What is this fossil? Mammoth? Mastodon? Other? Specimen 2

[Tom Carmichael]

This fossil came out of Florida. I'm assuming mastodon or mammoth. Foot Bone? Your thoughts? Appears to have some smooth, flat surfaces as shown in the second pic. Thank you.

Could it be cranial to have that opening like a foramen?  Maybe a skull or jaw fragment?

I think it is an ankle bone.. Metapodial,  Astragalus,   some thing like that... Mammoth/Mastodon size

Based on the two four flat articular surfaces I see in the second photo, this is definitely a mammoth/mastodon wrist/ankle bone.  The hole in the first picture is am erosional product, as is the rough surface that dominates  that same picture.

Looks like a magnum bone from a proboscidean to me.  I'll have to look more closely at my book at home to see if it's closer to Mammoth or mastodon, or you can try to look up examples and compare.

I have one quite similar that I’ve been calling a Proboscidean carpal

carpal is close.  The carpals are the small bones in the wrist.  tarsals are the small bones in the ankle.  And this is one of those.

I think I'm still in the magnum (carpal) camp.  Here are comparison photos from Olsen's Osteology for the Archeologist Number 3, mammoth magnum, pg. 28.  If you reverse the top left picture, it compares very well with the poster's second picture.
