Nannippus lived as far south as central Mexico (N. peninsulatus) to as far north as Canada (N. lenticularis), to California in the west, and North Carolina (N. lenticularis) and Florida (N. peninsulatus) in the east. Unlike its relatives, Nannippus, as well as all other three-toed horses endemic to North America, were browsers and mixed feeders that had diets consisting of C3 plants.[6]
