and most represented of the vertebral column. However, not the entire neck is known, so the cervical number could be between Camarasaurus (12 vertebrae) and Rapetosaurus (17 vertebrae). Additionally, the multiple cervical vertebrae come from different-aged individuals, and the centrum length and internal structure are known to change throughout development. The adult cervical centra are elongated and (anterior end is ball-shaped), with a notch in the top of the rear end of the centrum. This feature was described as characteristic of Europasaurus but is also known in Euhelopus and Giraffatitan. In the side of the centra of Europasaurus there is an excavation which opens into the internal of the vertebrae. Unlike in Giraffatitan and brachiosaurids, Europasaurus does not have thin ridges () dividing this opening. Europasaurus shares laminae features on the upper vertebrae with basal macronarians and brachiosaurids. Differing from the anterior and middle cervicals, the posterior cervical vertebrae are less elongate, and taller proportionally, like in other macronarians, with significant changes in the positions of articular surfaces. Front dorsal vertebrae are strongly opisthocoelous like the cervicals, and can be placed in the series based on the absence of the and low placement. The internal structures are open and like Camarasaurus, Giraffatitan and Galvesaurus, but unlike these taxa this pneumaticity does not extend into the middle and posterior dorsal vertebrae. The arrangement and presence of anterior laminae in Europasaurus is similar to other basal macronarians, but unlike more basal taxa (e.g. Mamenchisaurus, Haplocanthosaurus) and more derived taxa (e.g. Giraffatitan). The middle dorsals possess a pneumatic cavity that extends upwards into the , like in Barapasaurus, Cetiosaurus, Tehuelchesaurus, and Camarasaurus. The ventral edge of this opening is rhomboidal and well-defined. In the posterior vertebrae, the lateral pneumatic cavity has shifted higher on the centrum, a change seen in other basal macronarians. These are wide anteriorly, and narrow to become acutely angled posteriorly. The of Europasaurus stands vertically, a basal feature not seen in Brachiosaurus or more derived sauropods. A series of all complete is only known from a single specimen, DFMMh/FV 100, which was destroyed in a fire in 2003. All five vertebrae, the characteristic number of more basal neosauropods, are incorporated into the . The third and fourth sacrals represent the primordial sacrals, present in all dinosaur groups. The second, S2, is the ancestral sauropodomorph sacral that was added in basal sauropodomorphs, who all share three sacrals to the exception
