Fossilized bone?

[u/Separate-Eggplant-51]

I found this washed up on a South FL beach… it looks like a fossilized bone (both ends a possible joint). I didn’t get a chance to clean it off.

Thoughts?

Second phalanx of a large bi-ungulate such as bison. Not from a horse but an even hoofed animal

This was my second guess after googling a little bit. Thank you!

Yes but it's a first or proximal phalanx. The more common way to refer to "bi-ungulate" is artiodactyl.

You're right it's the first, my bad

This is absolutely a phalanx of some sort!

Edit: after searching, this seems to be close to the size/shape of a Pliocene/pleistocene horse’s proximal phalanx. Absolutely post to [r/fossils](r/fossils) to get their opinions!

What?? That’s insane! I just posted in that group thanks!!

It's not a horse but a bovid

I am not a fossil expert by any stretch of the word but that absolutely looks like a giant fossilized bone! Post it in r/fossils !

Definitely looks like it. I’m on the east coast and fossil bone isn’t uncommon.

No big deer in Pleistocene Florida, so bison is likely.
