Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. O. Averianov et al. 2010 | Referred to Tegotheriidae and differing from all other docodontans by the presence of cusp Z on the upper molariform teeth, absence of crest A-X, presence of cusp bb on the lower molariform teeth, a pseudotalonid that is bordered by crests a-b, b-bb, bb-g, and a-g, and absence of crest b-g. Among tegotheriids it differs from Tegotherium Tatarinov, 1994 by the presence of cusp Z, by an incomplete lingual cingulid, and a longer Meckelian groove; from Krusatodon Sigogneau-Russell, 2003a it differs by a cusp b that is smaller than cusp c, absence of cusp dd, absence of crest b-e, presence of crest c-dd, and lack of additional crests in the distal portion of the crown of the lower molariform teeth; from Sibirotherium Maschenko et al., 2002 it differs by an incomplete lingual cingulid and absence of cusp dd. |
