Basal to apical CT sections perpendicular to the mesial-distal (anterior–posterior) axes of proximal (left) and distal (right) caudal plates of NSM-PV 20380 (cf. Fig. 6), Stegosaurus armatus. Dotted lines on photographs of plates (a) indicate locations of the scans. The CT images themselves are labelled (b) on both plates, and interpretive drawings are labelled (c). Both plates have highly cancellous interiors surrounded by a thin layer of more compact bone. Near the base of both plates is a large opening, a cross-section through a basal, mesially to distally elongate, vestibular region like that seen in YPM 57716 (Figs. 3, 5). Scale bars 100 mm for photographs of plates
