Calf Creek culture
Calf Creek Culture was a nomadic hunter-gatherer people who lived on the Great Plains of North America, especially in the area of what is today Oklahoma, artifacts having been found in such places as Beard's Bluff, Arkansas and Sand Springs, Oklahoma. The Calf Creek culture was active during the Archaic period in the Americas, approximately 5,000 years ago.
The Calf Creek people were noted for their use of large, heat-treated flint spearheads. In 2003, a 5,120±25-year-old bison skull was found on the banks of the Arkansas River by Kim Holt. The skull had a Calf Creek culture spearhead embedded just over the orbital of the right eye socket. The size of the spearhead, and the wound it inflicted further suggest that the Calf Creek also used atlatls.
