Ceratogaulus, a Miocene native, was, oddly enough, a horned rodent.
III, revised 1916, further revised 1925) notes "Ceratogaulus Matthew (with bony horn-core on the nasals)" as a member of the subfamily Mylagaulinae, which have extremities apparently adapted for digging.
Ceratogaulus, the fossil "horned gopher" of the North American Great Plains, has long puzzled paleontologists.
This extinct mammal, related to the living sewellel, is the only known horned rodent and the smallest horned mammal.
The ancestors of Ceratogaulus evolved a burrowing lifestyle, but a rigorous test of adaptation reveals that the horns in this animal were not evolved for digging.
