Building experimental use-wear analogues for Clovis biface functions

This paper reports an experimental program designed to record microscopic use-wear traces obtained on replica Clovis points and bifaces used in impact, butchering, chopping, and scraping tasks. These experiments established the use-wear type, frequency, and distribution of use-wear traces acquired in bifacial tool tasks. Replica points and bifaces were photo-documented prior to use to monitor the use-wear accrued through multiple episodes and consider if a single tool used in multiple tasks could produce distinct wear patterns that were microscopically distinguishable. Ultimately, the experimental analogues served as the foundation to interpret use-wear traces detected on Clovis bifaces from the Gault site, Texas.
