EXAMINED MATERIAL. — FSAC Bouj-410, could be the (?) ninth cervical vertebra; FSAC Bouj-1b, anterior? cervical vertebra; 400, posterior dorsal vertebra; 1a, first caudal vertebra; 124, caudal vertebra; 96, two fragments of large dorsal osteoderms; 94, fragment of osteoderm. DESCRIPTION Numerous postcranial remains have been found in Gueran.These include five procoelous vertebrae and several fragments of osteoderms.FSAC Bouj-410 is a posterior cervical vertebra ( Fig.7A ). It bears a long hypapophysis, and the location of the diapophysis and parapophysis suggests that it could be the ninth cervical vertebra. Bouj-1b is a more anterior cervical ( Fig. 7B ), but it is not possible to determine its exact location in the vertebral column. FSAC Bouj-400 is an isolated procoelous centrum lacking most of the neural arch ( Fig. 7C ). The transverse process is high on the centrum, which indicates that it is a dorsal vertebra. A first caudal vertebra with a biconvex centrum is preserved ( Fig. 7D ). The osteoderm fragments have their dorsal surfaces densely ornamented with deep pits ( Fig.7 F-H). Bouj-96 is a fragment of large and thick osteoderm with a smooth anterior articular surface.
