TAS blog post on Gahagan biface shape and new preprint on SocArXiv

A blog post associated with a project that John E. Dockall and I have been working on was recently added to the Texas Archeological Society’s website, and can be viewed here.

Illustrations of Gahagan bifaces from the Gahagan Mound site in Northwest Louisiana. We are now looking at flake scar and beveling morphology associated with Gahagan biface retouch and refurbishment by Caddo knappers.Illustrations of Gahagan bifaces from the Gahagan Mound site in Northwest Louisiana. We are now looking at flake scar and beveling morphology associated with Gahagan biface retouch and refurbishment by Caddo knappers.

The post provides a preview of morphological similarities and differences associated with Gahagan bifaces found in Caddo burial contexts, which are currently thought to have been produced in central Texas. The preprint has been uploaded to SSRN and SocArXiv while the associated article is in review. Links to the SocArXiv preprint and other readings associated with this project are included below.

I am a research associate in the Center for Regional Heritage Research at Stephen F. Austin State University, where my work is focused at the confluence of archaeology, art, engineering, computer science, and the humanities. I am particularly interested in the application of 3D technologies to archaeological problems, geometric morphometrics, network analyses, archaeological theory, and archaeological science.
