Large Joint Bone

[Shellseeker]

Found this one yesterday, hiding in 10 inches of gravel. My hunting partner suggested a mammoth knee pad or at least a bone connected with the knee joint.

The bone is 4x4.5x5 inches. Although banged-up it seems to be basically intact. All sugggestions appreciated.

I don't know what it is, but not mammoth knee-cap I think. I happened to have a woolly mammoth patella on hand and the sun hadn't quite gone down, so here's some pics for comparison:

I'm thinking elephant carpal or tarsal. Pretty far gone for much more detail.

Thanks for both responses -- I am moving from the knee to the ankle.. found this photo of a complete mastodon foot, http://fingerlakesfossilfarm.org/mammal_images/mastodon_foot_bone.jpg

Also I found what is likely a metapodial a couple of years back, which are the 4 just below the carpal/tarsal.

Curious that this link exists thru a Google but thru a TFF search.

I am pleased with your responses because I did not think there was enough detail to comment.
