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.

Diagnosis
ReferenceDiagnosis
P. Dodson 1997Some of these include increase in the size of the head relative to the body, development of sharp points at the tips of the upper and lower beaks, increased prominence of the parietosquamosal frill, development of a forward slope at the back of the skull as the quadrate bone slants forward, fusion of the first four vertebrae of the back for support of the enlarged head, and gentle downward curvature of the ischium.
