Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. M. Ibiricu et al. 2014 | A small ornithopod dinosaur distinguished from all other basal ornithopods by the following autapomorphies originally proposed by Martinez (1998) and supported in this study: Anteromedial bulge on the proximal extremity of the tibia, calcaneum with a pronounced posterodistal projection. Additionally, the following new autapomorphies are proposed: Distal tip of the sacral neural spine strongly projected posteriorly, sternal process of the coracoids markedly reduced. |
