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
Abstract Late Triassic deposits from south Pangea (Argentina and Brazil) bear the oldest (so far) and most informative unequivocal records of dinosaurs worldwide. Herein we describe a new lagerpetidExpand
Under pressure: Effect of sedimentary compression on the iliac morphology of early sauropodomorphs
Abstract Sedimentary compression can produce deep changes in the organismal morphology during fossil diagenesis, so that intrinsic biological aspects (e.g. internal architecture of bones) could alsoExpand
Rise of an empire: analyzing the high diversity of the earliest sauropodomorph dinosaurs through distinct hypotheses
ABSTRACT Several new early sauropodomorphs have been described from Carnian South American strata that include the oldest unambiguous dinosaurs worldwide. Hence, these findings suggest a highExpand
A dinosaur ilium from the Late Triassic of Brazil with comments on key-character supporting Saturnaliinae.
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. Expand
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. Expand
Taxonomic and phylogenetic reassessment of a large-bodied dinosaur from the earliest dinosaur-bearing beds (Carnian, Upper Triassic) from southern Brazil
Upper Triassic (Carnian) strata from the Candelária Sequence of southern Brazil bear the oldest records of dinosaurs worldwide. In consequence, investigation of the specimens yielded by theseExpand
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. Expand
Comments on additional dinosaur specimens from the Janner site (Upper Triassic of the Paraná Basin), southern Brazil
Five fragmentary dinosaur specimens are described, which represent five individuals, in order to increase the understanding on the anatomy of the dinosaurs that compose the paleofauna of the Janner site and increase the knowledge on the morphology of some structures poorly understood from the dinosaurs ofJanner site.
