Analysis of a Permo-Triassic polarity transition in different absolute reconstructions of Pngaea, considering a model with features of the Present Earth Magnetic Field
(Istituto Nazionale di Geofisica e Vulcanologia, 2007-12)
The main objective of this paper is to show that the distribution of transitional palaeomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a model that considers ...
Mass extinctions drove increased global faunal cosmopolitanism on the supercontinent Pangaea
(Nature Publishing Group, 2017-12)
Mass extinctions have profoundly impacted the evolution of life through not only reducing taxonomic diversity but also reshaping ecosystems and biogeographic patterns. In particular, they are considered to have driven ...
A basal dinosaur from the dawn of the dinosaur era in southwestern pangaea
(American Association for the Advancement of Science, 2011-01)
Upper Triassic rocks in northwestern Argentina preserve the most complete record of dinosaurs before their rise to dominance in the Early Jurassic. Here, we describe a previously unidentified basal theropod, reassess its ...
Palaeomagnetic results from the Early Permian Copacabana Group, southern Peru: Implication for Pangaea palaeogeography
(ElsevierNL, 2006)
Muestras recolectadas de rocas carbonatadas, plegadas del Grupo Copacabana Pérmico, expuestas en la zona subandina peruana han sido sometidas al análisis paleomagnético detallado. Las direcciones generales de pasar la ...
Was Mesosaurus a Fully Aquatic Reptile?
(Frontiers Research Foundation, 2018-07-27)
Mesosaurs have been considered strictly aquatic animals. Their adaptations to theaquatic environment are well known and include putative viviparity, along with thepresence of several skeletal characters such as a long, ...
Phylogenetic reappraisal of Rhytidosteidae (Stereospondyli: Trematosauria), temnospondyl amphibians from the Permian and Triassic
(Taylor & Francis, 2011-06)
All stereospondyl taxa previously placed within Rhytidosteidae are reviewed in a phylogenetic context. A parsimony analysis shows that Pneumatostega, Trucheosaurus, Rhytidosteus and Nanolania are placed outside Rhytidosteidae. ...
Jurassic-Early Cretaceous intermediate virtual geomagnetic poles and Pangaean subduction zones
(Elsevier Science, 2008-02)
The objective of this paper is to show that the distribution of Jurassic-Early Cretaceous intermediate virtual geomagnetic poles (VGPs) seems to be conditioned by Pangaean subducted slabs. Palaeomagnetic data from between ...
Evolução da margem atlântica equatorial do Brasil: Três fases distensivas
(2008-12-01)
The extension of the Pangaea started in the Upper Triassic and evolved to uplifts, magmatism and development a triple junction during the Mesozoic, and opening the Central Atlantic Ocean. The Brazilian Equatorial Atlantic ...
