Pinniped metatarsal?

[ynot]

Hey Y'all,

I was cleaning some matrix pieces and this was exposed.

I think it is an Allodesmus metatarsal but would like other (more informed) opinions on it.

 

 

Thanks Everyone.

@Boesse, @Harry Pristis

Any input on this piece?

Thanks.

It looks a lot like the seal material that I have found in North Carolina.

If pressed, I would guess sea turtle phalanx.

That looks like it is a good fit!

Thanks @Harry Pristis

This is a proximal manual phalanx of Allodesmus kernensis from digit 1 (thumb). Here's an image from the photographic plates published by Ed Mitchell (1966) of Allodesmus "kelloggi" (=kernensis)

Thanks Bobby.

That is an exact match for My piece.

I am happy that I was close to being correct on this one.

Hi Tony,

 

You should get yourself a copy of Mitchell (1966).  I happened to find a cheap copy very early in my collecting and it has helped a lot in seeing the difference between whale and pinniped bones in the STH bonebed.  Sea tuttle phalanges do not tend to have as well formed bone ends as mammal bones, looking more pitted as in Harry's last example.
