Hoax or History: A Bison Skull with Embedded Calf Creek Projectile Point

The discovery of a bison skull with protruding sections of a Calf Creek projectile point on a sand bar along the Arkansas River near Tulsa, Oklahoma, is investigated using the techniques of high-resolution X-ray computed tomography (CT), biometrics, and radiocarbon assay to determine its authenticity. This high-tech approach permits evaluation of the find without the extraction of the point. Converging lines of evidence suggest the association is authentic. This artifact contributes valuable knowledge to our understanding of middle Holocene hunters, including ispelling the idea that these objects were only employed as knives.
