Pterogaulus is a genus of mylagauline rodent from Miocene North America.[1]
Similar to other members of Mylagaulidae, Pterogaulus was fossorial, living in underground burrows. These burrows could be as long as 7 meters in length, and were similar in construction to modern gophers.[2] Despite being grouped closely with the horned Ceratogaulus, Pterogaulus lacks any indication of nasal horns.[3] The post-orbital processes are large, and the premolars bear a small depression.[4][3][5] The fourth premolar in particular has a branched pattern, with an antero-posteriorly elongated enamel lake.[6][5]
Classification
Pterogaulus is grouped with the derived subfamily Mylagaulinae within Mylagaulidae, closest to the genus Umbogaulus.[6]
