (Lyman 1991:333-334). 14 Cutmarks classified by Lyman as dismemberment and filleting may not have been a result of dismemberment/filleting, but from different aspects of the skinning process, as recorded by Moss (2020) and Val and Mallye (2013). Only three innominates, three distal tibia, four calcaneii, four metatarsals, and five astragali were categorized as exhibiting skinning marks. At Umpqua-Eden, Lyman concluded that complete sea otter hindlimbs had been removed from carcasses because 62% of hip joint elements (% NISP) were cutmarked, followed by the shoulder joint (21%), elbow/ankle (both ~15%), and knee (~13%) (Lyman 1991:156). There were no cutmarks on the wrist joint. Lyman’s categorizations of “dismemberment” and “filleting” imply dietary consumption, but he did not explicitly discuss or draw specific conclusions regarding use. 2.3 Cutmark Methods 2.3.1 Cutmark Identification I examined the Par-Tee and Palmrose sea otter bones for cutmarks under 0.63x to 2x magnification. Cutmarks were described and those that were not too faint were photographed. Most cutmarks on longbones were sketched onto schematic drawings from Post (2006). I studied the muscular anatomy of the sea otter forelimb and hindlimb described by Howard (1973, 1975) as well as a dog anatomy textbook (Budras 2007) to identify possible fascia “targets” of the cutmarks to determine function. The placement of some cutmarks relative to muscle insertions or ligaments was extremely clear, while others were not. While determining cutmark “targets” provided an additional level of detail, it sometimes made function difficult to discern: most cutmark locations could reflect fascia cutmarks even when in locations considered standard for skinning, or vice versa (following Moss 2020). For example, cutmarks on the distal tibia have been cited as consistent with both disarticulation (Binford 1981:118) and skinning (Lyman 1991:322, 334; Val and Mallye 2013:234). 2.3.2 Tallying Cutmarks I calculated the percentage of each element that exhibited cutmarks (% NISP cutmarked, e.g., 69 of the total 116 femora specimens at Par-Tee are cutmarked, or 59%), as well as a count of cutmarks based on longbone location (e.g., 10 radii cutmarked 15 distally). While % NISP cutmarked does not account for fragmentation (Abe et al. 2002; Lyman 2008), longbone location counts do; it does not matter if the radius is fragmented, as long as it is clear which portion is cutmarked (Lyman 2008:285). Some authors have suggested that multiple cutmarks in one location on a single specimen reflect the effort of cutting or processing in that area (Milo 1998:106). Val and Mallye (2013:236) found that cutmark location remained consistent and cutmark frequency was a reflection of the processors’ skill. Consequently, the number of cutmarks in a given location may be less meaningful than cutmarks in the same location across multiple elements (as found by Val and Mallye 2003:237). In Moss’ experimental skinning study, Mr. Barry used a steel knife, but archaeological specimens would have been processed with stone or shell tools. The Par-Tee and Palmrose artifact assemblages contained chert scrapers and knives. Palmrose additionally contained a possible hafted shell blade (Museum of Natural and Cultural History, Eugene, Oregon [MNCH], North Coast Box 11 [NC 11], f. Field Notes [FN]). Sea otter pelts are thick with dense fur, and repeated cutmarks could be also due to the dulling of these blades rather than effort or the skill of the processor. 2.4 Results: Zooarchaeological Analysis 2.4.1 Par-Tee Sea Otter Remains 2.4.1.1 NISP and MNI. I analyzed the sea otter remains from 63 Par-Tee excavation units which yielded a sample size of 2024 NISP and 54 MNI (calculated using right femora: 30 adults and 24 juveniles). In terms of raw NISP, vertebrae, ribs, metatarsals, femora, phalanges, innominates, and humerii are the seven most abundant elements in the sample (Figure 2.2). These elements are representative of the axial skeleton (ribs and vertebrae), the hindlimb (femora, metatarsals, and phalanges), and the proximal forelimb (humerii). The next most abundant elements are innominates, ulnae, radii, and tibiae, which complete the emphasis on the hindlimb and forelimb. 16 Figure 2.2. NISP of sea otter elements in the Par-Tee sample. Vertebrae are represented primarily by the robust centra and are easily identified. Only 39 complete ribs were found in this analysis, but the majority of fragments included the diagnostic proximal end. The sample is not dominated by small rib fragments, possibly due to lack of recovery during excavation or difficulty identifying small, undiagnostic fragments. Regardless, fragmentation does not appear to be driving abundance of the vertebrae and ribs in the sample. Approximately 50% of metatarsals are complete, and the remainder are primarily undiagnostic distal ends. Pes phalanges are largely complete. Large proportions (~70%) of femora and humerii are complete, as are roughly 54% of tibiae, 40% of radii, and 20% of ulnae. Innominates are heavily fragmented, and a substantial number of unfused, partial juvenile innominates (NISP=34) are likely driving this abundance. Fibulae (which are long and extremely thin) are represented by the robust medial malleolus and varying intact diaphysis. Similarly, the scapulae are represented by the robust glenoid fossae. Crania fragments other than maxillae are not present. The maxillae are fragmented and underrepresented (N=38) relative to the comparatively robust mandibles (N=81), but 37 left upper P4s and 38 right lower P4s were reported in a previous analysis of all sea otter teeth in the assemblage (Wellman 2018:Table S1). The roughly equal representation of maxillary and mandibular teeth suggests that regardless of preservation, the cranium was processed and deposited. 