Projectile Point Size and Projectile Aerodynamics: An Exploratory Study

Abstract

Although often treated as complete cultural entities, projectile points are only the partial remnants of complex projectile delivery systems. The problem explored in this paper is the inferences that can be made about a prehistoric projectile from its one remaining part, the stone tip. A model is outlined to suggest how projectile point size, as measured by weight and neck width, may relate to the accuracy, flight stability, range, and killing power of the projectile. This model is used to suggest possible interpretations for size trends documented for a sample of bifaces from central Illinois. In conclusion, several avenues of research are suggested to help increase archaeologists’ ability to understand hafted bifaces and to explain changes in biface morphology.
