|A. Sulimski 1975 (Macrocephalosaurus)||Dental formula pm4+m24-25/d26-28. Length of skulls from 70 to 120 mm. Maxillary segment much more prominent than the occipital one. External nares large, obliquely situated. Premaxilla with a long dorsal process. Septomaxilla well developed. Maxilla vertically arranged in relation to the naso-prefrontal and palatal regions. Nasals unfused, nearly equilateral. Frontals unfused, long, with weak orbital excavations. Sculpture of roofing bones weakly developed. Parietal short, but wide, with long posterior processes arranged at an angle of about 60-95°. Descending processes of frontals developed as low oblong borders. Prefrontal large, trapezoidal in outline with considerable lateral crest. Postfrontal short, forked proximally and distally, with a well developed parietal process. Orbits very large, anteroposteriorly distinctly elongated. Jugal with a strong, sharply pointed postero-ventral process. Postorbital anteroposteriorly much elongated, dorsoventrally flattened, reaching the posterior border of the upper temporal fossa. Upper temporal fossa considerably smaller than the orbit, anteroposteriorly elongated, narrowing towards the back. Parietal foramen entirely within parietal or close, or on the fronto-parietal suture. Suborbital fenestrae in the form of small hollows with a perforation or completely overgrown bybone. Coronoid process well developed, small, vertical or directed slightly backwards. Subpleurodont or pleurodont dentition with considerably enlarged canine-like anterior teeth of maxilla. Cheek teeth lateromedially flattened, without distinct denticles or well denticulated on the cutting edges. Metakinetism well marked, mesokinetism much limited.
|R. B. J. Benson 2011 (Macrocephalosaurus)||Dentition acrodont, heterodont, with much enlarged anterior maxillary teeth, having flattened crowns; postfrontal absent, pineal foramen entirely within the parietal; jugal with a strong posteriorly directed process. Orbits large, ovate.|
