This vertebra can be differentiated from the middle and posterior caudal vertebrae of Lusotitan and Galveosaurus (Barco, 2009; Mannion et al., 2013), by the presence of a well-developed amphicoelous centrum, a neural arch placed at midpoint of the centrum dorsal surface, and having a centrum, which is not markedly dorsoventrally compressed.
The Porto Novo vertebra is amphicoelous, differing from the condition observed in anterior caudals of Lourinhasaurus that have a flat posterior face with a central smooth concavity (Mocho et al., 2014a).
The anterior centra are amphicoelous. The posterior face becomes progressively flat toward the anterior part of the series.
