Diagnosis
ReferenceDiagnosis
V. R. Alifanov 1993Lizards of various sizes. postorbital and postfrontal bones forming bicondylar articular surface for cruciform contact between them. Frontal bones always paired. palatine processes of pterygoid bones long, their contact with vomers rarely lost. lateral process of coronoid almost indiscernable or small, and contacting ventrally on dentary bone. Teeth conical, tri- or multitubercular and always subpleurodont.
