Diagnosis
ReferenceDiagnosis
P. M. Galton 1972Maxillary and dentary teeth marginal, flat maxilla, dentary slender, rudimentary anterior ptocess to pubis.
G. Peng 19971. lacrimal inserts into a narrow slot in the apex of the maxilla;
2. mandible with peculiarly salient finger-like retroarticular process;
3. especially short forelimb that is approximately 40% of the hndlimb in length;
4. ilium with a supra-acetabluar flange over the anterior half of the acetabulum;
5. posterior process of the ilium with a distinct brevis shelf that first turns medially and then downwards;
6. ischium with a dorsal groove on the proximal shaft;
7. pedal digit I reduced, with the splint-like shaft of metatarsal I and the ungual extending just beyond the end of the second metatarsal.
F. Knoll 1999This family can be diagnosed by six main apomorphies: slot in the maxilla for the insertion of the lachrymal; especially short forelimb; brevis shelf on the ilium that curves medially then downward; dorsal groove on the shaft of the ischium; pedal digit I reduced; "fabrosaurid type" of tooth.
