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. 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
Osteology and phylogenetic relationships of Tehuelchesaurus benitezii (Dinosauria, Sauropoda) from the Upper Jurassic of Patagonia
TLDR
The phylogenetic relationships of this taxon are tested through an extensive cladistic analysis that recovers Tehuelchesaurus as a non-titanosauriform camarasauromorph, deeply nested within Neosauropoda. Expand
The Osteology of Chubutisaurus insignis Del Corro, 1975 (Dinosauria: Neosauropoda) from the ‘Middle’ Cretaceous of Central Patagonia, Argentina
TLDR
The phylogenetic analysis presented here resolves Chubutisaurus as the most basal somphospondylian. Expand
A NEW SPECIMEN OF NEUQUENSAURUS AUSTRALIS, A LATE CRETACEOUS SALTASAURINE TITANOSAUR FROM NORTH PATAGONIA
Abstract A new specimen of the sauropod titanosaur Neuquensaurus australis, collected in the locality of Cinco Saltos (Patagonia, Argentina), provides an opportunity to improve our knowledge of theExpand
A new basal rebbachisaurid (Sauropoda, Diplodocoidea) from the Early Cretaceous of the Neuquén Basin; evolution and biogeography of the group
Despite that the origin of rebbachisaurids is retrieved as Late Jurassic is not until the upper Lower Cretaceous that this group can be recognised in the fossil record. The group is geographicallyExpand
EVOLUTION OF TITANOSAURID SAUROPODS. II: THE CRANIAL EVIDENCE
"The titanosaurid skull is interpreted as Camarasaurus-Iike, but with ""peg-like"" teeth restricted to the extremity of the jaws, which exhibit wear facets sharply inclined with respect to theExpand
Demandasaurus darwini, a New Rebbachisaurid Sauropod from the Early Cretaceous of the Iberian Peninsula
A new medium-sized rebbachisaurid sauropod from the Castrillo la Reina Formation (Upper Barremian-Lower Aptian) in Burgos Province, Demandasaurus darwini gen. et sp. nov., is described. It is knownExpand
A new giant titanosaur sheds light on body mass evolution among sauropod dinosaurs
TLDR
A new giant titanosaur is described, which represents the largest species described so far and one of the most complete titanosaurs, and its inclusion in an extended phylogenetic analysis and the optimization of body mass reveals the presence of an endemic clade of giant titanosaurs inhabited Patagonia between the Albian and the Santonian.
