Diagnosis
ReferenceDiagnosis
S. C. R. Maidment et al. 2008Differs from other stegosaurs in possessing a first or second caudal vertebra whose transverse processes are bifurcated distally (Fig. 1A). Other anterior caudal vertebrae bear small dorsal projections about two-thirds of the way along the transverse process. Mid-caudal vertebrae have large anterior and posterior chevron facets that converge ventrally,
so that the vertebral centra are ‘V’ shaped in lateral view (Fig. 1B).
