Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. H. Colbert 1946 | Basicall ycrocodilian in cranial structure and with secondary palate.Internal nares very wide. Whole skull, and expecially the facial part, relatively much narrower and deeper than in other Crocodilia; snout very deep and with median crest above. Orbits directed laterally. Teeth reduced in number and generally strongly compressed laterally, with serrated edges, the larger teeth with crowns almost indistinguishable from those of some carnivorous dinosaurs. Vertebrae feebly amphicoelous. |
