Dinosaur remains from the Lower Cretaceous of the Chubut Group, Argentina

Cretaceous Research, 2003
Abstract Some fragmentary dinosaur remains from the uppermost Hauterivian–Barremian La Paloma Member of the Cerro Barcino Formation of northern Chubut, Argentina are described. Together with the fauna from the La Amarga Formation of Neuquen, Argentina, this material represent the oldest known Cretaceous dinosaur fauna from South America.

A new lizard species of the Liolaemus kingii group (Squamata: Liolaemidae) from northwestern Chubut province (Argentina)

Zootaxa, 2023
We describe Liolaemus attenboroughi sp. nov., a lizard distributed in the northwestern Patagonian Steppe of Chubut province (Argentina) previously confused with L. kingii (Bell 1843). Recent studies based on molecular evidence supports its evolutionary independence.

New materials and an overview of Cretaceous vertebrates from the Chubut Group of the Golfo San Jorge Basin, central Patagonia, Argentina

Journal of South American Earth Sciences, 2020
Abstract In this paper, we present an updated revision of fossil vertebrates from the Chubut Group, Golfo San Jorge Basin, while also describing some new remains. Extensive exposures of both Lower and Upper Cretaceous sedimentary sequences are present in central Patagonia.

Growth pattern of the Tehuelche and Mapuche ethnic population groups of the rural districts of Chubut, South Patagonia, Argentina

International Journal of Anthropology, 2002
This investigation is aimed at recording the conditions of life and of reproduction of the population of the rural districts of the Province of Chubut, in South Patagonia. These districts, where in 1991 more than 50% of the population lived in towns of less than 2000 inhabitants, have an important indigenous component of the Tehuelche and Mapuche ...

Geometry, Lithofacies, and Spatial Distribution of Cretaceous Fluvial Sandstone Bodies, San Jorge Basin, Argentina: Outcrop Analog for the Hydrocarbon-Bearing Chubut Group

SEPM Journal of Sedimentary Research, 2000
Abstract Fluvial deposits of the Cretaceous Chubut Group, San Jorge Basin, Argentina, were studied in outcrop to provide analogs for adjacent subsurface hydrocarbon-bearing strata. Outcrops were described using photomosaics and detailed sedimentological logs.

Patterns and origins of the porosity in the productive reservoirs of the upper part of the Chubut Group, southern flank of the Golfo de San Jorge Basin, Patagonia Argentina

Journal of South American Earth Sciences, 2020
Abstract The Mina del Carmen, Bajo Barreal and Canadon Seco Formations bear the most important Cretaceous reservoirs in the southern flank of the Golfo de San Jorge Basin, in which the porosity is mainly secondary in origin. Primary porosity is about 4% in average and can be divided in intergranular and intercrystalline porosity, the former is better

Comparative structural analysis of inverted structures in the San Bernardo fold belt (Golfo San Jorge basin, Argentina): Inversion controls and tecto-sedimentary context of the Chubut Group

Journal of South American Earth Sciences, 2020
Abstract The Golfo San Jorge Basin is one of the most important hydrocarbon-bearing basins of Argentina. Its position in the distal Patagonian Broken Foreland confers a particular structural architecture. Specifically, the western margin was affected by positive tectonic inversion, with higher degrees of inversion at the San Bernardo Fold Belt (SBFB).

The Chubut Group at the San Bernardo fold belt, Golfo San Jorge basin, Argentina: A review of fossil plant localities and its sedimentological setting

Journal of South American Earth Sciences, 2019
Abstract The Chubut Group (Cretaceous) consists of continental volcaniclastic deposits widely distributed in the Golfo San Jorge and Canadon Asfalto basins of Central Patagonia. In the San Bernardo Fold Belt, numerous outcrops with fossil plants have been historically mentioned.
