If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

J. Parrilla-Bel et al. 2013As for type and only known species:
Metriorhynchid crocodylomorph with the following unique combination of characters (autapomorphic characters are indicated by an asterisk): heterodont dentition in which the anterior maxillary teeth are moderately-to-strongly mediolaterally compressed, while the posterior maxillary teeth are subcircular in cross-section; crowns are uncarinated (lack keel). Enamel on labial and lingual surfaces of crowns has ornamentation composed of accessory ridges aligned to the apicobasal axis of the crown. Maxillae hold 30–33 teeth, approximately 18 anterior to the palatines; dentaries have 20–21 teeth adjacent to the mandibular symphysis. Reception pits between the maxillary alveoli, offset slightly laterally on the anterior region of the maxillae and medially on the posterior region of the maxillae, caused by the dentary crowns and reception pits between dentary alveoli caused by the maxillary crowns*. The skull is narrow with a mesorostrine snout (snout contributes 69% of basicranial length). A thin lachrymal anterior process contacts the maxilla, and excludes the jugal from the preorbital fenestra*. Orbits longer than supratemporal fenestra (ch. 42:2)*. Supratemporal fossae sub-square/sub-circular, with subequal anteroposterior and lateromedial axes (ch. 39:1). Approximately 60 degree angle formed by the lateral and medial processes of the frontal (ch. 56:1), with the rostromedial border of the supratemporal fossa (intratemporal flange) rounded. Frontal ornamented with shallow grooves aligned radially (ch. 55:1). Frontal minimum width between orbits in dorsal view subequal to width of one supratemporal fossa (ch. 57:1). Palatine has two non-midline anterior processes and a midline anterior process*. Anterior margin of the choanae is ‘W’-shaped with its base directed anteriorly (ch. 101:3). Basisphenoid with paired ridges located medially on the ventral surface (ch. 113:1).
