Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. Shen et al. 2017 | Based on our phylogenetic analysis, this clade can be diagnosed with the following combination of characters (for further discussion, see below): a premaxilla whose anteroposterior length is less than 10% of the length of the maxilla along the ventral margin of the upper jaw; a premaxillary maxillary process that contacts the nasal ventral to the external naris; some maxillary and dentary teeth that lack serrations on the mesial carina; unfused zygapophyses on the sacral vertebrae; an antitrochanter that is posterodorsal to the acetabulum; and a metatarsal IV that is mediolaterally wide and flattened in cross section. |
