The 12 Mile Creek site in western Kansas was the first site yielding a fluted projectile point to be excavated in North America by scientific personnel. The Bison from this kill site were used in forming the original concept of B. occidentalis . A new study of the site including radiocarbon dates and a pollen analysis suggests the kill took place in a pine parkland about 10,300 years ago. The artifact from this site reported by Williston seems to be a Clovis projectile point.
