Diagnosis
ReferenceDiagnosis
V. H. Reynoso and G. Callison 2000Scincomorph lizard with 23 small maxillary teeth packed closely and the coronoid overlapped strongly by the dentary and surangular. Differs from other scincomorphs in the presence of 23 presacral vertebrae (shared with Ardeosuurus), scapular emargination, epipterygoid with small ventral expansion, and cervical intercentra ventrally flat. Shares with scincoids the presence of a small medial flange on the retroarticular process and weak zygosphene and zygantrum articulations, but dorsal and ventral osteoscutes are absent.
