On this episode we bring back Dr. Devin Pettigrew to discuss a paper that came out in 2021. The name of that paper is "On the efficacy of Clovis fluted points for hunting proboscideans" by Eren et. al. Dr. Pettigrew is an experimental archaeologist and together we discuss the pitfalls/successes of this study. We really dive deep into the article and the data they are using to summarize their argument. Dr. Pettigrew also gives us a background in the ballistics of atlatls as well as information around the use of ballistics gel/ceramics to interpret penetration effectiveness. Dr. Pettigrew then tell us about some of his current research and things he is studying.
