Postcranial morphology of the Early Triassic epicynodont Galesaurus planiceps (Owen) from the Karoo Basin, South Africa
(Wiley, 2018-06)
The Early Triassic non-mammaliaform epicynodont Galesaurus planiceps formed an important part of ecosystems following the Permo-Triassic Mass Extinction, the greatest mass extinction in Phanerozoic history. Here, we ...
Mudanças hidroclimáticas e no padrão de oxigenação de água de fundo ao longo do limite Triássico-Jurássico na seção Levanto-Maino, Peru: possíveis gatilhos vulcânicos
(Universidade do Vale do Rio dos Sinos, 2022-03-03)
The evolution of the Earth is marked by different periods of mass extinction, the main five being called the Big Five. Often these extinctions are associated with Large Igneous provinces (LIPs). The Triassic-Jurassic ...

The Brachiopod Dalmanella testudinaria across the End Ordovician Extinction Event in the Cuyania Terrane of Western Argentina
(Asociación Paleontológica Argentina, 2019-10)
The species Dalmanella testudinaria (Dalman) was reported thirty years ago from the Hirnantian Don Braulio Formation of the Argentinean Precordillera, but its assignment was cast in doubt by a recent revision of the species. ...
Paleoecotoxicology: the impact of chemical and physical stress in the evolutionary process
(U.S. Department of Health and Human Sciences. Public Health and Science, 2001-05)
Present-day biodiversity, estimated to comprise more than 100 millionspecies, has developed in around 4,000 million years on the basisof the ability of life forms to adapt and multiply at a rate that surpassedextinctions. ...
Discovery of four new massive and dense cold cores
(UNIV CHICAGO PRESS, 2004-07-20)
We report the identification, from a 1.2 mm dust continuum emission survey toward massive star-forming regions, of four strong 1.2 mm sources without counterparts at mid-infrared (Midcourse Space Experiment [MSX]) and ...
Can social and sexual selection explain the bizarre snout of proterosuchid archosauriforms?
(Taylor & Francis, 2016-03)
Proterosuchids are a clade of quadrupedal, carnivorous Permo-Triassic diapsids crucial to understand the successful evolutionary radiation of archosaurs during the Mesozoic. The importance and good fossil record of ...
