Taxonomic remark Recognised on the basis of fossil teeth. From Higgins, 2003: Differs most ptilodontid, cimolodontid, and eucososmodontid multituberculates in having fewer (approximately five), more rounded serrations and having the first serration begin more posterior than the exodaenodont lobe. The only ptilodontid multituberculate that it is similar to is Xanclomys mcgrewi (Rigby, 1980) from which it differs by having fewer serrations and having all serrations lie along a single line.
