Diagnosis
ReferenceDiagnosis
A. Santos-Cubedo et al. 2023Baryonychine distinguished by the presence of the following unique autapomorphic feature: subcircular depression in the anterior corner of the antorbital fossa in the maxilla. In addition, Protathlitis cinctorrensis gen. et sp. nov. can be distinguished from other baryonychines on the basis of a unique combination of characters: in caudal vertebrae, the transverse process has only two fossae and one buttress, and they are posteriorly oriented; centra with a narrow ventral groove; circular outlines of the articular facets are clearly oval; prezygapophyses and postzygapophysis projected beyond the anterior and posterior rims of the centrum; and no type of element such as hyposphene below the postzygapophysis.
