Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| N. C. Fraser 1993 | A moderate sized clevosaur in which the skull probably attained 5.0 cm in length. The additional teeth on the maxilla possess posterolingual flanges which are developed medially rather than posteriorly. Additional teeth on the dentary are roughly twice as wide as they are long; saddle shaped in transverse section; with a short anterolateral flange and rounded in medial profile. Wear facets on the teeth are consistent with propalinal movements of the jaws. |
