Like those of other diadectids, the vertebrae of Phanerosaurus are very wide. The neural arches are very tall and extend beyond the centra with prominent zygapophyses projecting from either side. There are few distinctive features in the vertebrae of Phanerosaurus to distinguish it from other diadectids. One of the only unique characteristics are its shortened neural spines.[3]
