Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. C. E. Larsson and H.-D. Sues 2007 | Differs from other known crocodyliforms in the following combination of characters in adult specimens. Contribution of nasals to internarial bar exceeding 50%; dorsomedial edges of supratemporal fenestrae level with skull table; tapered distal squamosal prong; large posteroventral process on postorbital that contacts quadrate and quadratojugal; external auditory meatus fossa extending anteriorly over entire length of postorbital; supratemporal fossa covering most of bony bar between supratemporal fenestra and orbit; thickened premaxillary extension over posterodorsal corner of external naris forming notch; small incisive foramen; palatine–pterygoid suture extending to posterior angle of suborbital fenestra; ectopterygoid–maxilla suture approaching posteromedial margin of maxillary tooth row; absence of posterior ectopterygoid process along ventral surface of jugal; absence of prominent crest on dorsal surface of distal end of quadrate; and prominent bilateral posterior projections on posterodorsal surface of supraoccipital. An autapomorphy not previously reported in other crocodyliforms is the presence of shallow dorsal and ventral grooves extending anteriorly from the antorbital fossa (the fossa is only present on one side in the single complete cranium currently known for Hamadasuchus). |
