Abstract:
Levallois points are a prominent part of many Levantine Middle Paleolithic assemblages. They are either produced intentionally or incidentally by the Levallois core reduction technique and are of a generally similar shape, although the degree to which they were used as specialized tools has been questioned. Here, we examine Levallois points using geometric morphometric analyses to assess the range of shape variation in this artifact type. We then compare Levallois point shape variation and symmetry to a sample of Late Pleistocene-aged Folsom projectile points from North America. Folsom are highly standardized projectile points that current evidence suggests were primarily used for hunting ancient bison. Our results indicate that Levallois points are more variable and asymmetrical than Folsom and therefore more generalized than Folsom. Differences in manufacturing technique, hafting, and delivery system when used as weapons are posited as playing roles in the differences in shape and symmetry that we document.
