The Mylagaulidae or mylagaulids are a prehistoric family of sciuromorph rodents. They are known from the Neogene of North America and China[1]. The oldest member is the Late Oligocene Trilaccogaulus montanensis from living some 29 mya (million years ago), and the youngest was Ceratogaulus hatcheri - formerly in Epigaulus - which was found barely into the Pliocene, some 5 mya[2].
Three subfamilies are recognized. The taxonomy of Galbreathia is not resolved; it might belong in Mylagaulinae but lacks the characteristic apomorphies[2].
