Summary

Starch grain analysis is a growing field in California archaeology, with the potential to significantly add to our understanding of prehistoric peoples. Using a non-destructive extraction method for field sampling bedrock mortars, I was able to extract microscopic plant residues from the mortar surface for analysis. The subsequent identifications were made using my ethnographically-informed comparative collection of modern native plants. The results of this research indicate that the function of bedrock mortars is significantly more varied than currently assumed, and that small seed processing played a much larger role in California subsistence than previously thought.
