Identification of Horse Exploitation by Clovis Hunters Based on Protein Analysis

Positive results were obtained from protein residue analysis on three Clovis points from Wallys Beach, southwestern Alberta. Two tested positive for Equus, the third for a bovid, probably Bison or Bootherium. All genera are present in the site remains. This finding clearly demonstrates use of Equus by Clovis hunters. Four 14C dates indicate that the site was in use between 11,000 and 11,300 B.P.

Verifying the reliability of blood residue analysis on archaeological tools

Abstract An objective test of the validity of blood residue analysis as a technique for identifying archaeological tool use is presented. It is concluded that such residues do remain on tools for over 5600 years and that cross-over electrophoresis can accurately detect such residues. This technique provides an accurate means for identifying the animal species on which prehistoric tools were used. Routine museum curation procedures and normal soil processes do not necessarily destroy such residues. This test further supports the use of this technique for identification of unknown stains in forensic work.

Late Pleistocene horse and camel hunting at the southern margin of the ice-free corridor: Reassessing the age of Wally’s Beach, Canada

Significance Archaeological discoveries at Wally’s Beach, Canada, provide the only direct evidence of horse and camel hunting in the Americas at the end of the last Ice Age. Here, seven horses and one camel were attacked and butchered near a river crossing by prehistoric hunters. New radiocarbon dates revise the age of these kill and butchering localities to 13,300 y ago. Other North American kill and butchering sites show that prehistoric hunters preyed on 6 of the 36 genera of large mammals, called megafauna, for at least 2,000 y before these animals became extinct, around 12,700 y ago. Accurate dating is necessary to build meaningful chronologies for the Ice Age peopling of the Americas and to understand megafauna extinctions. The only certain evidence for prehistoric human hunting of horse and camel in North America occurs at the Wally’s Beach site, Canada. Here, the butchered remains of seven horses and one camel are associated with 29 nondiagnostic lithic artifacts. Twenty-seven new radiocarbon ages on the bones of these animals revise the age of these kill and butchering localities to 13,300 calibrated y B.P. The tight chronological clustering of the eight kill localities at Wally’s Beach indicates these animals were killed over a short period. Human hunting of horse and camel in Canada, coupled with mammoth, mastodon, sloth, and gomphothere hunting documented at other sites from 14,800–12,700 calibrated y B.P., show that 6 of the 36 genera of megafauna that went extinct by approximately 12,700 calibrated y B.P. were hunted by humans. This study shows the importance of accurate geochronology, without which significant discoveries will go unrecognized and the empirical data used to build models explaining the peopling of the Americas and Pleistocene extinctions will be in error.

Evidence for berry and maize processing on the canadian plains from starch grain analysis

The ethnographic and ethnohistoric records from the Northern and Canadian Plains indicate that a variety of plants were utilized by past peoples. These accounts provide two important insights into plant use in this region where very little archaeological evidence exists for plant utilization. First, plant processing tools are most likely to be unmodified lithic tools that may escape our recognition. Second, a variety of plants, which can be identified via starch grain analysis, were processed with these tools. This project analyzed the residues from two unmodified lithic grinding tools, identified as possible plant processing tools, for starch grains. Our results indicate that not only were a nuinber of wild plant species, such as choke cherry (Prunus virginiana), saskatoon berry (Amelanchier alnifolia) and likely prairie turnip (Psoralea esculenta), processed with these implements, but so too was maize (Zea mays). These results not only provide important insight with respect to identifying a tool class, plant use, and trade within our study area, but also provide an exceptional window into the use of wild plant species, an aspect of human history that is poorly understood in many regions of the world in addition to the Northern Plains.

Late pleistocene horse hunting at the Wally's Beach site (DhPg-8), Canada

Evidence from the Wallys Beach site in southwestern Alberta indicates Pleistocene horses were hunted by Clovis age peoples. A number of artifacts are associated with a horse skeleton, including a cut-marked hyoid indicative of butchering and a flake projecting below one of the vertebrae that establishes the archaeological material is not intrusive. A large unmodified cobble apparently was used to mark the kill or anchor the cache. Six other finds of horse remains also have associated lithic artifacts. Horse behavior is explored to speculate on hunting strategy. It is concluded that humans and climate change probably contributed to the late Pleistocene extinction of North American horses.

