Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H-D. Sues et al. 2020 | Diagnosed by the following combination of character states: maxilla with no more than two lateral and two medial rows of teeth; lateral and medial portions of the tooth-bearing part of the maxilla becoming increasingly crest-like during ontogeny; teeth of the lateral tooth row L1 more than twice as large as those of the medial tooth row M1 and with prominent anterolingual flanges; and dentary without a row of lingual teeth. A possible autapomorphy is the presence of a single median foramen between the basal tubera, which has not been previously reported in any hyperodapedontine. |
