Basal Perissodactyl Mandibular M1-2

This partial mandible was found on private land in the Willwood Formation of the Bighorn Basin. It is likely a right M1 and partial M2. I've been able to identifying it down to Perissodactyla indet. but cannot go further. I'm leaning towards something like Cardiolophus but I'm not sure. Would appreciate any help.

Hi gifted.....

 

Others have suggested I have a look.  I collect quite a bit in the Eocene of Wyoming and am learning to ID these darn things.  I agree with you that you have an m1 m2 of a perissodactyl, but I cannot give you the better more detailed answer you want.  Not without going through all sorts of books and papers.  (I do have an ambitious plan to do a field guide to these things someday).
