The intermediate to acid Choiyoi Magmatic Province is the most conspicuous feature along
the Late Paleozic continental margin of southwestern Gondwana, and is generally regarded …

Fossil age data and molecular sequences are increasingly combined to establish a
timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically …

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 …

In this classic segment, many tectonic processes, like flat-subduction, terrane accretion and
steepening of the subduction, among others, provide a robust framework for their …

The opening of the South Atlantic in the Early Cretaceous was the final stage of the complex
rifting history of SW Gondwana. In this contribution we reassess the chronology of Mesozoic …

Triassic igneous and sedimentary rocks exposed within the basement of the Andes were
deposited in a series of rifts, and may record the early disassembly of western Pangaea …

The compilation of stratigraphic, sedimentologic, paleontologic and geochronological data
allows the proposal of a regional stratigraphic framework for the Late Permian to Lower …

Abstract The Puesto Viejo Group crops out in the San Rafael Block, southwest Mendoza, at
approximately 35° S and 68° 20′ W. It consists of the basal mainly grayish Quebrada de los …

The Triassic hothouse world experienced dynamic changes in climate and ecosystems that
set the Earth's climate and biotic states for much of the Mesozoic Era. A critical time interval …

Abstract The Triassic Period was the setting for the origin and early diversification of
Mesozoic ecosystems after the end-Permian mass extinction. The study of the Triassic is …