0 100 200 300 400 500 NISP of Sea Otter Elements at Par-Tee 17 2.4.1.2 Element Representation. While axial and hindfoot elements exhibit high NISP counts, these elements are underrepresented if we consider the remains of 54 complete sea otter carcasses (assuming complete preservation). With 54 MNI, the sample should hypothetically contain 2700 vertebrae, 1512 ribs, 540 metatarsals, and 972 phalanges, but 16% (N=440), 24% (N=368), 33% (N=178), and 12% (N=114) of the expected totals are present, respectively (Figure 2.3). When vertebrae are reported by type, the sample contains 34% of the expected totals of lumbar, 24% of cervical, 14% of thoracic, and 7% of caudal vertebrae. Figure 2.3. Percent of sea otter elements expected in the Par-Tee sample, based on 54 MNI. Femora, innominates, and humerii are present in quantities over or close to expected totals (although due to fragmentation, especially of innominates, the actual percentage is likely below 100%; Figure 2.3). Ulnae, radii, and tibiae occur at 55%-60% of the expected frequencies; these percentages may also be lower due to fragmentation. Forefoot elements are extremely underrepresented in the Par-Tee sample: only 1% of expected metacarpal totals are present (Figure 2.3), and carpals/manus phalanges are absent. This may be due to the small size of these elements and archaeological recovery techniques, or the removal of the forepaws along with the pelt (Val and Mallye 2013:237). Alternatively, the lack of forefoot elements, combined with the substantial 0 20 40 60 80 100 120 Percent of Sea Otter Elements Expected in the Par-Tee Sample 18 underrepresentation of caudal vertebrae, may point to pelt removal and deposition outside of the excavated areas of the site. 2.4.1.3 Juveniles at Par-Tee. The Par-Tee sample contains a NISP of 240 juvenile specimens, and an MNI of 24 (calculated using right femora). Juvenile femora, humerii, innominates, ulnae, and mandibles are most abundant (Figure 2.4), likely because these elements have distinctive, diagnostic shapes and tend to be more robust even in a pup or juvenile sea otter. Fragile juvenile elements, such as ribs, are more likely to fragment and be unidentifiable. Figure 2.4. Adult and juvenile sea otter element abundance (NISP) in the Par-Tee sample. Determining ages of partial sea otter remains is difficult. I used the broad term “juvenile” to categorize elements missing one or both epiphyses, or in the case of the innominate, lacking fusion through the acetabulum. Using age criteria described in Nicholson et al. (2014), I determined age ranges for mandibles and maxillae: fourteen sea otters are aged ≤2 months old and eleven sea otters are aged ≤6.5 months old (Nicholson et al. 2014). Because the mandibles/ maxillae are fragmented and teeth are often missing, absolute ages could not be determined. These estimates are primarily limited to those based on the presence/absence of the lower deciduous premolars (pm3/pm4)/permanent molars (M1/M2) and upper 1st deciduous premolar (pm4)/permanent molar (M1). The 0 50 100 150 200 250 300 350 400 Adult and Juvenile NISP in the Par-Tee Sample ADULT JUVENILE 19 majority of sea otter elements in the Par-Tee sample are fused or show adult dentition (Nicholson et al. 2014). Sea otter pups can be born year round and juvenile remains are dispersed throughout levels at the site, making seasonality inferences difficult. It is interesting nonetheless to have so many juveniles in the sample and the age estimates (albeit approximate ranges) are informative. Sea otter pups are weaned on average at 6 months of age (Thometz et al. 2014), so the 2-6.5 month old pups in this sample would have been with or nearby their mothers and possibly hunted in association with the adult females. Distribution throughout the site lends additional evidence for co-capture: adults always co-occur in units containing juveniles and frequently within the same level. 2.4.1.4 Gnawing. The Par-Tee sample contains 28 specimens that exhibit carnivore tooth punctures and gnawing: one femur, two humerii, one innominate, nine metatarsals, one phalanx, one rib, one sternabra, five tibiae, four ulnae, and four vertebrae. This is likely an undercount, as other taphonomic signatures (wear/erosion/breakages) made toothmarks or gnawing difficult to identify. I noted several repeated irregular erosion patterns that, upon reflection, may have been gnawing. For example, I noted “divets” on the palmar and plantar surfaces of some distal metatarsals, as though they were ground between two canine teeth. A total of seven elements are both gnawed and cutmarked. Unfortunately, there is no clear spatial patterning at Par-Tee to differentiate between carnivore scavenging and domesticated dog gnawing, though the proximity of the gnawed elements both in and near the house feature at the Palmrose site may reflect domesticated dog activity. At contact dogs were reportedly human hunting partners, human companions, and possibly “sanitation workers,” eating trash and refuse (Mack 2015:65-66). 