Circular shell rings along the South Atlantic Coast of North America are the remnants of some of the earliest villages that emerged during the Late Archaic (5000–3000 BP). Many of these villages, however, were abandoned during the Terminal Late Archaic (ca 3800–3000 BP). We combine Bayesian chronological modeling with mollusk shell geochemistry and oyster paleobiology to understand the nature and timing of environmental change associated with the emergence and abandonment of circular shell ring villages on Sapelo Island, Georgia. Our Bayesian models indicate that Native Americans occupied the three Sapelo shell rings at varying times with some generational overlap. By the end of the complex’s occupation, only Ring III was occupied before abandonment ca. 3845 BP. Ring III also consists of statistically smaller oysters harvested from less saline estuaries compared to earlier occupations. Integrating shell biochemical and paleobiological data with recent tree ring analyses shows a clear pattern of environmental fluctuations throughout the period in which the rings were occupied. We argue that as the environment became unstable around 4300 BP, aggregation at villages provided a way to effectively manage fisheries that are highly sensitive to environmental change. However, with the eventual collapse of oyster fisheries and subsequent rebound in environmental conditions ca. post-3800 BP, people dispersed from shell rings, and shifted to non-marine subsistence economies and other types of settlements. This study provides the most comprehensive evidence for correlations between large-scale environmental change and societal transformations on the Georgia coast during the Late Archaic period.

Toad bones, sometimes occurring in great numbers in pit features and other contexts in Native American village and mound sites in the Appalachian Summit, have been interpreted as evidence that toads were consumed, used for their purportedly hallucinogenic toad venom, placed as ritual deposits, or naturally entrapped/intrusive. A paucity or lack of bones of the head in some contexts is suggestive of decapitation and consumption of toads. Alternatively, bones of the head may be less preservable, recoverable, or identifiable. This study examines toad remains on Appalachian Summit late precontact and contact period sites, reviews previous experimentation, and presents a new experimental study undertaken to identify agencies of accumulation. We propose that toads were regularly consumed and possibly as part of ritualized events associated with village and mound construction. The temporal and geographic restriction of this practice to the Pisgah and Qualla phases of the Appalachian Summit suggests subsistence ethnicity as alluded to in historical accounts.
