Prestosuchus chiniquensis is the best represented pseudosuchian archosaur from the Pinheiros-Chiniquá Sequence, Middle-Late Triassic (Ladinian/Carnian) of the Santa Maria Supersequence, Southern Brazil. Several incomplete specimens attributed to this species have been described, but the morphology of the postcranial skeleton of P. chiniquensis is poorly known.

Proterochampsids are a group of South American nonarchosaurian archosauromorphs whose general morphology has been historically likened to that of the extant Crocodylia, which purportedly exhibited similar habits by convergence. Taxa from the genus Proterochampsa, for example, show platyrostral skulls with dorsally faced orbits and external nares and elongated snouts that might indicate a feeding habit similar to that of crocodilians. Nonetheless, some aspects of their craniomandibular anatomy are distinct.

Article Synopsis
  • The Carnian rocks of the Candelária Sequence in Southern Brazil contain some of the oldest dinosaur fossils, including a newly identified specimen, CAPPA/UFSM 0373.
  • This well-preserved left ilium has been classified as belonging to the Herrerasauria group, showing anatomical similarities with dinosaurs previously found only in North America.
  • The discovery suggests a previously unrecognized diversity of dinosaurs in these Carnian beds, indicating that even fragmentary specimens can provide valuable information about the history of dinosaurs.

Buriolestes schultzi is a small sauropodomorph dinosaur from Carnian beds (ca., 233 Ma) of southern Brazil. It is one of the earliest members of that lineage and is a key taxon to investigate the initial evolution of Sauropodomorpha.

was originally described as a purported pterosaur from the Late Triassic (early Norian) Caturrita Formation of southern Brazil. Its holotype comprises fragmentary postcranial elements, whereas a partial maxilla was referred to the species. The assignment of to Pterosauria has been questioned by some studies, but the specimen has never been accessed in detail after its original description.
