This X-ray shows something quite remarkable: a 13,800 year old mammoth rib with a man made projectile embedded in it. This makes it the oldest piece of hunting equipment found in North America by 800 years. It’s likely that this piece of bone became embedded in the mammoth’s rib as the projectile or spear was thrust into the animal’s torso in the attempt of getting a vital organ. Anthropologists have been able to conclude it’s age of 13,800 years after 4 decades since it’s discovery thanks to radiocarbon dating. The man made status of the point came from CT scans which revealed the razor sharp, worked edges along with a DNA analysis that revealed the bone came from a separate mastodon.
