Biotic recovery after the end-Triassic extinction event: Evidence from marine bivalves of the Neuquén Basin, Argentina
(Elsevier Science, 2017-12)
We analyze the Late Triassic extinction and Early Jurassic recovery of bivalve faunas within marine environments in the Atuel River area of the Neuquén Basin, Argentina. Data were collected from a hundred samples with ...
A late norian-rhaetian coelophysid neotheropod (dinosauria, saurischia) from the quebrada del barro formation, Northwestern Argentina
(Asociacion Paleontologica Argentina, 2017-11)
Coelophysoids are the most abundant theropod dinosaurs known from the Late Triassic through Early Jurassic and represent the earliest major radiation of Neotheropoda. Within Coelophysoidea sensu lato, the most stable clade ...
A new Late Triassic dipteridacean fern from the Paso Flores Formation, Neuquén Basin, Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2021-11)
Sterile and fertile fronds of dipteridacean ferns from the Paso Flores Formation (late Norian–Rhaetian) at Cañadón de Pancho area, south of the Neuquén Province, Patagonia (Neuquén Basin), Argentina, are described. The ...
Spatial coincidence and similar geochemistry of Late Triassic and Eocene-Oligocene magmatism in the Andes of northern Chile: evidence from the MMH porphyry type Cu-Mo deposit, Chuquicamata district
(Springer, 2018)
The MMH porphyry type copper-molybdenum deposit in northern Chile is the newest mine in the Chuquicamata District, one of largest copper concentrations on Earth. Mineralized Eocene-Oligocene porphyry intrusions are hosted ...
Siliceous sponges from the Upper Triassic-Lower Jurassic, Pucará Group, Peru: new evidence of a faunal recovery during the extinction event
(Asociación Paleontológica ArgentinaAR, 2016-10)
Across the Triassic-Jurassic transition, an important change in atmospheric pCO2 was recorded, concomitant with the eruption and emplacement of the Central Atlantic Magmatic Province and the splitting of Pangea. Upper ...
Basal Sauropodomorpha (Dinosauria, Saurischia) of Gondwana
(Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" e Instituto Nacional de Investigación de las Ciencias Naturales, 2016-05)
Sauropodomorfos basales de Argentina. Los sauropodomorfos basales incluyen a los sauropodomorfos no saurópods, que habitaron todos los continentes entre el Triásico Superior y el Jurásico Inferior. La evolución temprana ...
Middle Triassic dipterid ferns from west-central Argentina and their relationship to palaeoclimatic changes
(Polish Academy of Sciences. Institute of Paleobiology, 2018-06)
Dipterid ferns possess robust fossil record from Mesozoic times on, and they are considered to be a reliable indicator of warm to subtropical humid or seasonal paleoclimatic conditions. In this contribution, we revised and ...