The use of immunological techniques in the analysis of archaeological materials — a response to Eisele; with report of studies at Head-Smashed-In Buffalo Jump

Eisele et al. in ANTIQUITY (1995) reported discouraging results from experiments to see if blood traces reliably survive on stone tools. Here, issue is taken with aspects of that study, and new research is reported from the celebrated buffalo-jump at Head-Smashed-In, southern Alberta. The great bone-bed there, consisting almost exclusively of bison bones, gives rare opportunity to study remains of a known single species under the genuine conditions of an archaeological site, rather than a supposing simulation.

Late Pleistocene Western Camel (Camelops Hesternus) Hunting in Southwestern Canada

Abstract Late Pleistocene large mammal extinctions in North America have been attributed to a number of factors or combination of factors, primarily climate change and human hunting, but the relative roles of these factors remain much debated. Clo-vis-period hunters exploited species such as mammoth, but many now extinct species such as camels were seemingly not hunted. Archaeological evidence from the Wally’s Beach site in southern Canada, including stone tools and butchered bone, provide the first evidence that Clovis people hunted North American camels. Archaeologists generally dismiss human hunting as a significant contributor to Pleistocene extinctions in North America, but Wally’s Beach demonstrates that human hunting was more inclusive than assumed and we must continue to consider hunting as a factor in Pleistocene extinctions.

Early Hunter-Gatherer Tool Use and Animal Exploitation: Protein and Microwear Evidence from the Central Savannah River Valley

Abstract Results of protein residue and lithic microwear analyses are reported for Paleoindian and Early Archaic stone tools from a Carolina bay sand rim on the Aiken Plateau of South Carolina, USA. Protein residue analysis is performed using crossover Immunoelectrophoresis (CIEP), and indicates positive results for Bovidae, Cervidae, Galliformes, and Meleagris gallopavo. These results are complemented by a larger immunological study of 135 diagnostic hafted bifaces from South Carolina and Georgia. Among other species identified, bovid residue was found on multiple Paleoindian hafted bifaces, an Early Archaic hafted biface, and a Middle Archaic hafted biface. Results suggest continuity of species selection and availability across the Pleistocene/Holocene boundary and provide no support for the exploitation of extinct fauna. The data do provide compelling evidence for a demographic shift and/or regional extirpation of Bovidae possibly as late as the early mid-Holocene in the Southeast. In addition, microwear analysis of artifacts from Flamingo Bay indicate intensive hide scraping, antler boring, bone graving/planing/pointing, wood whittling, and hafting traces. Microwear data suggest intentional snap-fracture or bipolarization of exhausted or broken Clovis points for reuse as hide scrapers, and use of large bifacial knives and unifacial scrapers in intensive defleshing activities consistent with large animal butchery.

The potential of citrate estimation in determining the sex of moa and kiwi

Abstract The citrate levels in lower limb bones from 12 moas and nine kiwis were estimated by Hess & Whites (1956) technique. As was found with human bone, the results reveal differing levels of citrate in male and female birds.

Implications of bone morphology for moa taxonomy and behavior

The limb bone skeleton of the moa, a family of extinct ratite birds endemic to New Zealand, is described with particular reference to the anatomical and functional significance of osteological landmark form variation. The results generally support the existing classification of moa. Four genera, Megalapteryx, Anomalopteryx, Dinornis, and Pachyornis, were found to be evolved within moa, with Emeus and Euryapteryx possibly being more primitive. Megalapteryx was found to be less mobile than other moa genera. The Dinornis species were found to be more cursorial and more mobile relative to other moa. They may also have had a different center of gravity. A marked development of the lower leg in Anomalopteryx suggested a digging habit associated with food procurement.
