A Morphometric Assessment of the Intended Function of Cached Clovis Points

A number of functions have been proposed for cached Clovis points. The least complicated hypothesis is that they were intended to arm hunting weapons. It has also been argued that they were produced for use in rituals or in connection with costly signaling displays. Lastly, it has been suggested that some cached Clovis points may have been used as saws. Here we report a study in which we morphometrically compared Clovis points from caches with Clovis points recovered from kill and camp sites to test two predictions of the hypothesis that cached Clovis points were intended to arm hunting weapons: 1) cached points should be the same shape as, but generally larger than, points from kill/camp sites, and 2) cached points and points from kill/camp sites should follow the same allometric trajectory. The results of the analyses are consistent with both predictions and therefore support the hypothesis. A follow-up review of the fit between the results of the analyses and the predictions of the other hypotheses indicates that the analyses support only the hunting equipment hypothesis. We conclude from this that cached Clovis points were likely produced with the intention of using them to arm hunting weapons

The Baller biface cache: A possible Clovis site in Hitchcock county, Nebraska

Twenty-six Clovis implement caches are known from western North America. In cases where time-sensitive artifacts (e.g., Clovis projectile points or mammoth ivory rods) or adequate information about their provenience and geological context are absent, assigning temporal and cultural affiliation has been challenging. Such is the case with a cache of eight large bifaces, four of which were donated by Albert E. Baller in the early 1900s to the University of Nebraska State Museum. The cache was discovered along with debitage within a small tributary of the Republican River in south-central Nebraska. The four donated Baller bifaces have been curated since the early 1900s. This study compared the physical properties, metrical attributes, and lithic reduction strategies exhibited by the bifaces with 119 similar large bifaces recovered from 10 Clovis caches. These comparisons suggest that the Baller bifaces may represent yet unreported Clovis cache from western North America
