“…Over the past decade, many archaeologists have become convinced that the Western Stemmed Tradition (WST) of the Intermountain West was coeval with, and probably even older than, the Clovis complex (e.g., Beck and Jones 2010;Davis et al 2012;Brown et al 2019;Rosencrance 2019;Smith et al 2019; but see Fiedel and Morrow 2012;Goebel and Keene 2014;Fiedel 2014;Fiedel et al 2021). This conviction is based primarily on evidence reported from two well-excavated and intensively 14 C-dated stratified sites: Paisley Caves in Oregon (Jenkins et al 2012(Jenkins et al , 2014(Jenkins et al , 2016) and Cooper's Ferry in Idaho (Davis and Schweger 2004;Davis et al 2014Davis et al , 2017Davis et al , 2019.…”

The study of the peopling of the Americas has been transformed in the past decade by astonishing progress in paleogenomic research. Ancient genomes now show that Native American ancestors were formed in Siberia or the Amur region by admixture of ca. 15–30% Ancient North Eurasian genes with those of East Asians. The Anzick infant, buried with Clovis bifaces at 12,900 cal BP, belonged to a group that was ancestral to later Native Central and South Americans. Fishtail points, derived from Clovis, mark the arrival and rapid expansion of Clovis-descended Paleoindians across South America, also evident in the sharp increase of radiocarbon dates, continent-wide, at 13,000–12,500 cal BP. In both North and South America, extinction of most genera of megafauna was virtually simultaneous with Paleoindian expansion. Human hunting must have been involved, perhaps in concert with other indirect impacts. Contrary to the alternative bolide impact theory, there is no evidence of a dramatic human population decline after 12,800 cal BP. Ancient genomes show that divergent lithic traditions after 13,000 cal BP need not be attributed to a separate Pacific Rim migration stream. Several recent finds raise the possibility that pre-Clovis people might have reached the Americas before 20,000 cal BP, but these precursors must have either failed to thrive, or were ultimately replaced by proto-Clovis or Clovis people. Consilient paleogenomic and archaeological data indicate that initial colonization by Paleoindian ancestors of living Native Americans occurred after 14,500 cal BP.

“…American archaeologists have indeed embraced new advances in Bayesian chronological modeling, establishing absolute chronologies for sites, regions, events, and trends independently of, or formally in conjunction with, materially established chronologies (e.g., Abel et al 2019; Brown et al 2019; Cobb et al 2015; Hart and Brumbach 2005; Krus and Cobb 2018; Lulewicz 2019a; Marquardt et al 2020; Miller 2018; Ritchison 2018; Thompson and Krus 2018; Thulman 2019). Such efforts, however, remain difficult for exploring European colonization.…”

Hernando de Soto's expedition through the southeastern United States between 1539 and 1543 is often regarded as a watershed moment for the collapse of Indigenous societies across the region. Historical narratives have proposed that extreme depopulation as a result of early contact destabilized Indigenous economies, politics, networks, and traditions. Although processes of depopulation and transformation were certainly set in motion by this and earlier colonial encounters, the timing, temporality, and heterogeneous rhythms of postcontact Indigenous histories remain unclear. Through the integration of radiocarbon and archaeological data from the Mississippian earthen platform mound at Dyar (9GE5) in central Georgia, we present a case of Indigenous endurance and resilience in the Oconee Valley that has long been obfuscated by materially based chronologies and typologies. Bayesian chronological modeling suggests that Indigenous Mississippian traditions persisted for up to 130 years beyond contact with European colonizers. We argue that advances in modeling radiocarbon dates, along with meaningful consultation/collaboration with descendant communities, can contribute to efforts that move us beyond a reliance on materially based chronologies that can distort and erase Indigenous histories.

“…Palabras clave: radiocarbon, modelado bayesiano, cronología, muestreo, simulación Large-scale radiocarbon dating programs at varying scales of analysis (e.g., from the single stratigraphic context to entire regions) have become a mainstay of archaeological research in North America, due in part to widespread advances in and adoption of Bayesian chronological modeling techniques (e.g., Abel et al 2019;Birch et al 2020;Brown et al 2019;Cobb et al 2015;Hamilton and Krus 2018;Holland-Lulewicz et al 2020;Kennett et al 2014;Krus and Cobb 2018;Krus et al 2015; Lulewicz 2018Lulewicz , 2019Manning et al 2018Ritchison 2018aRitchison , 2018bRitchison , 2020Thompson and Krus 2018;Thulman 2019). As evidenced by long histories of research in Europe, advances in both radiocarbon dating and Bayesian chronological modeling have greatly increased the analytical potential of both large and small radiocarbon datasets in ways that have allowed researchers to completely rethink approaches to archaeological practice and the narrative construction of the past (see Bayliss 2009; Bayliss and Bronk Bronk Ramsey 2009a;Buck 2004;Buck et al 1991Buck et al , 1996Hamilton and Krus 2018;Whittle et al 2011).…”

As the use of large-scale radiocarbon datasets becomes more common and applications of Bayesian chronological modeling become a standard aspect of archaeological practice, it is imperative that we grow a community of both effective users and consumers. Indeed, research proposals and publications now routinely employ Bayesian chronological modeling to estimate age ranges such as statistically informed starts, ends, and spans of archaeological phenomena. Although advances in interpretive techniques have been widely adopted, sampling strategies and determinations of appropriate sample sizes for radiocarbon data remain generally underdeveloped. As chronological models are only as robust as the information we feed into them, formal approaches to assessing the validity of model criteria and the appropriate number of radiocarbon dates deserve attention. In this article, through a series of commonly encountered scenarios, we present easy-to-follow instructions for running simulations that should be used to inform the design and construction of chronological models.
