The Neuquén Basin in northwestern Patagonia, Argentina, holds the most important record of Cretaceous dinosaurs in South America.The Neuquén Group (Upper Cretaceous) is the richest dinosaur-bearing unit of the basin. It comprises the Río Limay, the Río Ne... see more

The present work describes a new species of Baurusuchidae from Upper Cretaceous sediments of the Bauru Basin, and provides the first complete postcranial description for the family. Many postcranial features observed in the new species are also present in... see more

The uppermost Cretaceous continental deposits of the Neuquén Basin (west-central Argentina) have yielded a high diversity vertebrate assemblage, including numerous dinosaur species. The Neuquén Group is the richest unit in remains of dinosaur of the basin... see more

The mid-Cretaceous succession of the central Southern Alps (Trento and Verona) is mainly represented by basinal deposits of the Scaglia Variegata.In this paper, the presence of a Radiolitidae in the Scaglia Variegata of the Lessini Mountains is reported. ... see more

Upper Cretaceous intrusives of limited extent crop out in the Coastal Cordillera near of Valdivia (39º48’ S), 100 km west of the main topographic divide of the Andean Cordillera. Given that plutonic rocks of the same age crop out at the same latitudes in ... see more

This study documents the main depositional elements of a dynamically-controlled sand-rich deep-water turbidite system (Upper Cretaceous–Palaeocene Gottero system, north-west Italy). The large exposures and the wide range of facies and deep-water sub-envir... see more

The branched trace fossil Chondrites affinis (Sternberg, 1833), synonymised so far with C. targionii (Brongniart, 1828), has been analyzed in an exceptionally well preserved specimen from the Saraceno Formation (?Upper Cretaceous; ?Eocene-Miocene) in the ... see more

Cretaceous porphyry copper deposits of northern Chile (28º-29º30’ S) are genetically related with dacitic to dioritic porphyries and they represent a still poorly-explored target for Cu resources. The porphyries correspond to stocks distributed into two s... see more

New sedimentological and fossil-diagenetic information from remains of four dinosaurs is herein provided. The fossil material was preserved in deposits of different fluvial sub-environments from the middle section of the Lago Colhué Huapi Formation, Golfo... see more
