Calcaneus ID- Nebraska

[OssifiedConscript]

Hello all. First of many IDs I will be requesting of the fossils I have found in the Verdigris Creek of Northeastern Nebraska.

This creek runs through the Valentine Formation which is roughly dated to 15 million years old, but is also known to cut through Pleistocene exposures.

This bone I found has almost certainly been gnawed on- it matched up to the size of one of the larger stem hipparions found around here, but I am still unsure whether it could possibly be camelid or anything else.

Let me know your thoughts!! Thank you.

"Calcaneus" is usually used for the human homolog.  "Calcaneum" is usually used for the non-human tarsal.  For comparison:

I’ve added a few more photos that might help with an ID. Thanks! And my mistake, it is most certainly a calcaneum and not a calcaneus, lol.

It is certainly from an artiodactyl, but if it's Miocene in age, there are a double-handful of possibilities.  Your best bet is to find a museum collection for comparison to identified bones.
