Bison butchery at Cooper, a Folsom site on the Southern Plains

Cooper, a Folsom arroyo-trap bison kill site in northwest Oklahoma is composed of three large-scale kill episodes. The bison bones have been examined for butchering evidence and exploring the butchering pattern. Damage categories to cortical bone are indentation, cut mark, helical fracture, and impact blow. The 99 elements damaged are from 36 carcasses across all three kills, and damage morphology indicates both lithic and bone expediency tools were used in the butchering. Animals are being butchered in an upright position on their stomachs, with transverse and abdominal muscles the focal point. Experimental butchering of a bison replicates the reconstructed sequence and underscores a gourmet butchering style for the Cooper kills.