2.4.1.5 Pathology. The Par-Tee sample contained 33 specimens exhibiting pathologies: seventeen vertebrae exhibit signs of arthritis on the centrum, and five metatarsals, six phalanges, two sternabrae, four ribs, two tibiae, one radius, and one calcaneus show signs of active or healed infection. One radius is badly misshapen, but the cause is unclear. 20 2.4.1.6 Element Representation: Spatial Distribution. In order to identify any spatial patterning in skeletal element representation, I re-categorized elements based on their broader anatomical unit: cranium (teeth, mandibles, maxillae), the axial skeleton (vertebrae, sacra, ribs, sterna/sternabrae), hindlimb (innominates, femora, tibiae, fibulae), forelimb (scapulae, humerii, radii, ulnae), hindfoot (tarsals, metatarsals, pes phalanges) or forefoot (carpals, metacarpals, manus phalanges). I tallied the % NISP for each anatomical category within each excavation unit (Figures 2.5-2.8). Figure 2.5. Proportions of sea otter anatomical unit in the excavation units of the northeast quadrant of the Par-Tee site. Figure 2.6. Proportions of sea otter anatomical unit in the excavation units of the northwest quadrant of the Par-Tee site. 0 20 40 60 80 100 120 %hindlimb %axial %hindfoot %cranium %forelimb 0 20 40 60 80 100 120 NW19A NW20A NW21A %hindlimb %axial %hindfoot %cranium %forelimb 21 Figure 2.7. Proportions of sea otter anatomical unit in the excavation units of the southeast quadrant of the Par-Tee site. Figure 2.8. Proportions of sea otter anatomical unit in the excavation units of the southwest quadrant of the Par-Tee site. All units except for five (NE12H, NE12I, NE2B, NE7D, NW21A) contained elements from three or more of the anatomical categories. Yet because these five units produced very small samples (NISP≤10), this likely accounts for the lack of element diversity. 0 20 40 60 80 100 120 %hindlimb %axial %hindfoot %cranium %forelimb 0 20 40 60 80 100 120 %hindlimb %axial %hindfoot %cranium %forelimb 22 At Par-Tee, vertebrae and ribs are the two most abundant elements by NISP, and all units except one (SE6C, NISP=7) contain axial elements. Axial elements also make up a large portion of the unit NISP (almost half of units contain at least 50% or greater axial elements). Several units deviate from the majority axial component, although this is also attributable to small sample size (e.g., units NW20A, NW21A, NE2B). Unit NE2B (NISP=3), for example, contains two humerii (right and left) and a rib fragment, skewing the forelimb representation for the unit. Units NE12G and NE7B, however, do not appear to be skewed solely due to sample size. Unit NE12G contains six phalanges as well as left metatarsals I-V, and unit NE7B contains three phalanges and left metatarsals I-III and V. The excavation levels were imprecise (~1 ft), so it is difficult to ascertain whether deposition of groups of matching elements like left metatarsals accurately reflect processing activity/deposition of single sea otters within a specific area of the site, but it is possible. Overall, however, elements from a variety of anatomical units of the sea otter body appear to have been processed and deposited in units across the site without obvious patterning. 2.4.2 Palmrose Sea Otter Remains 2.4.2.1 NISP and MNI. I analyzed the sea otter remains from 34 excavation units from the Palmrose site, which yielded a 968 NISP and 22 MNI (calculated using right humerii [15 adults and 7 juveniles]). In terms of raw NISP, vertebrae, ribs, metatarsals, phalanges, and humerii are the most abundant elements (Figure 2.9). These elements are representative of the axial skeleton (ribs and vertebrae), the hindfoot (metatarsals and phalanges), and the proximal forelimb (humerii). The next most abundant elements are ulnae, femora, and mandibles, which complete the emphasis on the hindlimb and forelimb. 23 Figure 2.9. NISP of sea otter elements in the Palmrose sample. Vertebrae are represented primarily by the robust centra and are easily identified. Only nine complete ribs are found in this analysis, but the majority of fragments included the diagnostic proximal end. The sample is not dominated by small rib fragments, possibly due to lack of recovery during excavation or difficulty identifying small, undiagnostic fragments. Regardless, fragmentation does not appear to be driving abundance of the vertebrae and ribs in the sample. Approximately 42% of metatarsals are complete, and the remainder are primarily undiagnostic distal ends. Pes phalanges are largely complete. Large proportions of femora (~74%) and humerii (~65%) are complete, as are roughly ~50% of tibiae, ulnae, and radii. Innominates are heavily fragmented and are likely driving this abundance. Fibulae (which are long and extremely thin) are represented by the robust medial malleolus and varying intact diaphysis. Similarly, the scapulae are represented by the robust proximal articular ends. Crania fragments other than maxillae are not present. The maxillae are fragmented and underrepresented (N=14) compared to mandibles (N=29), but eight left upper M1s and 13 right lower M1s were reported in a previous analysis of all sea otter teeth in the assemblage (Wellman 2018: Table S1). The roughly equal representation of maxillary and mandibular teeth suggests that regardless of preservation, the cranium was processed and deposited. 