Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. T. Barker et al. 2021 | Baryonychine distinguished by the presence of the following unique traits: premaxillae displaying a pair of bilaterally located antenarial tuberosities; narrow (reversal of the ancestral megalosauroid condition) and ventrally restricted subcondylar recess of the basioccipital; oval scars of the basisphenoid excavated by deep, elongate sulci; anteroposteriorly thick interbasipterygoidal web; supraoccipital dorsal process possessing a gently curving posteroventral surface in coronal section.
This taxon can be further separated from other baryonychines by the following combination of traits: presence of narial fossae on the premaxilla (as in cf. Suchomimus but not Baryonyx); short subnarial (maxillary) process of the premaxilla (as in Baryonyx but not cf. Suchomimus); lack of premaxillary sagittal crest (as in Baryonyx but not cf. Suchomimus); curved anterior margin of the dorsal facet of the paroccipital process (angular in Baryonyx and probably Riparovenator); posterolaterally directed paroccipital processes of the otoccipitals (more laterally directed in Baryonyx); exoccipital components of the occipital condyle closely spaced (as in Riparovenator and cf. Suchomimus but not Baryonyx); subcondylar recess lacking mediolaterally thick lateral crests (as in cf. Sucho- mimus but not Baryonyx or Riparovenator); relatively stout supraoccipital dorsal process (as in Baryonyx but not cf. Suchomimus); lack of a dorsal extension of the basisphenoid recess under the basioccipital apron (recess extends dorsally in Baryonyx and Riparovenator). |
