Sherds from aboriginally-made ceramic vessels have been recovered on sites dating after ca. 2000 years B.P. in the Yegua Creek drainage of the Brazos River basin in the Post Oak Savannah of Burleson, Lee, and Washington counties in east central Texas (Figure 1). These sherds are from several different wares, including sandy paste Goose Creek Plain sherds made by Mossy Grove peoples, ancestral Caddo tempered and decorated wares made in East Texas, bone-tempered sandy paste wares that may be representative of a local ceramic tradition, and bone-tempered sherds from Leon Plain vessels made by Central Texas Toyah phase peoples. None of the ceramic sherd assemblages from the 18 sites discussed herein are substantial, ranging only from 1-72 sherds per site (with an average of only 13.3 sherds per site), indicating that the use (much less their manufacture) of ceramic vessels by Post Oak Savannah aboriginal peoples was not of much significance in their way of life, but may signify interaction, trade, and exchange between them and other cultures, such as the Caddo, inland and coastal Mossy Grove, and Toyah phase peoples that relied on ceramic vessel manufacture and use as key parts of their subsistence pursuits. It is likely that the benefits of trade (ceramics being just one of the items that was being traded) between these different peoples was to help establish cooperative alliances, and reduce competition and violence in the region, and such alliances were established and maintained by aboriginal peoples over a long period of time in the region.
