Sedimentological and provenance response to Cambrian closure of the Clymene ocean: the upper Alto Paraguai Group, Paraguay belt, Brazil

, 2012
Final Gondwana amalgamation was marked by the closure of the Neoproterozoic Clymene ocean between the Amazonia craton and central Gondwana. The events which occurred in the last stage of this closure were recorded in the upper Alto Paraguai Group in the ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

The Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Late Permian-Triassic metallogeny in the Chinese Altay Orogen: Constraints from mica Ar-40/Ar-39 dating on ore deposits

, 2017
The Central Asian Orogenic Belt (CAOB) constitutes the largest Phanerozoic accretionary orogen on Earth. It extends over 5000 km and hosting numerous metal deposits. The Chinese Altay Orogen, an important element of the CAOB, hosts abundant Devonian (ca.

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

The Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.
