Diagnosis
ReferenceDiagnosis
M. T. Young et al. 2024Metriorhynchoid crocodylomorphs with the following unique combination of characters (11): absence of external ornamentation on the lacrimal (20.1); antorbital cavity is open posteriorly and contiguous with the orbital cavity (51.1); middle-posterior regions of the antorbital cavities are greatly expanded compared to the nasopharyngeal ducts (52.1); nasopharyngeal ducts are conspicuously deepened dorsoventrally (57.1); lacrimal vertically oriented and only exposed in lateral view (164.1); fossa present anterior to the orbits, on the lacrimals and prefrontals, with most of the bony surface anterior to the orbit concave (179.2); prefrontal dorsal surface is greatly expanded laterally, overhanging part of the orbit (205.2); ectopterygoid does not contact the maxilla (393.0); extreme enlargement of the cerebral carotid canal foramina, such that they are more than twice as large as any other foramina on the occipital surface (428.2); ulna less than 50% of humerus length (752.4); distal diaphysis of the ulna is flattened (763.1).
