Palynology of the Late Triassic Ischigualasto Formation, Argentina: Paleoecological and paleogeographic implications
(Elsevier Science, 2016-05)
In this study we describe and compare the palynological assemblages from the Carnian Ischigualasto Formation of westernmost Gondwana to those of eastern Gondwana, which have been referred to the Onslow and Ipswich ...
Evidence for the Carnian Pluvial Episode in Gondwana: New multiproxy climate records and their bearing on early dinosaur diversification
(Elsevier Science, 2020-10)
The Triassic hothouse world experienced dynamic changes in climate and ecosystems that set the Earth's climate and biotic states for much of the Mesozoic Era. A critical time interval was the Carnian Stage (~237–227 Ma), ...
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 ...
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 ...
The rhynchosaur record, including a new stenaulorhynchine taxon, from the Chañares Formation (upper Ladinian–?lowermost Carnian levels) of La Rioja Province, north-western Argentina
(Taylor & Francis, 2021-01-22)
Rhynchosaurs were quadrupedal, bulky herbivorous archosauromorph diapsids with a highly specialized dental apparatus. This group is restricted to the Triassic Period and became extremely abundant worldwide during the late ...
New hemipteran insects (Eoscarterellidae, Scytinopteridae, and Protopsyllidiidae) from the Upper Triassic Potrerillos Formation of Mendoza, Argentina
(Springer Heidelberg, 2016-02)
New species of Eoscarterellidae, Scytinopteridae, and Protopsyllidiidae are described from the Upper Triassic Potrerillos Formation, Cuyana Basin, MendozaProvince, Argentina. These specimens represent the first record of ...
Ecomorphology and bone microstructure of Proterochampsia from the Chañares Formation
(Polish Academy of Sciences. Institute of Paleobiology, 2019-05)
Proterochampsians are a South American endemic group of non-archosaurian archosauriforms with morphological characteristics recollecting Recent crocodilians, and therefore have been proposed as aquatic species. However, ...
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 ...
The genera Heidiphyllum and Dordrechtites, and associated fossil wood from the Triassic Ischichuca Formation, northwestern Argentina
(Pergamon-Elsevier Science Ltd, 2021-04)
New fossil plants are described from the Ischichuca Formation (Middle?–Late Triassic), La Rioja province, northwestern Argentina. A systematic description of Heidiphyllum leaves, ovulate structures of Dordrechtites and ...
