Evolution of titanosaurid sauropods. I: phylogenetic analysis based on the postcranial evidence
"The phylogenetic relationships of titanosaurid sauropods are examined by means of a clodistic parsimony analysis based on postcranel features. Eusauropoda tBarapasaurus tagorei + Neosauropoda) have,Expand
A new giant carnivorous dinosaur from the Cretaceous of Patagonia
TLDR
A new giant carnivorous dinosaur from the Upper Creta-ceous of northwestern Patagonia (Argentina) is reported, characterized by a proportionally low skull, a reduced shoulder girdle, and robust vertebrae and hind limbs, and provides an opportunity to exam-ine the Gondwanan dinosaur palaeocommunities and their relation to those from Laurasia.

A new close relative of Carnotaurus sastrei Bonaparte 1985 (Theropoda: Abelisauridae) from the Late Cretaceous of Patagonia
Infoquest Foundation, 160 Cabrini Boulevard #48, New York, New York 10033, U.S.AINTRODUCTIONAbelisaur dinosaurs, theropods with unusual horned skullssuch as Majungatholus (Sampson et al., 1998) andExpand
Sauropod dinosaur embryos from the Late Cretaceous of Patagonia
TLDR
The first known unequivocal embryonic remains of sauropod dinosaurs—the only known non-avian dinosaur embryos from Gondwana—are described from a nesting ground in the Upper Cretaceous stage of Patagonia, Argentina and it is proposed that these specimens belong to the same sauroPod species. Expand
A basal iguanodontian (Ornithischia: Ornithopoda) from the Late Cretaceous of South America
ABSTRACT The ornithopod dinosaur Gasparinisaura cincosaltensis gen. et sp. nov. is described. This new taxon from the Upper Cretaceous of northwest Patagonia (Argentina) represents the first reportExpand
A new carcharodontosaurid (Dinosauria, Theropoda) from the Upper Cretaceous of Argentina
A new carcharodontosaurid theropod from the Huincul Formation (Aptian-Cenomanian, Upper Cretaceous) of Neuquen Province, Argentina, is described. Approximately the same size as GiganotosaurusExpand
Stratigraphy and Magnetostratigraphic/Faunal Constraints for the Age of Sauropod Embryo-Bearing Rocks in the Neuquén Group (Late Cretaceous, Neuquén Province, Argentina)
TLDR
The stratigraphy and age of a sauropod nesting ground containing the first definitive embryonic remains of sauropods preserved inside their eggs is analyzed and the Reverse polarity determinations for the fossiliferous sediments in the Anacleto Member argue for an age younger than the long Cretaceous C34 Normal, which ends at the upper boundary of the Sartonian and older than the late Campanian. Expand
THE BRAINCASE OF GIGANOTOSAURUS CAROLINII (DINOSAURIA: THEROPODA) FROM THE UPPER CRETACEOUS OF ARGENTINA
Abstract Giganotosaurus carolinii is one of the largest known theropod dinosaurs. Its remains include a well-preserved braincase that displays a suite of derived characters unique to the animal, andExpand
A NEW IGUANODONTIAN ORNITHOPOD FROM NEUQUEN BASIN, PATAGONIA, ARGENTINA
Abstract The discovery of a new iguanodontian ornithopod in the lower units of the Neuquen Group (Rio Limay Formation, early Upper Cretaceous) increases the South American record of this kind ofExpand