0 50 100 150 200 250 300 NISP of Sea Otter Elements at Palmrose 24 2.4.2.2 Element Representation. While axial and hindfoot elements represent high NISP counts, these elements are underrepresented as at Par-Tee. With 22 MNI, the sample should hypothetically contain 1100 vertebrae, 616 ribs, 220 metatarsals, and 396 phalanges, but 24% (N=266), 20% (N=125), 55% (N=121), and 20% (N=80) of the expected frequencies are present, respectively (and these totals include fragmented/incomplete elements) (Figure 2.10). When vertebrae are reported by type the sample contains 38% of lumbar, 43% of cervical, 23% of thoracic, and 11% of caudal vertebrae expected totals. Humerii and ulnae are present in quantities over or close to expected totals (although due to fragmentation the actual percentages are likely lower; Figure 2.10). Femora, innominates, tibiae, and radii are represented by ~60%-75% of expected totals; these percentages may also be lower due to fragmentation. Forefoot elements are extremely underrepresented in the Palmrose sample as at Par-Tee; only 2% of expected metacarpal totals are present (Figure 2.10), and carpals/manus phalanges are absent. This may be due to the small size of these elements and archaeological recovery techniques, or the removal of the forepaws along with the pelt (Val and Mallye 2013:237). The lack of forefoot elements, combined with the substantial underrepresentation of caudal vertebrae, may point to pelt removal and deposition outside of the excavated areas of the site. Figure 2.10. Percent of sea otter elements expected in the Palmrose sample, based on 22 MNI. 0 20 40 60 80 100 120 Percent of Sea Otter Elements Expected in the Palmrose Sample 25 2.4.2.3 Juveniles at Palmrose. The Palmrose sample contains an NISP of 138 juveniles and an MNI of seven (calculated using right humerii). Vertebrae, humerii, femora, and mandibles are the most abundant juvenile remains (Figure 2.11). There are no juvenile maxillae fragments, but five sea otter mandibles are aged ≤2 months old and seven are aged ≤6.5 months old (Nicholson et al. 2014). As at Par-Tee, juveniles are distributed throughout the site and co-occur with adults, and the pups represented by mandibles are under or at weaning age (Thometz et al. 2014). Figure 2.11. Adult and juvenile sea otter element abundance (NISP) in the Palmrose sample. 2.4.2.4 Gnawing. The Palmrose sample contains 36 specimens exhibiting carnivore tooth punctures or gnawing: one astragalus, one baculum, three femora, five metatarsals, one phalanx, two radii, five ribs, one scapula, six tibiae, one ulna, and ten vertebrae. This is likely an undercount for the reasons described with regards to the Par-Tee assemblage. Gnawed elements are distributed throughout the site, including units within or in proximity to the house feature. A total of six elements are gnawed and cutmarked. While I cannot confirm that the gnawing was made by dogs, the proximity of the gnawed elements to and in the house feature may reflect domesticated dog activity. At contact dogs were reportedly human hunting partners (Jacobs 2003; Mack 2015; Ray 1938), human companions, and possibly “sanitation workers,” eating trash and refuse 0 50 100 150 200 Adult and Juvenile NISP in the Palmrose Sample ADULT JUVENILE 26 (Mack 2015:65-66). According to Ray (1938:117), Chinook dogs were allowed indoors, which might explain the presence of gnawed specimens within the house feature. 2.4.2.5 Pathology. The Palmrose sample contains 17 specimens exhibiting pathologies: ten elements exhibit signs of arthritis, while two metatarsals, two phalanges, one metacarpal, one rib, and one fibula appear to show signs of active or healed infection. 2.4.2.6 Element Representation: Spatial Distribution. As at Par-Tee, axial elements are present in the majority of units (except for SW8L and SW6D), and make up large proportions of the unit NISP (Figures 2.12-2.13). Figure 2.12. Proportions of sea otter anatomical unit in excavation units of the NE and NW quadrants at Palmrose. Figure 2.13. Proportions of sea otter anatomical unit in excavation units of the SE and SW quadrants at Palmrose. 0 20 40 60 80 100 120 %hindfoot %axial %cranium %hindlimb %forelimb 0 20 40 60 80 100 120 %hindfoot %axial %cranium %hindlimb %forelimb 27 SE8L (NISP=1) contains a radius and SW6D (NISP=12) contains forelimb and hindlimb/foot elements. Several units deviate from the majority axial representation, and these discrepancies may be due to small sample size combined with a lack of axial elements (e.g., units NE2M, NW6A, and SW1E, NISP≤9). While these units do sometimes contain interesting combinations of elements, the lack of stratigraphic resolution precludes clear conclusions regarding processing and deposition. For example, unit NE2M (NISP=7) contains two cervical and one thoracic vertebrae, an astragalus, and three right innominate bones across three levels, giving the impression that a large portion of the hindlimb was processed and deposited in this location. Unit NE1E contains teeth, mandibles, and an assortment of forelimb and hindlimb bones, and only two vertebrae and one sternum. Overall, it appears skeletal elements from all portions of the sea otter body were being processed and deposited in units across the site, with occasional exceptions. 