An experimental model derived from ballistics tests has recently shown that the size of a flaked stone arrowhead significantly influences how well an arrow penetrates a target. Namely, the smaller the arrowhead, the deeper the penetration. However, large arrowheads have advantages too: they cause bigger wounds. I collected morphometric data from hundreds of arrowheads across Ohio to see whether they fall on the smaller, or larger, end of the experimental model to understand whether prehistoric hunters were more concerned with target penetration or wound size.
