Late Triassic environmental evolution in Southwestern Pangea: Plan taphonomy of the Ischigualasto Formation
(Society for Sedimentary Geology, 2008-12-01)
The Ischigualasto Formation was deposited in a fluvial system and contains a very well preserved Triassic flora. This flora comprises seven taphofacies: (1) C(St), autochthonous silicified roots of lowstatured, woody plants ...
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 ...
Vertebrate Succession in the Ischigualasto Formation
(Society Of Vertebrate Paleontology, 2013-09)
The Upper Triassic (Carnian-Norian) Ischigualasto Formation has yielded a diverse vertebrate fauna that records the initial phase of the evolution of dinosaurs. Radioisotopic dates from ash layers within the formation ...
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 ...
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 ...
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 ...
Diagénesis y procedencia de la formación Los Colorados (Noriano), cuenca de Ischigualasto – Villa Unión, noroeste de ArgentinaDiagenesis and provenance of the Los Colorados Formation (Norian), Ischigualasto Villa Unión Basin, northwest of Argentina
(Asociación Geologica Argentina, 2015-03)
En este trabajo se discuten la historia diagenética y las áreas de proveniencia de la Formación Los Colorados, unidad de bancos rojos que representa el relleno final de la cuenca triásica de Ischigualasto-Villa Unión. Esta ...
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 ...
Registro de la Relación Isotópica de Carbono en la paleoflora de la Formación Ischigualasto (Triásico Superior), Noroeste Argentina: Implicancias paleoatmosféricasFloral Carbon Isotopic Record, Ischigualasto Formation (Upper Triassic), Northwest Of Argentina: Paleoatmospheric Implications
(Sociedade Brasileira de Paleontologia, 2011-04)
La Formación Ischigualasto, del Triásico superior, es portadora de una paleoflora muy bien preservada en su porción media-superior (~225Ma). En esta contribución se detallan los primeros estudios isotópicos (i.e. carbono ...
