PROTEIN RESIDUE ANALYSIS OF ARTIFACTS FROM THE COOPER SITE AND THE JAKE BLUFF SITE, OKLAHOMA

Two Clovis projectile points from the Jake Bluff site (34HP60) and three Folsom projectile points from the Cooper site (34HP45) in northwest Oklahoma were analyzed for protein residues. Single soil samples from each of these sites also were tested. At the Jake Bluff site, the remains of 15 Bison antiquus were found associated with the two Clovis projectile points in the bottom of a short arroyo. A radiocarbon date of 10,750 BP suggests that this site post-dates mammoth extinction in the area and may represent a late-Clovis adaptation to bison hunting. The Cooper site represents a stratified Folsom bison kill site with three separate bone beds contained in alluvium in a small arroyo. One projectile point from each of the three bone beds and a single soil control from the middle kill were tested for protein residues.
