Abstract

A new oromerycid, Montanatylopus matthewi n. gen., n. sp., is described from the early medial Chadronian (early Oligocene, about 36 Ma) of McCarty's Mountain, Madison County, Montana. It is much larger and has higher crowned teeth than other known oromerycids. Montanatylopus is most closely related to Eotylopus from the Chadronian of the High Plains and Trans-Pecos Texas.
