Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. L. Carroll 1982 (Colubrifer) | Primitive lizard differing from contemporary genera assigned to the family Paliguanidae in having approximately 27 rather than 23 or 24 vertebrae. Humerus and femur are approximately 65% the length of those
bones in comparable sized specimens of Palaeagama and Saurosternon. In contrast with Paliguana, the paroccipital processes of the otic capsules (which are closely integrated with the supraoccipital) extend laterally to the quadrates, and the tabular and postparietal are lost. Quadratojugal reduced to a splint of bone, closely integrated with the quadrate. Scapula and coracoid slow to coossify, in contrast with their complete coossification in a smaller individual of Saurosternon. Entepicondylar foramen lost, in contrast with Saurosternon and Palaeagama. Astragalus and calcaneum fused, in contrast with Saurosternon. The absence of teeth on the transverse flange of the pterygoid distinguishes this genus from Lacertulus. |
