Hyracodon?

[Peat Burns]

Hello TFF.

 

This was brought to me today with no location info.  It looks like Oligocene White River Group.  Person who brought it in said it was collected by his grandparents who took trips to S. Dakota, etc.  It is pretty "beat up".  My first thought was Hyracodon from the White River Group.  It's not Oreodont.  Teeth are heavily eroded.  The matrix is more reddish than anything I have collected in Nebraska, so maybe it's from S. Dakota?  Thoughts? @Nimravis, @jpc (darn blurry pics.  I even used a copy stand and timer...)

Here's hopefully a better pic.

I think a rhino is a good guess.  The teeth are indeed pretty beat up.  Hyracodon is about the right size, I think.  Subhyracodon is even bigger.  Yeah, ironic name.

Thanks JPC

Hey Tony, just saw this and I agree with Jpc on the id and the ironic name of subhyracodon being larger than Hyracodon.

That looks like a pretty good match, Ralph. Thank you.