2.5 Cutmark Results 2.5.1 Cutmarks at Par-Tee 2.5.1.1 Cutmark Sample. The Par-Tee sample contained 739 cutmarked specimens (37% of the overall NISP); 28% of juvenile specimens and 38% of adult specimens are cutmarked. Humerii and femora dominate % NISP cutmarked, followed by tarsals (driven by calcaneii/astragali), tibiae/fibulae (driven by tibiae), ulnae, and metatarsals (Figure 2.14). The only element that does not exhibit any cut marks is the axis vertebra (C2). Twenty different elements are cutmarked: bacula, maxillae fragments (included in Figure 2.14 as “crania”), patellae, phalanges, sterna/sternabrae, and sacrum fragments. There is an average of five cutmarks per specimen, and the highest average for a specific element is the average eight cutmarks per femur. 28 Figure 2.14. Abundance (% NISP) of cutmarked sea otter elements in the Par-Tee sample. The % NISP of cutmarked elements follows patterns described in Moss’ results. Sea otter humerii, ribs, metatarsals, radii/ulnae, and mandibles are cutmarked at both Par- Tee and the Angoon sites, but at higher proportions at Par-Tee (Moss 2020:211). Moss found sea otter femora and humerii (closely followed by vertebrae) had the highest % NISP cutmarked (2020:211). At Par-Tee, humerii and femora also represent the highest % NISP cutmarked, but are followed by tarsals, not vertebrae. At Par-Tee, 70% of humerii are cutmarked (versus Moss’ 10% and 20% for seals and sea otters, respectively) and 60% of femora are cutmarked (similar to the proportion of seal femora cutmarked in Moss’ analysis [~70%]) (2020:211). Cutmarked innominates at Par-Tee are intermediate (~35%) to the sea otter and seal innominates cutmarked in Moss (roughly 10% and 50%, respectively) (2020:211). At Par-Tee, tarsals, ulnae, radii, scapulae, vertebrae, ribs, and tibiae/fibulae are cutmarked at higher percentages than both sea otters and seals in Moss’s analysis (2020:211). Moss noted that eight different seal elements were cutmarked (no cutmarks on ribs, metatarsals, and mandibles) compared to 13 sea otter elements (2020:211). Lyman (1991) reported 12 elements cutmarked at Umpqua-Eden and eight at Seal Rock (1991:154, 228), while 20 different elements are cutmarked at Par-Tee. Moss suggested differences in anatomy affect how animals are processed, and the greater variety of sea otter elements exhibiting cutmarks may indicate a different approach or relative complexity when processing sea otters compared to seals (2020:210). 0 20 40 60 80 % NISP of Cutmarked Sea Otter Elements at Par-Tee 29 2.5.1.2 Cutmarks on the Axial Skeleton. Sterna and sternabrae at Par-Tee exhibit small nicks, which may be indicative of skinning and working the pelt away from the ribcage or vertebral column (Moss 2020:212; Val and Mallye 2013). At Par-Tee roughly half of ribs exhibit cutmarks on the shaft; the other half exhibit cutmarks on the head and/or neck. Cutmarks on the rib shaft may result from peeling the pelt away from the rib cage or stripping thoracic muscles. The rib head/neck cutmarks may reflect skinning or removing ribs from vertebrae. Vertebrae are cutmarked on processes or on the ventral centrum. Cutmarks to spinous processes may be the result of backstrap muscle removal (Figure 2.15), while ventral cutmarks may be from rib removal or gutting the animal (Moss 2020:215). The majority of vertebrae cutmarks at Par-Tee are located on the ventral centrum (Figure 2.16). Moss described a similar pattern in her data and suggested vertebrae cutmarks reflected butchering of the axial skeleton to obtain backstrap for either human or dog consumption (Moss 2020:215). Pulling the pelt from the vertebral column would not make cutmarks through the backstrap to the spinous process, nor would skinning explain the ventral vertebral cutmarks (Val and Mallye 2013:236). Figure 2.15. A thoracic vertebra cutmarked at the base of the spinous process, possibly indicative of backstrap removal (scale in cm; Palmrose unit SE4D-3). 30 Figure 2.16. A lumbar vertebra cutmarked on the ventral centrum (scale in cm; Palmrose unit SE3B-4). 2.5.1.3 Cutmarks on the Forelimb. Scapulae at Par-Tee are cutmarked on the ventral blade surface at the edges of the subscapular fossa (origin of the subscapularis muscle) (Figure 2.17). The cutmarks may have resulted from working under the scapula to separate it from the rib cage; cutmarks underneath the scapula are unlikely to result from skinning. Several humerii are cutmarked near the lesser tuberosity (insertion of the subscapularis). Taken together, these cutmarks may reflect efforts to sever the subscapularis and separate the humerus from the scapula. Humerii are cutmarked in various locations, particularly on or near the distal epiphyses. Multiple specimens are cutmarked above the anterior trochlea, as well as on/near the medial epicondylar ridge and foramen (Figure 2.18). These cutmarks may reflect disarticulation of, or difficulty skinning around, the elbow joint. Figure 2.17. A scapula cutmarked ventrally, on the edge of the subscapular fossa (scale in cm; Palmrose unit NE4C-3). 