Analysis of Lithic Material from Las Chachalacas

Summary

This is an abstract from the "SAA 2025: Individual Abstracts" session, at the 90th annual meeting of the Society for American Archaeology.

This poster presents the analysis of ground stone tools and chipped stone material from Las Chachalacas, Sonora, Mexico excavated in the winter of 2021 to 2022. Numerical dates suggest a periodic occupation from the Early Archaic period to the Early Agricultural period. The ground stone tool analysis focuses on the intensiveness of grain processing (wild or domesticates). This is facilitated by a measurement of the size and ground surface area of artifacts and depth of bottom stones (metates). The chipped stone artifacts, specifically the bifaces, permit an evaluation of the transition from a mobile hunter gatherer lifeway to a more sedentary lifeway. This was facilitated through an attribute analysis that included material type, stage of reduction, and dimensions of the chipped stone pieces. The use of bifaces as cores or tools was further evaluated through flake scar sizes and the presence of fine retouch.
