Our next regular meeting will be Tuesday, October 15, 2019 at 7pm at Santa Rita Cantina's central location, 1206 W 38th St (26 Doors shopping center). Meetings are held on the third Tuesday of each month, except June and December. They are free and open to the public. For those who wish to come early, we gather around 5:45 PM for dinner, drinks, and fellowship. The short business meeting starts at 7:00 PM, followed by the guest speaker's presentation.

Details on the October program will be posted prior to the meeting. The September program featured Sergio Ayala, Project Archaeologist at the Gault School of Archaeological Research (GSAR), on

An Experimentally Supported Review of the Oldest Bifaces at the Gault site (41BL323), circa > 16,000 Years Ago cal BP

Abstract: Lithic analysis of the Gault Assemblage bifaces from the Area 15 and Area 12 excavations provided a working set of reference parameters to conduct experimental productions. This presentation outlines the strategies and tool-implement techniques embedded in the Gault Assemblage biface morphologies (technological behaviors) and flake scar signatures to discern both social group and individual level production behaviors on stone. The principles behind the Gault Assemblage bifacial tool manufacturing will be presented, highlighting the cultural elements/traits that differ from the younger Clovis production behaviors. The relationships between material procurement, tool production, and tool type and function will be discussed.

Sergio J Ayala, a native to South Central Texas, is a project archaeologist at the Gault School of Archaeological Research (GSAR), located at the Texas Archaeological Research Laboratory (TARL) at UT Austin. Sergio specializes in the use of experimental methods to support lithic analysis and behavioral studies. Sergio is also a technical illustrator. Some of Sergio's experimental stone tool replications are on display at the Meadows Center for Water and the Environment in San Marcos, Texas, and the Tales N Trails Museum in Nocona, Texas. Sergio is also currently completing his dissertation with the University of Exeter, UK, which focuses on a developed model of lithic analysis that other experimentalists can build upon.