31 Figure 2.18. A distal humerus cutmarked on the medial epicondylar ridge (scale in cm; Palmrose unit SE3C-5). Radii and ulnae are also cutmarked in various locations, particularly on the proximal end. Radii are frequently cutmarked under the radial head and along the anterior/posterior diaphysis. Ulnae are frequently cutmarked on/near the olecranon process and on the medial fossa (insertion for multiple brachialis muscles). Some ulnae specimens are cutmarked on the posterior and medial diaphyses where Howard (1973) labeled muscles absent. Both elements exhibit infrequent distal cutmarks. The ulnae/radii cutmarks may reflect skinning, especially in places where fascia are not present (Val and Mallye 2013:236). The cutmark activity on the lower forelimb is surprising given the relatively small size of it’s muscles relative to the hindlimb. Perhaps these cutmarks do not reflect muscle removal but the separation of the radii and ulnae: these elements are robust and could be used for specialized tool manufacture (e.g. an ulna awl, bone point). The bones of the forepaws (manus phalanges, metacarpals, and carpals) are underrepresented at Par-Tee, but several metacarpals exhibit cutmarks on the palmar surface and likely reflect skinning. 2.5.1.4 Cutmarks on the Hindlimb. Innominates are cutmarked in various locations. Repeated locations included the iliofemoral ligament attachments and the gluteus medius, 32 obdurator externus, and pectineus muscle origins. These muscles and ligaments insert in the proximal femur. Approximately half of cutmarked innominates exhibit cutmarks on or near the acetabulum and may reflect leverage applied to the joint while skinning as described by Moss (2020:215). Muscle and ligament attachments around the acetabulum anchor the femoral head, so these cutmarks may also reflect disarticulation. Femora are cutmarked on the diaphyses and epiphyses. Cutmarks on the proximal end are at muscle insertions (e.g., the greater/lesser trochanter). Femoral necks (the location of the iliofemoral ligaments) are frequently cutmarked (Figure 2.19). Distal cutmarks are frequently superior to the lateral and medial condyles (on or near the gastrocnemius origin) (Figure 2.19). Three femora are cutmarked on a distal condyle, which may reflect a knife slip during disarticulation or working the pelt away from the knee joint. Tibiae are cutmarked at various locations, especially distally (Figure 2.20). Approximately half of cutmarked tibiae exhibit cutmarks on or immediately around the medial malleolus. Tendons and ligaments are present on the distal tibia underneath retinacula and may be severed for disarticulation or skinning (Val and Mallye 2013:236). Fibulae are primarily cutmarked on the lateral shaft; two are cutmarked on the lateral malleolus. Cutmarks to the fibulae may be due to skinning (Moss 2020:213; Val and Mallye 2013:236). Figure 2.19. A distal femur cutmarked on and around the medial gastrocnemius origin (L) and a proximal femur cutmarked on the femoral neck (R) (scales in cm; Palmrose units NE1J-3 and SE1M-3). 33 Figure 2.20. A tibia cutmarked on the medio-distal aspect (scale in cm; Palmrose unit SE1N-6). Cutmarks on the astragalus, calcaneus, and other tarsals likely reflect skinning (Val and Mallye 2013:230), but may also be due to disarticulation following Binford (1981). One Par-Tee calcaneus has over 15 cutmarks on the posterior surface (Figure 2.21), possibly reflecting efforts to sever the calcaneal tendon or difficulty working through the pelt at the ankle joint. Cutmarks on the phalanges and metatarsals likely reflect skinning (Val and Mallye 2013). Figure 2.21. Calcaneus exhibiting cutmarks on the posterior surface (scale in cm; Par- Tee unit NE8F-6). 34 2.5.1.5 Cutmarks on the Cranium. Par-Tee mandibles are frequently cutmarked on the lateral or inferior horizontal ramus which reflects skinning (Val and Mallye 2013). Several are cutmarked on the ascending ramus which may indicate removal of the mandible from the cranium (several muscles originate/insert at that location). Several maxilla fragments are cutmarked which likely reflect skinning. 2.5.1.6 Cutmark Patterns on Longbones. I categorized longbone cutmark locations for each specimen as follows: 1) on the diaphysis proper (“Diaph”) 2) on/near either the proximal or distal epiphysis (“Prox”/”Dist”) 3) on/near both the proximal and distal epiphyses (“P_D”) 4) on either the proximal or distal end and diaphysis (“P_Di”/“Di_D”) 5) on both the proximal and distal ends and diaphysis (“P_Di_D”) I tallied the number of cutmarked locations described above, the total diaphysis cutmarks (Total Diaph), and the total of specimens that were cutmarked in multiple locations (“Total Multi”) (Table 2.1). Because the specimens analyzed were not always complete, tallying the locations of cutmarks helps account for fragmentation by providing an overall characterization of longbone locations that exhibit cutmarks (Lyman 2008:285). Table 2.1. Cutmarks on Par-Tee forelimb and hindlimb longbones based on location. In the Par-Tee sample 29 femora, seven tibiae, four fibulae, 34 humerii, eight radii, and nine ulnae are cutmarked on the