Abstract
This article presents the specifics from the date combination process, and the subsequent production of summed probability distributions for radiocarbon (14C) assays from Caddo sites in East Texas. All 14C dates employed in this effort were collected from research and cultural resource management (CRM) reports and publications, were synthesized, and then recalibrated in version 4.2.2 of OxCal using IntCal09. These data are meant to augment those from previous analyses of radiocarbon samples from East Texas Caddo sites, assisting in refining these ideas further.
Highlights
The methods employed within this article were initially outlined within a temporal investigation of the Woodland period (Selden 2012), and have been used within a number of more recent publications aimed at delineating temporal trends within the Archaic (Selden 2013b) and Caddo periods (Selden and Perttula 2013a, 2013b), and are not discussed here
The 14C dates from the Hatchel site serve as an overview of the date combination process (Figure 1), after which all sites with nine or fewer dates are listed in chronological order (Figure 2a-e)
The application of some manner of chronometric hygiene is warranted, and while that will greatly diminish the number of 14C dates from the Caddo period, it should greatly increase the resolution of the current temporal model
