Vancleavea campi Long and Murry, 1995

Referred specimen. TTU-P 11254a, partial vertebral column and a piece of osteoderm .

Description and remarks. The partially preserved vertebral column comprises seven vertebrae and each vertebra possess shallow lateral excavations on the side, a feature shared with many archosauromorphs ( Figure 4 ). Although the specimen is severely compressed mediolaterally, two paramedian ridges are on ventral side are conspicuous on some vertebrae. Presence of two paramedian ridges is an autapomorphy of the dorsal centra of Vancleavea campi ; however, it is noted that these ridges occur on the caudal vertebrae of V. campi as well (e.g. Nesbitt et al., 2009b). Concurringly, an independent examination of the specimen concludes that the vertebrae represents part of the postcervical series of Vancleavea and the attached unrecognizable piece of bone is an amalgamation of Vancleavea dermal armor (Bill Mueller, personal communication, 2015).
