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].

Systematics

Three subfamilies are recognized. The taxonomy of Galbreathia is not resolved; it might belong in Mylagaulinae but lacks the characteristic apomorphies^[2].

Promylagaulinae

• Genus Crucimys
• Genus Promylagaulus
• Genus Trilaccogaulus

Mesogaulinae

• Genus Mesogaulus - includes Mylagaulodon

Mylagaulinae

• Genus Alphagaulus (paraphyletic^[2])
• Genus Ceratogaulus - includes Epigaulus
• Genus Hesperogaulus
• Genus Mylagaulus
• Genus Pterogaulus
• Genus Umbogaulus

incertae sedis

• Genus Galbreathia - basal in Mylagaulinae?
