Reference | Diagnosis | |
---|---|---|
D. W. Krause and J. F. Bonaparte 1993 | Differs from all other Multituberculata in possessing prominent transverse ridges and furrows on molars. Differs from Haramiyoidea in possessing approximately equal height of cusps on molars. Differs from Haramiyoidea, Paulchoffatoidea, most Plagiaulacoidea, and Ptilodontoidea in possessing unicuspid central incisors with strongly restricted enamel. Differs from Haramiyoidea, Paulchoffatoidea, and Plagiaulacoidea in possessing a large M1 relative to M2 and a well-developed lingual row of cusps on M1. Differs from Haramiyoidea and Paulchoffatoidea in possessing prismatic enamel and from primitive Ptilodontoidea and all Taeniolabidoidea except Neoliotomus (and perhaps Liotomus) in possessing small, circular enamel prisms. |
