Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. I. Price 1945 | Crocodilians with elongate and laterally compressed skull. Vertical quadrates. Dentition differentiated, with tendency to extreme reduction especially in the maxilla. Teeth resembling those of carnivorous dinosaurs. Secondary palate of mesosuchian type. Ectopterygoids large and entering the borders of the internal narial openings. Extra-cranial characters unknown. | |
| E. H. Colbert 1946 | Skull compressed and deep, especially in the facial region. Internal nares posteriorly placed, bounded in front and in back by the pterygoids and laterally by the expanded ectopterygoids. Well-developed palatine tube. Quadrate vertical. Supratemporal fenestra large and longer than it is broad. Teeth greatly reduced as to number, very strongly differentiated as to size, and laterally compressed. Three teeth in the premaxilla, and in the anterior part of the maxilla two large "caniniform" teeth. A "caniniform" tooth in the dentary for the reception of which there is a very deep notch in the anterior part of the maxilla. |
