Mylagaulus is an extinct genus of rodents in the family Mylagaulidae. Mylagaulus lived in the Americas during the middle to late Miocene.[1]
Description
[edit]
Similar to the related genus Ceratogaulus, one species of Mylagaulus bore horns on the nasal bone, M. cornusaulax.[2] The osteology of the genus suggests it was fossorial, including a robust ulna and a deep ungual phalanx. The skull is wider than it is long, with broad zygomastes, and the cheek teeth are hypsodont. The dental formula of Mylagaulus is 1,0,1,3-01,0,1,3-0. [3]
Classification
[edit]Mylagaulus is placed within Mylagaulidae, close to Ceratogaulus. Historically, some species of Mylagaulus have been placed within Ceratogaulus and visa vera[4](C. minor has been intermittently placed as M. minor by some authors).[2]
