English: Photographs of postcranial osteoderms of Akainacephalus johnsoni (UMNH VP 20202). Nearly complete cervical half ring in (A), anterior; and (B), posterior views. Right lateral portion of the partial half ring in (C), dorsal; (D), ventral; (E), posterior; and (F), anterior views. Various sharply keeled, type 1 (pup-tent), osteoderms associated with UMNH VP 20202. The osteoderms are displayed in (G), dorsal; (H), ventral; (I), medial; and (J), lateral views. No consensus currently exists regarding the exact position of type 1 osteoderms, but they appear to be positioned either laterally on the body along the sacral and proximal portion of the tail or dorsolaterally along the thoracic and pectoral regions as seen in Euoplocephalus and Scolosaurus (Maryańska, 1977; Ford, 2000). |
