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 ...
Age constraints on the dispersal of dinosaurs in the Late Triassic from magnetochronology of the Los Colorados Formation (Argentina)
(National Academy of Sciences, 2014-04)
A measured magnetozone sequence defined by 24 sampling sites with normal polarity and 28 sites with reverse polarity characteristic magnetizations was established for the heretofore poorly age-constrained Los Colorados ...
A new rhynchosaur maxillary tooth plate morphotype expands the disparity of the group in the Ischigualasto Formation (Late Triassic) of Northwestern Argentina
(Taylor & Francis Ltd, 2018-02)
Rhynchosaurs are a clade of quadruped, herbivorous stem-archosaur diapsids restricted to the Triassic Period. The group became globally distributed and the numerically dominant tetrapods of several terrestrial ecosystems ...
New specimen sheds light on the anatomy and taxonomy of the Early Late Triassic Dinosauriforms from the Chañares Formation, NW Argentina
(Veterinary and Human Toxicology, 2020-05)
The lower Carnian levels of the Chañares Formation (IschigualastoVilla Unión Basin, La Rioja Province) have yielded some of the most informative dinosaur precursor species known so far. However, these species are based on ...
Allogenic controls on the fluvial architecture and fossil preservation of the Upper Triassic Ischigualasto Formation, NW Argentina
(Elsevier Science, 2017-12)
The Upper Triassic Ischigualasto Formation in NW Argentina was deposited in a fluvial system during the synrift filling of the extensional Ischigualasto-Villa Unión Basin. The expansive exposures of the fluvial architecture ...
Tetrapod burrows from the Middle–Upper Triassic Chañares Formation (La Rioja, Argentina) and its palaeoecological implications
(Elsevier Science, 2018-05)
We describe tetrapod burrows from the uppermost Middle–lower Upper Triassic (latest Ladinian–early Carnian) Chañares Formation (Ischigualasto-Villa Unión Basin), La Rioja Province, northwestern Argentina. The burrows were ...
Palaeobotany and palynology of coprolites from the Late Triassic Chañares Formation of Argentina: implications for vegetation provinces and the diet of dicynodonts
(Elsevier Science, 2018-08)
The early Late Triassic Chañares Formation of Argentina contains one of the richest tetrapod-bearing assemblages of this age worldwide and is important for understanding the origin and early radiation of suchians, ...
Paleoenvironmental and Biotic Changes in the Late Triassic of Argentina: Testing Hypotheses of Abiotic Forcing at the Basin Scale
(Frontiers Media, 2022-06)
Paleoenvironmental factors such as climate change are often hypothesized as critical for ecosystem changes over evolutionary time scales. Theoretically, these changes should be observable in the fossil record, but the ...
Paleobotany of the Upper Triassic Los Rastros Formation, Ischigualasto–Villa Unión Basin, La Rioja, Argentina
(Pergamon-Elsevier Science Ltd, 2020-10)
The Los Rastros Formation was deposited in a deltaic-lacustrine environment during the Late Triassic. Plant remains from the Gualo area were systematically collected and compared with other localities from the Los Rastros ...
