Wildlife Spotting

This could go in the Identifying Animals Through Osteology mission at http://www.projectnoah.org/missions/8475425

After looking over the pictures, I'm withdrawing my original suggestion. It may be something like a horse or cow? What ever it was, it live a long life because the tops of the teeth are very worn.

Hi Billie, welcome to Project Noah. From the teeth shapes we can tell that this is a herbivore. To me, this looks very much like a whitetail deer (Odocoileus virginianus) jawbone fragment. A photo with the dirt washed off would make it more easy to identify.
