A Comparison of Gahagan Biface Morphology across Caddo Features at the Gahagan Mound, George C. Davis, and Mounds Plantation Sites
This investigation follows a recent morphological study of the three largest samples of Gahagan bifaces, and seeks to further characterize local morphological variation using 64 intact or reconstructed Gahagan bifaces from contexts where two or more specimens were recovered at the Gahagan Mound, George C. Davis, and Mounds Plantation sites. Gahagan bifaces are thought to have been imported from central Texas hunter-gatherers. Bifaces were scanned and analyzed using the tools of geometric morphometrics to identify whether Gahagan biface morphology difers between and among Caddo features. Results provide a preview of the dynamic morphological relationships associated with Gahagan bifaces recovered from Caddo archaeological features. A preliminary sequence of geographic shape change is postulated for Gahagan bifaces that potentially articulates with modifications made by Caddo knappers, and not those of the hunter-gatherer groups thought to have manufactured them.
