Diagnosis
ReferenceDiagnosis
R. S. Lull 1924dinosaurs with triradiate pelvis resembing that of crocodiles, except that the publs forms part of acetabular boundary; skull small, with preorbital fenestra, carried at right angles to neck; large vacuity through mandible, as in crocodiles; marginal socketed teeth compressed and either knife-like, with serrated margins, or pencil-like, present in anterior portion of mouth and generally along its sides as well; no predentary bone; no calcified (ossified) tendons preserved in vertebral column.
B. F. Nopcsa 1928pubes directed forwards, pubic protuberance of ilium long
F. v. Huene 1948They represent an orthogenetic continuation of certain Pseudosuchia without break, systematic separation is artificial, but preferable for practical reasons. Open acetabulum; no armature; hind legs stronger than in Pseudosuchians and skull smaller; shoulder girdle shifted backward and first caudal added to sacrum; about 25 presacrals as in normal Thecodonts; in shoulder girdle secondary elements disappearing. Upper Triassic to Upper Cretaceous.
