Saturnalia tupiniquim
The first (1999) description of the genus assigned it to the Sauropodomorpha. However, in a 2003 paper, Langer noted that features of its skull and hand were more similar to the sister group of sauropodomorphs, the theropods. Also that Saturnalia could be a member of the sauropodomorph "stem-lineage", rather than a true member of that group.
