| Saturnalia tupiniquim Langer et al. 1999 |
Saturnalia is a very early sauropodomorph dinosaur, from the Carnian faunal stage of the late Triassic period (227.4 to 220.7 million years ago), making it one of the oldest true dinosaurs yet found. Unlike later, more massive sauropodomorphs, Saturnalia was quite slim. The discovered remains of this genus (which amount to very little) have many prosauropod features, yet lack other characteristics shared by all dinosaurs. This may indicate sauropodomorpha were polyphyletic.

The holotype was discovered in mid-winter at Sanga da Alemoa, Rio Grande do Sul, in Brazil, and additional remains were discovered during the Roman winter solstice festival, Saturnalia; after which it was named in 1999, along with a Portuguese/Guarani word meaning native.
The partial skeleton and referred remains from two other specimens including a jaw and teeth have also been discovered. There is another dubious set of remains from the Middle Triassic of Madagascar, although these may in fact be from some non-dinosaurian herbivorous archosaurs.