diaphysis. Following standard conventions (Binford 1981; Lyman 1991) these diaphysis cutmarks may reflect muscle removal from the element. Femora and humerii are most frequently cutmarked at the proximal and distal ends (or both). A combined 46 femora are cutmarked at the proximal end and 36 are 35 cutmarked distally. A total of 22 humerii are cutmarked at the proximal end and 53 are cutmarked distally. Tibiae are cutmarked proximally (N=7) and distally (N=25). Conversely, 12 radii are cutmarked proximally and three distally; 18 ulnae are cutmarked proximally and eight distally. I totaled these cutmark locations and labeled a template of sea otter skeleton with these frequencies (Figure 2.22). These groupings suggest that the hip, knee, elbow, and ankle joints were intensively processed relative to other joints. When the % NISP cutmarked is calculated by major joint, the hip (38%) and elbow (36%) joints actually rank below the ankle joint (42%) in overall processing (Figure 2.23). Figure 2.22. Sea otter skeleton with total longbone cutmarks from the Par-Tee sample tallied by location (Table 2.1). Circle size and color corresponds to number of cuts at location (proximal, distal, diaphysis). Illustration by Keeley Davies. 36 Figure 2.23. Percent NISP of sea otter elements cutmarked in the Par-Tee sample (calculated by joint). Some complete individual elements provide an additional impression of cutmark intensity. For example, 15 complete femora are cutmarked at both ends and eight are cutmarked at both ends and the diaphysis; 14 complete humerii are cutmarked at both ends and 4 are cutmarked at both ends and diaphysis. Tibiae, radii, and ulnae do not follow these patterns, instead exhibiting more cutmarks at the articular ends (either distal/proximal or both). 2.5.1.7 Par-Tee Cutmark Patterns. The Par-Tee sample yielded a notably high overall proportion of cutmarked specimens (37%), especially compared to the proportions found by Moss (13%; 2020:210) and Lyman (18% and 19%; 1991:151, 227). The humerii and femora are cutmarked in multiple regions and are overall more intensively cutmarked than the tibiae, ulnae, and radii (including when calculated by percentage [% multi, Table 2.1] to account for the higher NISP of femora and humerii). Femora and humerii specimens show relatively large numbers of cuts to the diaphysis (which may indicate muscle removal, interpreted as “filleting” by Lyman [1991]) but there are more cutmarks to the distal and/or proximal epiphyses at the hip, elbow, and ankle joints (Figure 2.22). The hip joint was also intensively processed at the Umpqua-Eden site (Lyman 1991:156) and in Moss’s analysis (2020:211). The processing on the hip and elbow joints could indicate dismemberment (Lyman 1991; Binford 1981) or skinning (Moss 2020; Val and Mallye 2013). The processing at the ankle joint could also reflect both, but the distal tibiae cutmarks correspond to the cutmark activity recorded in that location by 0 10 20 30 40 50 ankle hip elbow shoulder knee wrist % NISP cutmarked joints at Par-Tee 37 Val and Mallye (2013). A large proportion of tarsals at Par-Tee are cutmarked, corresponding with the distal tibiae cutmarks. The distal humerii and proximal radii/ulnae exhibit more cutmarks which could reflect dismemberment or skinning; Moss (2020:212) reported the forelimbs were pulled tightly into the body requiring extra leverage at the elbow joint during skinning. These cutmarks could also reflect efforts to remove the lower forelimb from the humerus. The axial skeleton is cutmarked, possibly indicating backstrap/thoracic muscle removal, and the mandibles are cutmarked primarily in locations associated with skinning. 2.5.2 Cutmarks at Palmrose 2.5.2.1 Cutmark Sample. The Palmrose sample contained 160 cutmarked specimens, or 17% of the overall NISP: 11% of juvenile elements and 18% of adult elements are cutmarked. Innominates dominate % NISP cutmarked (Figure 2.24), followed by tibiae/fibulae (driven by tibiae), humerii, femora, and tarsals (driven by calcaneii/astragali). There is an average of three cutmarks per specimen in the assemblage, (lower than at Par-Tee), and the highest average for a specific element is the average of five cutmarks per humerus, tibia, and ulna. Figure 2.24. Abundance (% NISP) of cutmarked sea otter elements in the Palmrose sample. The % NISP of cutmarked elements follows patterns described in Moss’ results. Sea otter innominates, tibiae, humerii, ulnae/radii, and mandibles are cutmarked at both Palmrose and the Angoon sites, but at higher proportions at Palmrose (Moss 2020:211). 0 10 20 30 40 50 % NISP of Cutmarked Sea Otter Elements at Palmrose 38 Moss found sea otter femora and humerii (closely followed by vertebrae) had the highest % NISP cutmarked (2020:211). At Palmrose, innominates and tibiae/fibulae represent the highest % NISP cutmarked, followed by humerii and femora. Moss recorded ~20% of vertebrae cutmarked, while at Palmrose only ~10% are cutmarked. At Palmrose ~27% of femora are cutmarked, as opposed to ~38% of sea otter and 70% of seal specimens from the Angoon sites. Cutmarked innominates at Palmrose are intermediate (~41%) to the cutmarked sea otter and seal innominates reported in Moss (roughly 10% and 50%, respectively). Fewer elements (N=14) are cutmarked at Palmrose (compared to 20 at Par-Tee) but this still represents a greater diversity of elements cutmarked compared to the 8 seal elements reported by Moss (2020) and is comparable to the 12 elements cutmarked at Seal Rock/Umpqua Eden (Lyman 1991;154, 228). It may indicate that sea otters were more intensively processed at Par-Tee than Palmrose, but the smaller sample size from Palmrose may also be driving this pattern (fewer bones identified means fewer opportunities to identify cutmarks). 