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 SPECIES OF ARARIPESUCHUS (CROCODYLOMORPHA, MESOEUCROCODYLIA) FROM THE LOWER CRETACEOUS OF PATAGONIA (ARGENTINA)
TLDR
Araripesuchus is proposed here as being the sister taxon of Neosuchia, corroborating previous phylogenetic analysis and allowing a reanalysis of the role played by their amphiatlantic distribution in the Aptian-Albian. Expand
A new Cretaceous terrestrial ecosystem from Gondwana with the description of a new sauropod dinosaur.
TLDR
A unique site at the northern area of Patagonia reveals a terrestrial ecosystem preserved in a detail never reported before in a Late Cretaceous deposit, including a new titanosaur sauropod, Futalognkosaurus dukei n.gen. Expand
A NEW TITANOSAUR SAUROPOD FROM THE LATE CRETACEOUS OF NEUQUÉN, PATAGONIA, ARGENTINA 1
TLDR
A cladistic phylogenetic analysis placed Muyelensaurus pecheni gen. et sp.nov. Expand
A bizarre Cretaceous theropod dinosaur from Patagonia and the evolution of Gondwanan dromaeosaurids
TLDR
The new discovery amplifies the range of morphological disparity among unenlagiines, demonstrating that by the end of the Cretaceous this clade included large, short-armed forms alongside crow-sized, long-armed, possibly flying representatives. Expand
Neuquenornis volans, a new Late Cretaceous bird (Enantiornithes: Avisauridae) from Patagonia, Argentina
ABSTRACT A new genus and species of Late Cretaceous (Coniancian–Santonian) birds, Neuquenornis volans, is described. This new taxon is known from a fairly complete, articulated specimen from the RioExpand
Andesaurus delgadoi gen et sp. nov. (Saurischia-Sauropoda), dinosaurio Titanosauridae de la formacion Río Limay (Albiano-Cenomaniano), Neuquen, Argentina
A good part of the postcranial skeleton of an Albian-Cenomanian primitive titanosaurid from Patagonia is described and discussed. The posterior dorsal vertebrae are high, with slight opisthocoeliousExpand
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
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
Phylogenetic status of Megaraptor namunhuaiquii Novas based on a new specimen from Neuquén, Patagonia, Argentina
TLDR
A new specimen of Megaraptornamunhuaiquii was discovered on the north coast of the Barreales lake, Neuquen, Argentina and offers more information to elucidate its phylogenetic relationships. Expand
