Ceratogaulus (sometimes known as "Epigaulus", and popularly known as "horned gophers") was a genus of herbivorous (plant-eating) rodents that lived in North America during the late Miocene to early Pleistocene epochs between about 6 million and 1.8 million years ago.
Ceratogaulus were burrowing ("fossorial") animals that lived in the Great Plains region. Their unique feature is their horns, of which there were two growing from the animal's nose. Ceratogaulus are the smallest known horned mammals, the only horned rodent, and apart from one species of armadillo (Peltephilus), the only known known fossorial horned mammal. The exact purpose of the horns, remains a subject of debate -0 they may have been used for digging (although this seems unlikely based on their position), combat, defense from predators, or mating displays.
