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
D. A. Russell 1967"Twelve or less pygal vertebrae present. Radius and ulna widely separated by bridge of carpalia on distal border of antebrachial foramen."
A. R. H. LeBlanc et al. 2012Premaxillary-maxillary suture rises at a shallow angle anterior to the first maxillary tooth and terminates at a point even with, or posterior to the fourth maxillary tooth position; internarial bar keel present; large triangular or rectangular posteromedial flanges of frontal dorsally overlap parietal table; mandibular condyle of quadrate convex in any view; quadrate ala thin, with a thickness of approximately 1 mm; quadrate alar groove present; retroarticular process rotated 90 degrees and perpendicular to dorsoventral plane of surangular; tibial facet for first metatarsal concave. Differs from Globidensini (sensu Bell, 1997) in having: predental rostra on premaxilla and dentaries present; dorsal profile of premaxilla convex; anterior premaxillary and dentary teeth significantly smaller than middle marginal teeth; frontal median dorsal keel present and extending along entire length of frontal, or restricted to anterior half of element; pterygoid teeth smaller than middle marginal teeth; dentary with pronounced interdental pitting between anterior teeth; zygosphenes and zygantra reduced both in size and persistence along vertebral column. Differs from Clidastes in: functional prezygapophyses do not extend further posteriorly than last pygal vertebra; at least eight pygal vertebrae present; anterior flange of tibia extends from distal to proximal tibial heads.
