An artifact constructed from a bison (Bison bison) hornsheath was recovered from the surface of a sandstone shelter also containing skeletal remains of bison and bighorn (Ovis Canadensis). Radiocarbon dating of bison, bighorn, and the artifact indicate that all co-occurred on the central Colorado Plateau, southeastern Utah, either between A. D. 1405 and A. D. 1420, or between A. D. 1535 and A. D. 1605. Skeletal remains of the bison imply that the animal was of the local faunal community during the transition between Protohistoric and Historic time.
