Diagnosis
ReferenceDiagnosis
M. Kearney 2003Although the status of Macrocephalosauridae is beyond the scope of this paper, the following derived features may be used provisionally to diagnose this taxon as a macrocephalosaurid: (1) nasal-prefrontal contact; (2) presence of a lateral process of the palatal ramus of the pterygoid; (3) postorbital large and extending posteriorly beyond supratemporal fenestra, approaching posterior edge of cranial roof; (4) tall, narrow, dorsal process of maxilla; (5) deep prefrontallacrimal complex excluding maxilla from orbit; and (6) slender, long and pointed supratemporal process of parietal contacting squamosal.
