The stem-archosaur evolutionary radiation in South America
(2021-01-01)
The oldest archosauromorphs (dinosaurs, birds, crocodiles, and their stem-taxa) are recorded in middle−upper Permian rocks, but it was not after the Permo−Triassic mass extinction that the group shows a substantially high ...
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 ...
The rise of the ruling reptiles and ecosystem recovery from the Permo-Triassic mass extinction
(The Royal Society, 2018-06)
One of the key faunal transitions in Earth history occurred after the Permo-Triassic mass extinction (ca 252.2 Ma), when the previously obscure archosauromorphs (which include crocodylians, dinosaurs and birds) become the ...
Comparative bone microstructure of three archosauromorphs from the Carnian, late triassic chañares formation of Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2020-06)
The Chañares Formation exhibits one of the most important archosauriform records of early Carnian ecosystems. Here we present new data on the palaeohistology of Chañares archosauriforms and provide new insights into their ...
A new horned and long-necked herbivorous stem-archosaur from the Middle Triassic of India
(Nature Publishing Group, 2017-12)
The early evolution of archosauromorphs (bird- A nd crocodile-line archosaurs and stem-archosaurs) represents an important case of adaptive radiation that occurred in the aftermath of the Permo-Triassic mass extinction. ...
The Early Evolution of Rhynchosaurs
(Frontiers Media Sa, 2016-01-01)
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 ...
Unappreciated diversification of stem archosaurs during the Middle Triassic predated the dominance of dinosaurs
(BioMed Central, 2016-09)
Background: Archosauromorpha originated in the middle–late Permian, radiated during the Triassic, and gave rise to the crown group Archosauria, a highly successful clade of reptiles in terrestrial ecosystems over the last ...
Novos espécimes de Arcossauromorfos (Sauria: archosauromorpha) do Triássico inferior da América do Sul e suas implicações filogenéticas
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2019-02-28)
Archosauromorpha is defined as the clade that comprises all diapsids more closely related to the lineage of birds (Ornithodira) and crocodilians (Pseudosuchia) than with lepidosaurs. The main objective of this dissertation ...
First direct archosauromorph remains from the early-middle triassic transition of the Iberian Peninsula
(Coquina Press, 2018-01)
This paper discusses the taxonomic affinities of three isolated teeth discovered in the Buntsandstein facies of the Catalan Coastal Ranges and central-eastern Pyrenean basins that crop out in Catalonia, north-eastern Spain. ...
