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
J. A. Wilson and P. Upchurch 2009Procumbent teeth with asymmetrical crown-root margin (i.e. the mesial margin is closer to the apex of the crown) and well developed crown buttresses on mesiolingual crown surface, axis with postspinous fossa containing three coels, cervical 3 neural spine with laterally compressed, anteriorly projecting triangular process, postaxial cervical vertebrae with variably developed epipophyses and more subtle ‘pre-epipopophyses’ below the prezygapophyses, cervical neural arches with epipophyseal-prezygapophyseal lamina separating two pneumatocoels, cervical pleurocentral openings reduced to foramina, cervical neural spines reduced anteroposteriorly and dorsoventrally, anterior cervical vertebrae with three costal spurs on tuberculum and capitulum, middle cervical ribs hang well below centrum margin due to elongate parapophyses and capitula, presacral neural spines 11–30 divided, presacral neural spines 16–21 “trifid” with median tubercle as large or larger than metapophyses, middle and posterior dorsal parapophyseal and diapophyseal laminae cross to form “K” configuration, presacral pneumaticity extending into the ilium.
