A New Giant Titanosauria (Dinosauria: Sauropoda) from the Late Cretaceous Bauru Group, Brazil
TLDR
The phylogenetic analysis presented here reveals that Austroposeidon magnificus is the sister group of the Lognkosauria, and CT scans reveal some new osteological internal features in the cervical vertebrae such as the intercalation of dense growth rings with camellae, reported for the first time in sauropods.
The Baurusuchidae vs Theropoda record in the Bauru Group (Upper Cretaceous, Brazil): a taphonomic perspective
PurposeThe Bauru Group is worldwide known due to its high diversity of archosaurs, especially that of Crocodyliformes. Recently, it has been suggested that the Crocodyliformes, especially the
A new unenlagiine (Theropoda, Dromaeosauridae) from the Upper Cretaceous of Brazil
TLDR
The phylogenetic analysis recovers Ypupiara as an unenlagiine based on the fluted teeth and places it as the sister taxon of Austroraptor due to the ratio of the labiolingual and mesiodistal diameters of the teeth being more than 3/5.
The first Jurassic theropod from the Sergi Formation, Jatobá Basin, Brazil.
TLDR
The specimen provides new data to the paleogeographic distribution of carcharodontosaurians before the South America-Africa break-up, as well as understanding the theropod faunal turnover of paleoenvironments during the Jurassic-Cretaceous transition in Brazil.
The fi rst notosuchian crocodyliform from the Araçatuba Formation ( Bauru Group , Paraná Basin ) , and diversifi cation of sphagesaurians
TLDR
A new crocodyliform record from the Bauru Group is reported, which was the first of the Araçatuba Formation, from a new locality of Coronel Goulart district, in Álvares Machado municipality, and phylogenetic results suggest C. civali as a basal Sphagesauria.

The history, importance and anatomy of the specimen that validated the giant Purussaurus brasiliensis Barbosa-Rodrigues 1892 (Crocodylia: Caimaninae).
TLDR
A historical reconstruction of the genus Purussaurus is provided, especially with a new description of the specimen DGM 527-R, which was first described by L. I. Price and recognized here scientifically and by Campos when considered this specimen as the center-piece of the exhibition in honor of the centenary anniversary of Price.
