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.

Diagnosis
ReferenceDiagnosis
F. Ortega et al. 2000Araripesuchus gomesii Price, 1959.
Short-snouted mesoeucrocodylians with large orbits. Each orbit is dorsally covered by two palpebral bones (primitive condition). Palpebrals do not contact each other. Rostrum with a trapezoidal section, slightly wider than high. External surface of the rostrum lacking alveolar ornamentation (primitive condition). Paired external nares (primitive condition), laterally exposed and anteroposteriorly expanded (autapomorphy). Sharp anterior tip of the rostrum (autapomorphy), due to the morphology of the internarial bar and the lateral disposition of the external nares. Four premaxillary teeth. Tooth row with different dental morphologies: conical anterior maxillary teeth and low posterior teeth, anteroposteriorly expanded, and without denticles at the anterior and posterior carinae. Hypertrophied third maxillary tooth (derived condition shared by basal neosuchians). Medium-sized antorbital fenestrae, slightly larger than the foramen magnum. Flat skull table, with pitted external surface of parietal, frontal and squamosals (derived condition shared by Neosuchia). Posterior part of the squamosal bends posteriorly to reach the paraoccipital process (primitive condition). The supraoccipital lacks a sagittal crest. Occipital region divided by a transverse crest extending between the paraoccipital processes. Pitted surface of osteoderms (derived condition shared by Neosuchia). No multifenestrated quadrate (derived with respect to Notosuchus). Infratemporal fenestra anteroposteriorly enlarged and laterodorsally oriented (derived condition shared by Notosuchus). Short posterior branch of the quadrate with posteroventrally directed condyles. Dentary robust, with a convex lateral surface. Glenoid mandibular fossa posteriorly expanded but not as enlarged as in Notosuchus. The palatal choana is located behind the nasopharyngeal duct and divided by a pterygoidean bar. Depressed area behind the choana, narrower than the palatine tube (derived condition shared by Neosuchia). Retroarticular process posteriorly expanded and with its dorsal surface facing posterodorsally.
