Recent excavations by the Ancient Southwest Texas Project of Texas State University sampled a previously undocumented Younger Dryas component from Eagle Cave in the Lower Pecos Canyonlands of Texas. This stratified assemblage consists of bison (Bison antiquus) bones in association with lithic artifacts and a hearth. Bayesian modeling yields an age of 12,660–12,480 cal BP, and analyses indicate behaviors associated with the processing of a juvenile bison and the manufacture and maintenance of lithic tools. This article presents spatial, faunal, macrobotanical, chronometric, geoarchaeological, and lithic analyses relating to the Younger Dryas component within Eagle Cave. The identification of the Younger Dryas occupation in Eagle Cave should encourage archaeologists to revisit previously excavated rockshelter sites in the Lower Pecos and beyond to evaluate deposits for unrecognized, older occupations.

The Tennessee Division of Archaeology documented an extensive Paleoindian lithic quarry and workshop at the Sinclair site in Tennessee in 2008. We present the first detailed description of the lithic assemblage here, which focuses on aspects of its prismatic blade technology. Quantitative and qualitative attributes of 117 blades are assessed to characterize the assemblage and investigate human behaviors related to its formation. We then compare the blades from Sinclair to other blade assemblages. Blades at Clovis workshop sites are large and generally unstandardized. Mobile Clovis bands selected long, highly standardized blades from workshop sites, cached them as resource insurance, and crafted and used them as tools at campsites. The prismatic blade assemblage at Sinclair and other sites throughout the Midsouth suggests that this region played an important role in the development of prismatic blade technology at the end of the Pleistocene.

In a recent issue of American Antiquity, two articles (Gill et al. 2021; Lyons et al. 2021) perpetuate the common misconception that dietary carbohydrates are an essential component of the human diet and that plants—the main source of dietary carbohydrates—must be consumed to promote health. In fact, carbohydrate is a nonessential macronutrient with adequate amounts of energy—the sole function of carbohydrates in the human diet—being produced via gluconeogenesis and ketogenesis in the absence of dietary carbohydrate. Additionally, both articles erroneously employ the term “dietary staple” in reference to geophyte consumption.

Architectural remains, especially domestic architecture, are essential for understanding the ways in which households organized themselves socially and economically in the past. Unfortunately, these remains are infrequently identified from Woodland period (1000 BC–AD 1000) archaeological sites along the Gulf Coast, an area home to well-known ceramic and mortuary traditions during this time. As a result, our knowledge of Woodland period households in the region is scant. In this article I present a newly discovered house from Letchworth (8JE337), a large Woodland period ceremonial center in northwest Florida, and compare it to the few published examples of houses from this region. I show that domestic architecture along the Gulf Coast during the Woodland period is diverse, suggesting differences in the organization of households and the historical development of ceremonial centers.

In a rejoinder to Gill et alia (2021), Martin (2022) accuses us of perpetuating misconceptions about human nutrition and erroneously describing geophytes as a dietary staple. We provide authoritative definitions for the terms “essential” and “dietary staple” to show that it is Martin who mischaracterizes and misunderstands the foundational role of geophytes and other plant foods to human diets and subsistence economies in Native North America outside of the Arctic. Recent data demonstrate that carbohydrate-rich geophytes were abundant, regularly utilized, and essential resources on the Northern Channel Islands, a dietary staple that was a rich source of calories and complemented the protein-rich shellfish and finfish that were also staple foods for the Island Chumash.

In response to Steve L. Martin's critique of our recent paper we provide further evidence in support of our central contention: that geophytes were a nutritionally important part of the precontact diet, and that they functioned as dietary, cultural, and economic staple foods for many peoples of the Pacific Northwest.

The Sheep Mountain juniper bark net, originally thought to be of Paleoindian age, was redated by Sundstrom and Walker (2021) to the Late Prehistoric period. Although the original investigators convincingly argued that the net was intended for use with mountain sheep or deer, Sundstrom and Walker suggest it was used to trap small game such as rabbits or sage grouse. Unfortunately, the authors ignore important information presented by the original investigators and misrepresent the archaeological record of the immediate area. The Sheep Mountain net is still best interpreted as designed for use to trap mountain sheep and deer.
