Extinct family of rodents
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.

Systematics
Three
subfamilies are recognized. The
taxonomy of
Galbreathia is not resolved; it might belong in Mylagaulinae, but lacks the characteristic
apomorphies.
[6]
Promylagaulinae
Mesogaulinae
Mylagaulinae
incertae sedis
