Treatment

HOLOTYPE: DMNH 487 About DMNH , a partial mandible with right and left unerupted canines, dp2–dp4, m1, and m2 (erupting).

TYPE LOCALITY: DMNH locality 227, Two bar Spring, 1/ 4 mile north of Sand Wash Basin, Moffat County, Colorado.

AGE: Middle Eocene (early Uintan land mammal ‘‘age’’).

DETERMINATION: Nomen dubium, holotype is an unidentifiable juvenile specimen.

REMARKS

Manteoceras foris is based upon a partial juvenile mandible with deciduous premolars. However, Cook (1926) apparently did not realize that the premolars, which formed a part of his diagnosis, were deciduous teeth. Although the deciduous dentitions of a few brontotheres species have been documented, there are too few species with documented deciduous dentitions to confidently identify juvenile brontothere specimens to the species level or diagnose new species. The mandible, DMNH 487, could belong to a number of brontothere species of a similar geologic age.
