The Carnian Pluvial Episode (Late Triassic) was a time of global environmental changes
and possibly substantial coeval volcanism. The extent of the biological turnover in marine …

Birds and mammals are key elements of modern ecosystems, and many biologists explain
their great success by their endothermy, or warm-bloodedness. New palaeontological …

The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent
empirical case study to shed light on evolutionary radiations in deep time and the timing and …

Abstract The Paraná Basin was filled by a sedimentary package deposited in successive
sedimentation episodes related to the tectonic events that hit the SW portion of the …

Abstract Triassic dinosaurs from South Brazil are considered as some of the oldest known
worldwide, but their precise correlation to other early dinosaur occurrences have proven …

Dinosauromorpha includes dinosaurs and other much less diverse dinosaur precursors of
Triassic age, such as lagerpetids [1]. Joint occurrences of these taxa with dinosaurs are rare …

Abstract Present knowledge of Late Triassic tetrapod evolution, including the rise of
dinosaurs, relies heavily on the fossil-rich continental deposits of South America, their …

Triassic beds from Argentina and Brazil provide the most relevant fossil record of early
dinosauriforms in terms of numerical abundance and taxonomic diversity. This record …

Dinosaurs have been major components of ecosystems for over 200 million years. Although
different macroevolutionary scenarios exist to explain the Triassic origin and subsequent …

Dinosaurs diversified in two steps during the Triassic. They originated about 245 Ma, during
the recovery from the Permian-Triassic mass extinction, and then remained insignificant until …
