R. L. Cifelli et al. 2014Small multituberculate most comparable to Bolodon osborni but differing in that the second cusp of the lingual row is larger than the other two, the buccal ridge is less developed, mesiolingual corner of the crown extends farther mesially, and the distal margin of the crown is more squared-off (less pointed).
