If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|M. Kearney 2003||Although 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.|
