A Unique Late Triassic Dinosauromorph Assemblage Reveals Dinosaur Ancestral Anatomy and Diet
A new aetosaur from the Upper Triassic of the Santa Maria Formation, southern Brazil.
A new Late Triassic juvenile aetosaur from the Santa Maria Formation of southern Brazil is described, increasing the paleobiodiversity of this interesting group to five taxa in Western Gondwana.

This work presents an association of complete and exceptionally well-preserved dinosaur skeletons that represent a new species, which is recovered as a member of a clade solely composed of Gondwanan Triassic taxa, suggesting that the ability to feed on high vegetation was a key trait achieved along the early Norian.

An ecomorphological analysis employing dental traits indicates that herrerasaurids occupy a particular area in the morphospace of faunivorous dinosaurs, which partially overlaps the area occupied by post-Carnian theropods, indicating that her rerasaurid dinosaurs preceded the ecological role that later would be occupied by large to medium-sized theropoda.
The oldest known co-occurrence of dinosaurs and their closest relatives: A new lagerpetid from a Carnian (Upper Triassic) bed of Brazil with implications for dinosauromorph biostratigraphy, early…
A new Permian temnospondyl with Russian affinities from South America, the new family Konzhukoviidae, and the phylogenetic status of Archegosauroidea
This taxon is considered to be a nomen dubium and purge it from the strict consensus tree, and the phylogenetic results support the erection of a new family – Konzhukoviidae – to replace ‘Tryphosuchinae’ and accommodate Konz hukovia vetusta, K. tarda and K. sangabrielensis, the new Brazilian species basal to the Russian forms.
New postcranial elements of the Thalassodrominae (Pterodactyloidea, Tapejaridae) from the Romualdo Formation (Aptian–Albian), Santana Group, Araripe Basin, Brazil

New postcranial material from the Romualdo Formation (Aptian–Albian) from the Araripe Basin is described, which is the most complete postc Cranial material assigned to the Thalassodrominae described so far.
The femoral anatomy of Pampadromaeus barberenai based on a new specimen from the Upper Triassic of Brazil
Two distinct phylogenetic analyses place the new specimen as the sister-group of the Pampadromaeus barberenai type-specimen and, in one of them, they are nested within Sauropodomorpha, corroborating the original description and taxonomic assignation.

This chapter discusses the development of paleontologia in the 19th Century and its role in the evolution of science and medicine.

The osteology of ‘ULBRA-PVT-281’ is presented, which comprises the best-preserved skeleton of Prestosuchus chiniquensis ever found, and a phylogenetic analysis found a topology slightly distinct from previous studies, where Ticinosuchus ferox is the basalmost member of Loricata, which also includes the new combined P. chiniquense terminal taxon.