2.5.2.2 Cutmarks on the Axial Skeleton. Sterna and sternabrae at Palmrose are not cutmarked. Roughly ~70% of ribs exhibit cutmarks on the shaft and ~30% exhibit cutmarks on the head and/or neck. Cutmarks on the rib shaft may result from peeling the pelt away from the rib cage or stripping thoracic muscles. The rib head/neck cutmarks may reflect skinning or removing ribs from vertebrae. Vertebrae are cutmarked on processes or on the ventral centrum. Cutmarks to spinous processes may be the result of backstrap muscle removal, while ventral cutmarks may be from rib removal or gutting the animal (Moss 2020:215). At Palmrose, processes and vertebral centra are cutmarked roughly equally. Following Moss, these cutmarks may indicate backstrap removal for either human or dog consumption (2020). 2.5.2.3 Cutmarks on the Forelimb. Scapulae at Palmrose (like Par-Tee) are cutmarked on the ventral blade surface, often on the edges of the subscapular fossa. The cutmarks may have resulted from separating the scapula from the rib cage. Humerii are cutmarked at various locations including inferior to the caput, on the lateral diaphysis, anterior 39 trochlea, and on/near the medial epicondylar ridge and foramen. Radii are cutmarked on the diaphyses but not on epiphyses. Ulnae are cutmarked proximally, distally, and on the diaphysis in roughly equal numbers. The ulnae/radii cutmarks at Palmrose do not exhibit clear patterning like at Par-Tee. Cutmarks to the radii may reflect skinning (following Val and Mallye 2013:236), while the ulnae cutmarks may reflect skinning, filleting, or disarticulation. The bones of the forepaws (manus phalanges, metacarpals, and carpals) are underrepresented at Palmrose, but several metacarpals exhibit cutmarks on the palmar surface and likely reflect skinning. 2.5.2.4 Cutmarks on the Hindlimb. Innominates are cutmarked in various locations. Repeated locations include those described at Par-Tee, such as the iliofemoral ligament attachments and the gluteus medius. These cutmarks could reflect leverage applied to the joint while skinning following Moss (2020), or disarticulation of the hindlimb at the hip joint. Femora are cutmarked on the diaphyses and epiphyses in roughly equal numbers. Cutmarks on the proximal end are at muscle insertions (e.g. the greater/lesser trochanter). Femoral necks (the location of the iliofemoral ligaments) are frequently cutmarked. Distal cutmarks are frequently superior to the lateral and medial condyles (on or near the gastrocnemius origin). Tibiae are cutmarked equally across diaphyses and epiphyses. One tibia is cutmarked repeatedly along the anterior crest which may reflect disarticulation or skinning following Val and Mallye (2013:234). Distal tibiae cutmarks are on/near the medial malleolus. One fibula is cutmarked proximally with small nicks, similar to Moss’ experimentally skinned sea otter (2020). Cutmarks on the astragalus, calcaneus, and other tarsals likely reflect skinning (Val and Mallye 2013), but may also be due to disarticulation (following Binford 1981). 2.5.2.5 Cutmarks on the Cranium. The cutmarked Palmrose mandibles exhibit cutmarks on the lateral horizontal ramus, reflecting skinning. Maxillae fragments at Palmrose are not cutmarked. 2.5.2.6 Cutmark Patterns on Longbones. I categorized longbone cutmark locations for each Palmrose specimen (Table 2.2). Unfortunately, the sample size of cutmarked 40 elements at Palmrose is smaller than at Par-Tee, so patterns evident in the Par-Tee sample are not as clear in the Palmrose sample. Table 2.2. Cutmarks on Palmrose forelimb and hindlimb longbones based on location. From Palmrose, four femora, eight humerii, four tibiae, one fibulae, four radii, and one ulnae are cutmarked on the diaphysis. Following standard conventions (Binford 1981; Lyman 1991) these diaphysis cutmarks may reflect muscle removal from the element. Distribution of cutmarks across Palmrose longbone locations is roughly equal when visualized across the skeleton (Figure 2.25), unlike the Par-Tee sample in which proximal femora and distal humerii were clearly intensively processed (Figure 2.22). Figure 2.25. Sea otter skeleton with total longbone cutmarks from the Palmrose sample tallied by location (Table 2.2). Circle size and color corresponds to number of cuts at location (proximal, distal, diaphysis). Illustration by Keeley Davies. 41 The humerii at Palmrose do exhibit slightly more diaphysis cutmarks, and tibiae exhibit slightly more distal cutmarks; both of these patterns are also present at Par-Tee. When the % NISP cutmarked is calculated by major joint, the hip (26%) and ankle (21%) appear to be slightly more intensively processed compared to the shoulder (12%), knee (9%), and elbow/wrist (7%) (Figure 2.26). Figure 2.26. Percent NISP of sea otter elements cutmarked
