Proximal tibia

I hope there’s enough of this piece to correctly identify. It looks like a proximal tibia of something large like bison, horse, camel or maybe tapir?  @Harry Pristis,

I think we can eliminate tibia.  Tibias typically have flat to dished-out articular surfaces.  My best guess (which in this case is tentative) is this is a proximal humerus from a carnivore.  You should get Hulbert to offer a guess.

Here are a couple more pictures. I did send these to Hulbert and he said it looks like a proximal tibia of an ungulate, like bison, camel ops or horse.
