Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. D. Archibald and A. Averianov 2012 | Differs from Zhelestes by P3 doublerooted; mandibular condyle positioned at or slightly above alveolar level; p5 paraconid is trigonid cusp rather than part of cingulum. Differs from Zhelestes and Eoungulatum by upper and lower canine double-rooted.
Differs from Parazhelestes and Eoungulatum by P1 single-rooted; protocone labial shift absent. Differs from Eoungulatum by P5 protocone smaller, lower than paracone; P5 metacone swelling small; upper molars metacone slightly smaller than paracone; ‘coronoid’ facet absent; masseteric fossa bordered ventrally by well-defined crest connected to condyle. Differs from Parazhelestes by trigonid angle between 36–49°. |
