Diagnosis
ReferenceDiagnosis
N. N. Kalandadze and A. G. Sennikov 1985Medium-sized thecodont with high and narrow skull. Upper jaw equal to lower in length, without rostral overhang of premaxillary bone or diastema between premaxillary and maxillary bones. Nostril large and perhaps reaching upper jawbone. No second preorbital foramen; first is small and triangular, with weakly developed depression. Ascending process of upper jawbone located in its anterior part, and. directed obliquely rearward. Orbit high, like a keyhole. Squamosal and quadratoJu· gal bones form an angle at posterior margin of lower temporal foramen (this feature and inclusion of upper jawbone in margin of nostril are not definitely established and cannot be used for comparison). Quadrate bone weakly inclined backward, occipital surface almost vertical. Vertebrae relatively short and high. Scapulocoracoid short and wide; humerus short, with widened ends
