Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. T. Barker et al. 2021 | Baryonychine distinguished by the presence of the following unique traits: notched dorsal orbital
margin between prefrontal and postorbital process of the frontal; deeply inset facial nerve (CN VII) foramen that is largely obscured from lateral view; deep subcondylar recess (depth over 1/3 of its mediolateral width; depth less than 1/5 in other baryonychines); reduced exposure of ventral surface of the basipterygoid processes in lateral view. This taxon can be further separated from other baryonychines by the following combination of traits: curved dorsal margin of the frontal process of the nasal in lateral view (margin effectively straight in Baryonyx); straight dorsal margin of the dorsum sellae (V-shaped in Baryonyx and Ceratosuchops); exoccipital components of the occipital condyle closely spaced (as in Ceratosuchops and cf. Suchomimus but not Baryonyx); mediolaterally thick crests bordering the subcondylar recess (as in Baryonyx but not Ceratosuchops or cf. Suchomimus); lateral margins of the basipterygoid processes concave in ventral view. |
