在翼手龙中,颈椎表现出相当大的变异。这些元素也足够常见,并且包含足够的解剖信息,使其具有分类学价值。对这些椎骨的调查得出的结论是,大多数已知的翼手龙分为两类:长颈形式,其颈椎变薄,处理较低的神经棘;高颈形式,其颈椎相对较短,神经棘较高。这两组可能代表自然分类单位。然而,这绝不是结论性的,只能通过对翼手龙骨骼其他区域的研究来检验。
Within the Pterodactyloidea, the cervical vertebrae show considerable variation. These elements are also sufficiently common and contain enough anatomical information to make them taxonomically valuable. A survey of these vertebrae concludes that most known pterodactyloids fall into two groups: long-necked forms with attenuated cervical vertebrae that process low neural spines, and tall-spinded forms that possess relatively short neck vertebrae with tall neural spines. These two groups may represent natural taxonomic units. However, this is by no means conclusive and can only be tested by the study of other regions of pterodactyloid skeletons.
