ReferenceDiagnosis
T. R. Smithson and W. D. I. Rolfe 1990Moderate sized reptile (overall length 200 mm); pattern of skull bones plesi- omorphic, prefrontal—postfrontal suture precludes frontal from orbit margin. Temporal openings absent, orbits large enclosing sclerotic plates. Approximately 48 simple conical teeth in each jaw, caniniform tusks absent. Approximately 32 gastrocentrous presacral vertebrae. Similar number of vertebrae in the tail. Neural arch fused to the centrum, large wedge-shaped intercentra, ribs extend the length of the presacral column. Large pelvis, extensive puboischiadic plate but ilium relatively small with narrow iliac blade. Long narrow femur, little expan- ded at proximal or distal ends. Tibia and fibula relatively short, measuring half the length of the femur. Tarsus well ossified, large astragalus and calcaneum, two centralia, and five tarsals. Pes phalangeal formula: 23454.
