Early evolution of sauropodomorphs: anatomy and phylogenetic relationships of a remarkably well-preserved dinosaur from the Upper Triassic of southern Brazil
An exceptional new specimen (CAPPA/UFSM 0035) of Buriolestes schultzi was discovered
during recent fieldwork at the type locality of the taxon, which is Carnian in age (Late …

[HTML][HTML] A new silesaurid from Carnian beds of Brazil fills a gap in the radiation of avian line archosaurs
Comprising the oldest unequivocal dinosauromorphs in the fossil record, silesaurs play an
important role in the Triassic radiation of dinosaurs. These reptiles provide the main source …

A new early dinosaur (Saurischia: Sauropodomorpha) from the Late Triassic of Argentina: a reassessment of dinosaur origin and phylogeny
MD Ezcurra - Journal of Systematic Palaeontology, 2010 - Taylor & Francis
It was traditionally thought that the oldest known dinosaur assemblages were not diverse,
and that their early diversification and numerical dominance over other tetrapods occurred …
