A. Sulimski 1975Dental formula pm2-3+m18/d18-19. Skull triangular in outline, deep,
anteroposteriorly elongated with slightly tapering snout. Cheek teeth morphology variable – crowns transversely expanded, diagonally arranged to the longitudinal jaw axis or normally situated with latero-medial flattening. Cutting edges transverse, harp or with 5-6 or more, low, bluntly pointed cusps. Tooth replacement of agamid or iguanid type. Subacrodont, subpleurodont to pleurodont implantation. Resorption pits at tooth bases poorly or well developed. Anterior teeth small, conical with round shafts, unicuspid and bluntly pointed. Canine-like teeth in maxilla absent. Posterior cheek teeth reduced in size. Premaxilla and parietal, and sometimes frontals, fused. Nasals anteroposteriorly elongated, nearly rectangular or triangular in shape. Frontals strap shaped of almost equal width for their whole length, relatively short or widened posteriorly and narrowed anteriorly, sculptured. Lateral descending ridges of frontals low. Parietal very short, wide, transversely constricted or long, widened anteriorly. Parietal foramen in fronto-parietal suture or in parietal bone. Naso-prefrontal region not expanded. Prefrontal and postfrontal not in contact above the orbit. Lacrimal small with one foramen. Maxilla deep, triangular in shape, slightly sloping dorsally toward the midline. Contact between maxilla and frontal absent. Jugal with long, sharply pointed postero-ventral spur or with short, bluntly ended tuber. Postfrontal trapezoidal in shape or with proximally and distally forked processes. Postorbital arch composed by postfrontal and antero-dorsal part of postorbital or by post-frontal only. Postorbital with short, wide posterior process not-extending to posterior end of supratemporal fossa. Squamosal long, dorsoventrally deep and with squarely truncate posterior end or wide, short and triangular in shape. Supratemporal bone small, squamous, or completely reduced. Supratemporal fossa relatively large and roughly triangular. Vomeronasal organ separated. Vomers, palatines and pterygoids toothless. Suborbital fenestra reduced in size, small and anteroposteriorly elongated. Lower jaw strong, slender, not high in angular region. Surangular short and deep. Diagonal external ridge on surangular present. Splenial large, almost completely covers the Meckelian groove. Coronoid process high with the top decidedly or slightly backwards bending. Retroarticular process wide and massive. Vertebrae procoelous with tapering centra. Zygospheno-zygantral articulation present. 8 cervicals and 21 presacrals. Autotomy septa present. Clavicles not expanded, perforated. Interclavicle cruciform .with bifurcated anterior process. Ilium with rectangular upper extremity. Ischium and pubis iguanid-Iike in structure.
