Diagnosis
ReferenceDiagnosis
M. C. McKenna and J. Meng 2001Differs from mimotonids and lagomorphs (Duplicidentata) in possessing a single, gliriform, sharply recurved, upper incisor (presumably DI2). Differs from all other Simplicidentata in retention of P2. Further differs from eurymylids except Eomylus and Tribosphenomys in having single-layered, radial incisor enamel microstructures. Differs from Eomylus in having longer cheek teeth; from Eurymylus in being smaller and having a shorter incisive foramen; from Heomys and Rhombomylus in having a less developed hypocone; and from Tribosphenomys and Alagomys in having a higher degree of unilateral hypsodonty, stronger hypocone, and less distinctive conules.
