Maybe ancient mammal bone

[CSimpson176]

In addition to the possible orthocone fossil I found in the same creek, I found this mammal bone. I live about ten miles as the crow flies from Big Bone Lick State Park in Kentucky. I live on a cattle farm (have had horses on the farm before as well spanning at least 50 years). This bone struck me as looking quite old due to the coloration and the slight erosion on it. With me living on a cattle farm, I’m leaning towards it being some sort of bovid bone, but want to know your all’s opinion. Thanks!

Try the burn test. Hold a match or lighter to the bone. If it burns and smells of burnt hair, it still has collagen, and so would be modern. 

If no burn or smell, then it is fossil.

 

Water/rivers/lakes can change bone color relatively quickly.

I'm going to guess cow tibia.

@Harry Pristis would probably actually know.

I would say more likely horse. The last photo I believe shows where the astragalus fits, which is angled like in the photo.

Equus tibia

Agreed.

Horse astragalus I have.
