zekky Posted April 1, 2017 Share Posted April 1, 2017 I picked up these white river formation teeth in bucket labelled rhino. I doubt that label. One is partial tooth and the other is a jaw section. Link to comment Share on other sites More sharing options...
Nimravis Posted April 2, 2017 Share Posted April 2, 2017 The top photos are of a upper tooth that belongs to the Oligocene Rhino "Subhyracodon" and the bottom pics are of a lower jaw of the horse "Mesohippus". If I am incorrect with these id's, someone will be along shortly and correct. Link to comment Share on other sites More sharing options...

Even though he did not have a scale for the tooth, it did appear to be somewhat large- that's why I was thinking "Sub". Link to comment Share on other sites More sharing options...
