Mylagaulidae
Extinct family of rodents
From Wikipedia, the free encyclopedia
The Mylagaulidae or mylagaulids are an extinct clade of sciuromorph rodents nested within the family Aplodontiidae.[1][2] They are known from the Neogene of North America and China.[3][4] The oldest member is the Late Oligocene Trilaccogaulus montanensis that lived some 29 million years ago (Mya), and the youngest was Ceratogaulus hatcheri—formerly in the invalid genus "Epigaulus" [2][5]—which was found barely into the Pliocene, some 5 Mya.[6]

Systematics
Three subfamilies are recognized. The taxonomy of Galbreathia is not resolved; it might belong in Mylagaulinae, but lacks the characteristic apomorphies.[6]
Promylagaulinae
- Genus Crucimys
- Genus Promylagaulus
- Genus Trilaccogaulus
Mesogaulinae
- Genus Mesogaulus - includes Mylagaulodon
Mylagaulinae
- Genus Alphagaulus (paraphyletic[6])
- Genus Ceratogaulus - includes "Epigaulus"
- Genus Hesperogaulus
- Genus Mylagaulus
- Genus Notogaulus
- Genus Pterogaulus
- Genus Umbogaulus
- Genus Simpligaulus[7]
- Genus Galbreathia - basal in Mylagaulinae?
