ABSTRACT Folsom is an early Paleoindian archaeological tradition found in the North American West. Here we report new AMS radiocarbon dates for the Barger Gulch and Lindenmeier sites in Colorado along with unsuccessful dating attempts for Blackwater Draw, the Mitchell Locality, Shifting Sands, and Lipscomb on the Southern Plains. We applied Bayesian modeling using IntCal20 to our updated set of Folsom dates and estimate that the Folsom tradition lasted for a period spanning between 355–510 years at the 68 per cent credible interval or 325–650 years at the 95 per cent credible interval, starting sometime between 12,845–12,770 calendar years ago (cal yr BP) and ending sometime between 12,400–12,255 cal yr BP. Additionally, we model the spans of the start and end boundaries and find that both the adoption and abandonment of Folsom technology occurred over relatively short periods, less than 100 years and likely less than 50 years.

ABSTRACT By 16,000 calendar years ago, glacial melt waters from the ice masses in the basins which would hold lakes Erie, Huron, and Michigan had sculpted vast sandy plains with innumerable kettle lakes, gravel hills, and former channels. These provided a mosaic of marshes, open herbaceous vegetation, and patches of forest sustaining a diversity of herbivores. This rich ecosystem was the home of forager groups using different stone tool assemblages at different times. A small assemblage from the Belson site, made entirely on Attica chert from sources 235 km to the southwest, manifests characteristic Clovis techniques of biface reduction and basal preparation. At present it is the northwestern-most such occurrence in the Great Lakes region. If so, it should date about 13,000 calendar years ago. Further research will better characterize the tool industry and directly establish its age and ecological context.

ABSTRACT Experimental archaeology is a key component of research for reconstructing past human behaviors, and this approach has been a cornerstone for interpreting the earliest archaeological record in the Americas. In this paper, we survey the work of scholars who have used experimental archaeology to investigate the Paleoamerican stone tool record. We focus primarily on research published in the most recent decade. We organize our review according to four prevailing research themes: identifying objects intentionally made or modified by humans, measuring production efficiency, understanding projectile technologies, and reconstructing how tools were used. In each of these sections, we describe research questions and experimental designs and concisely summarize original investigators’ experimental results. Our hope is that this review will be a useful resource and inspire new experimental research.

ABSTRACT The recently reported discovery of cultural evidence at Chiquihuite Cave (Zacatecas, Mexico), produced by humans of at least 26,500 calendar years ago, is a major advance in research into early human occupations in the Americas. Thirteen of the 239 lithic artifacts recovered from the SC-C stratigraphic component, dated during and before the Last Glacial Maximum, are illustrated in Ardelean et al. (2020. “Evidence of Human Occupation in Mexico around the Last Glacial Maximum.” Nature 584: 87–92). Although waiting for more detailed technological studies, these types of artifacts have been reported in other sites, primarily in South America. The field evidence from sites predating the Last Glacial Maximum must now be included in all interpretations of the initial settlement of the Americas.

ABSTRACT Charred seeds, including those of goosefoot, amaranth, sedge, and possibly nightshade, were recovered from a Late Paleoindian context at the Bull Creek site in the Oklahoma panhandle. The use of these early successional plant resources at Bull Creek furthers our understanding of Paleoindian subsistence practices on the Plains, where preservation of plant remains is historically under-represented or under-reported. Bull Creek establishes an association between Paleoindians, broad-spectrum hunting, and wild-seed exploitation on the southern High Plains by 10,270 cal BP and documents an early phase of human/plant association in the mid latitudes of North America.
摘要：在俄克拉荷马州狭长地带的布尔溪遗址，从古印度晚期的环境中发现了烧焦的种子，包括鹅掌、苋、莎草，可能还有茄。Bull Creek这些早期演替植物资源的使用进一步加深了我们对平原上古印度生存实践的理解，在那里，植物遗骸的保护在历史上被低估或报道不足。Bull Creek通过10270 cal BP在南部高平原建立了古印第安人、广谱狩猎和野生种子开发之间的联系，并记录了北美洲中纬度地区人类/植物联系的早期阶段。

ABSTRACT This study reports the first results of geochemical sourcing of artifacts recovered from the 13,000-year-old occupation at Moose Creek in central Alaska, an assemblage assigned to the Nenana complex. During raw-material survey in the Nenana valley, we discovered a previously unrecognized source of dacite, and through portable X-ray fluorescence, here we present its geochemistry. Geochemical comparison of this source to artifacts in the Moose Creek assemblage indicates that the site’s Nenana-complex occupants used this raw material to produce both formal and informal tools, including a diagnostic triangular-shaped Chindadn point.

G., and L. Prates. 2018. “Clocking the Arrival of Homo sapiens in the Southern Cone of South America.” In New Perspectives on the Peopling of the Americas, edited by K. Harvati, G. Jäger, and H. Reyes Centeno, 79–106. Tübingen: Kerns Verlag]. They claimed that we purposefully ignored pertinent data to support our opinions, and that we made several mistakes when analyzing the evidence. In this article we demonstrate that we did not ignore any relevant data, and that the putative errors are in fact alternative interpretations based on the available data and recent studies about site formation processes.

ABSTRACT Recent analyses of lake sediments in Alaska have provided physical evidence supporting the genetically inferred Beringian Standstill Hypothesis and insight into the location of its occurrence. However, the biomarkers analyzed in these sediments are relatively novel paleoenvironmental proxies, so their reliability is understandably scrutinized. Further, the timing of human presence inferred from these sediments predates the oldest, unequivocal archaeological artifacts in Alaska. In this Perspective essay, I discuss the interpretation, limitations, and implications of the sedimentary analyses. Additionally, I explore the archaeological dilemma that they pose.
