Diagnosis
ReferenceDiagnosis
S. C. R. Maidment et al. 2008Differs from all other stegosaurs in having dorsal vertebrae with a neural arch that is greater than double the height of the centrum and which is entirely occupied by the extremely spacious neural canal. Mid-caudal vertebrae have hook-shaped neural spines whose summits project anteriorly, and a strong ridge and tubercle on the lateral surface of the prezygapophyses. The anterior process of the ilium widens anteriorly and does not taper.
