The Late Triassic Ischigualasto Formation at Cerro Las Lajas (La Rioja, Argentina): fossil tetrapods, high-resolution chronostratigraphy, and faunal correlations
(Nature Publishing Group, 2020-07-29)
Present knowledge of Late Triassic tetrapod evolution, including the rise of dinosaurs, relies heavily on the fossil-rich continental deposits of South America, their precise depositional histories and correlations. We ...
New information on the braincase and endocranial morphology of the Late Triassic neotheropod Zupaysaurus rougieri using Computed Tomography data
(Society of Vertebrate Paleontology, 2019-05)
Zupaysaurus rougieri is an early neotheropod from the middle Norian Los Colorados Formation of northwestern Argentina represented by an almost complete skull and several postcranial bones. Most of its braincase morphology ...
Skull osteology of aetosauroides scagliai casamiquela, 1960 (archosauria: Aetosauria) from the late triassic of Brazil: New insights into the paleobiology of aetosaurs
(Coquina Press, 2021-11)
Aetosauroides scagliai, from the Ischigualasto Formation of Argentina and Santa Maria Supersequence of Brazil (Carnian-Norian), is one of the oldest members of Aetosauria, a diverse clade of armored crocodile-line archosaurs. ...
Late triassic hexactinellid sponges from the Pongo de Lorocache limestones, Peru: New evidence for siliceous sponge dominance on shallow carbonate platforms
(Asociación Paleontológica ArgentinaAR, 2018-04)
We hereby report the finding of Upper Triassic hexactinellid sponges in Pongo de Lorocache limestones, in the south edge of the Santiago basin, Peru (Fig. 1). The sponges were found in the uppermost levels of the Chambará ...
Ceratodus tunuensis, sp. nov., a new lungfish (Sarcopterygii, Dipnoi) from the Upper Triassic of central East Greenland
(Society of Vertebrate Paleontology, 2018-03)
The fossil record of post-Paleozoic lungfishes in Greenland is currently restricted to a few brief reports of isolated and undetermined tooth plates coming from the uppermost Fleming Fjord Formation (late Norian) in Jameson ...
Associated skeletons of a new middle Triassic ""Rauisuchia"" from Brazil
(SPRINGER, 2011)
For more than 30 million years, in early Mesozoic Pangea, ""rauisuchian"" archosaurs were the apex predators in most terrestrial ecosystems, but their biology and evolutionary history remain poorly understood. We describe ...
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 ...
Supradapedon revisited: geological explorations in the Triassic of southern Tanzania
(Peerj Inc, 2017-11-13)
The upper Triassic deposits of the Selous Basin in south Tanzania have not been prospected for fossil tetrapods since the middle of last century, when Gordon M. Stockley collected two rhynchosaur bone fragments from the ...
Triassic faunal successions of the Paraná Basin, southern Brazil
(Pergamon-Elsevier Science Ltd, 2020-12)
The Paraná Basin was filled by a sedimentary package deposited in successive sedimentation episodes related to the tectonic events that hit the SW portion of the Gondwana. The Triassic portion of this package, known worldwide ...
