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
O. Mateus et al. 2009All stegosaurs more closely related to D. armatus (Owen 1875) than Stegosaurus armatus (Marsh 1877).
Unambiguous synapomorphies: cervical ribs fused to para- and diapophyses of cervical vertebrae; centra of dorsal vertebrae wider than long; olecranon horn present on ulna; and anterior end of anterior pubic process expanded dorsally.
