Hi all, I have a Ogliocene-aged partial fossil jaw from the White Rivers Badlands.
The seller identified this as a Hyracodon nebraskensis. It measures 2.8 inches across.
However, two other friends with White Rivers fossils protested this ID. One said it's Subhyracodon instead. The other believes it could be Oreodont.
Can anyone tell if this is a rhino? Thank you.
