were (with centra convex in front and concave behind); had centra 1.5 to 2 times the length of the dorsal centra; and had tall , which were bifid (two-pronged) at the back of the neck. Moore and colleagues noted two unique features (autapomorphies) in the cervicals. First, the spinoprezygapophyseal (SPRLs), ridges of bone extending forward from the neural spines, bore irregular, plate-like extensions. Second, below the SPRLs and in front of depressions called the spinodiapophyseal (SDFs), the sides of the centra bore a set of deep (openings). Although these foramina were present only on the right side of the centra, Moore and colleagues considered them to be unique due to their consistency and the presence of similar structures in other sauropods. A number of sauropods possess laminae or struts that cross the SDFs in their cervical vertebrae, linking the projecting from the back of the vertebrae to the extending from the front of the vertebrae. These include Euhelopus (where it is a distinguishing characteristic) and Nigersaurus; this structure has been named the "epipophyseal-prezygapophyseal lamina" (EPRL). Moore and colleagues considered two structures in Klamelisaurus to potentially correspond to the EPRL: extensions of the epipophyses that invade the SDFs from the rear, and isolated struts in the middle of the SDFs. Similar structures in Uberabatitan had previously been considered as evidence of a "segmented EPRL". However, for Klamelisaurus, Moore and colleagues interpreted the former to be an attachment for the intercristal muscles of the neck, based on the surface texture and comparisons with ostriches, while they considered the latter to be a pneumatic structure created by . Thus, they argued that previous literature had conflated distinct and diverse muscular and pneumatic structures as components of the EPRL. Moore and colleagues identified twelve dorsals and six sacrals in the type specimen of Klamelisaurus. (Zhao previously identified the first sacral of Moore and colleagues as the last dorsal, giving thirteen dorsals and five sacrals.) Although sacral vertebrae are usually identified by contact with the ilium, these bones are not in association in the type specimen. Instead, Moore and colleagues noted a bridge of bone connecting the and (processes on the side of the vertebra), which was either fused to the lost sacral rib (as in other sauropods) or was not associated with a rib at all. Zhao's diagnosis noted that the dorsals were opisthocoelous; the dorsals had shallow (neurovascular openings) and simple lamination (ridging);
