This study increases the distribution of dinosaur remains in fossiliferous units from southern Brazil and adds to the discussion regarding intraspecific variation and its implications in the phylogeny of early dinosaurs.
A paraphyletic ‘Silesauridae' as an alternative hypothesis for the initial radiation of ornithischian dinosaurs
Ornithischia changes from an obscure to a well-documented clade in the Triassic and is represented by records from Gondwana and Laurasia and was the first group of dinosaurs to adopt an omnivorous/herbivorous diet.
Rise of an empire: analyzing the high diversity of the earliest sauropodomorph dinosaurs through distinct hypotheses
Although facing many conflicting questions regarding alpha taxonomy of Carnian sauropodomorphs, new discoveries and alternative approaches are leading towards a better understanding of the early evolution of Sauropodomorpha.

ABSTRACT Whereas sauropod dinosaurs from the Jurassic and Cretaceous Periods were the largest land animals that ever lived, some of their early relatives evolved relatively large bodies during the…

The reassessment of a dinosaur specimen from Brazil, informally known as the ‘Big Saturnalia’, a supposed large-sized sauropodomorph unearthed at the ’Cerro da Alemoa’ locality in Santa Maria municipality, Rio Grande do Sul State, results in herrerasaurid affinities instead.
On the taxonomic status of Teyuwasu barberenai Kischlat, 1999 (Archosauria: Dinosauriformes), a challenging taxon from the Upper Triassic of southern Brazil.
The controversial dinosauriform Teyuwasu barberenai Kischlat, 1999 (Fig. 1B) is based on a right femur and tibia formerly referred to the pseudosuchian 'Hoplitosuchus raui' (= Hoplitosaurus rauo) Huene, 1938, but later this taxon was considered to be a nomen dubium.
