The Early Evolution of Rhynchosaurs
(Frontiers, 2016-01)
The rhynchosaurian archosauromorphs are an important and diverse group of fossil tetrapods that first appeared during the Early Triassic and probably became extinct during the early Late Triassic (early Norian). Here, the ...
Revision of the early crocodylomorph Trialestes romeri (Archosauria, Suchia) from the lower Upper Triassic Ischigualasto Formation of Argentina: one of the oldest-known crocodylomorphs
(Wiley-Blackwell Publishing Ltd, 2016-11-03)
Trialestes romeri (Reig) is an early crocodylomorph from the Ischigualasto Formation (late Carnian – early Norian; Ischigualasto – Villa Unión Basin, Argentina) and one of the oldest-known members of this clade. Two specimens ...
New material of Luperosuchus fractus (Archosauria: Crurotarsi) from the Middle Triassic of Argentina: the earliest known South American "Rauisuchian"
(Society of Vertebrate Paleontology, 2009-12)
"Rauisuchian" archosaurs were some of the largest terrestrial carnivores during the Middle and Late Triassic in Europe, North Africa, Asia, India, and the Americas (Gower, 2000). Despite their worldwide distribution, ...

Las contribuciones realizadas por Pablo Groeber al estudio del Triásico en la Argentina y, en especial, el capítulo dedicado al Sistema en Geografía de la República Argentina, que escribiera junto a Pedro Stipanicic, son ...
Detrital and volcanic zircon U–Pb ages from southern Mendoza (Argentina): An insight on the source regions in the northern part of the Neuquén Basin
(Elsevier, 2015-10)
The infill of the Neuquén Basin recorded the Meso-Cenozoic geological and tectonic evolution of the southern Central Andes being an excellent site to investigate how the pattern of detrital zircon ages varies trough time. ...
Primer registro de displasia coxofemoral en un rincosaurio del Triásico superiorFirst record of coxofemoral dysplasia in a late Triassic rynchosaur
(Asociación Paleontológica Argentina, 2013-05)
La paleopatología es la disciplina que se ocupa de enfermedades evidenciadas en el registro fósil. Este campo abarca la identificación de la patología y las consecuencias que la misma pudo dejar en el animal. En este aporte ...
Descrição, taxonomia, filogenia e evolução craniana de novos probainognátios não-mamaliaformes (Cynodontia: eucynodontia) sul-brasileiros
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2022-09-12)
Cynodontia comprises a large synapsid clade that includes numerous species, both nonMammaliaformes and Mammaliaformes. Non-mammaliaform forms were among the most
conspicuous components of the continental paleofauna of ...
Geochronology and geochemistry of zircon for plutonic complexes of the Coastal Cordillera in Northern Chile
(Universidad de Chile, 2021)
The Coastal Cordillera represents the first stage of the Andean orogeny that started nearly 200 Ma ago with subduction reactivation after an anorogenic period. However, recent studies have questioned the tectonic regime ...
A high-precision U–Pb zircon age constraints the timing of the faunistic and palynofloristic events of the Carnian Ischigualasto Formation, San Juan, Argentina
(Pergamon-Elsevier Science Ltd, 2021-11)
The Late Triassic represents records many of the most critical biotic crises in life-history (from Carnian to the end-Triassic extinction, ETE). Some hypotheses propose that these life changes were linked with shifts in ...
