This bison skull was found during an archaeological testing project of the Red Deer Creek Watershed in the eastern Texas panhandle in 1978. The skull, from the collection at Alibates Flint Quarries National Monument, is female. It is currently unknown if it dates to historic or prehistoric times. The hole in the skull is twelve centimeters in diameter and its purpose is also unknown. The official report for the project states: "the hole looks as if it might have been made with one of the heavy stone mauls that were popular with historic Plains Indians."
