Evolution of titanosaurid sauropods. I: phylogenetic analysis based on the postcranial evidence
Titanosaurids more derived than Epachthosaurus sciuttoi Powell and Malawisaurus dixeyi Haughton have medial prespinal lamina formed down to the base of neural spine in posterior trunk vertebrae and quadrangular coracoids.
A new giant carnivorous dinosaur from the Cretaceous of Patagonia
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 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 report…
Osteology and phylogenetic relationships of Tehuelchesaurus benitezii (Dinosauria, Sauropoda) from the Upper Jurassic of Patagonia
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.
The Osteology of Chubutisaurus insignis Del Corro, 1975 (Dinosauria: Neosauropoda) from the ‘Middle’ Cretaceous of Central Patagonia, Argentina
The phylogenetic analysis presented here resolves Chubutisaurus as the most basal somphospondylian.
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 the…

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.

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 known…
UBERABATITAN RIBEIROI, A NEW TITANOSAUR FROM THE MARÍLIA FORMATION (BAURU GROUP, UPPER CRETACEOUS), MINAS GERAIS, BRAZIL
Abstract: A new Late Cretaceous titanosaur sauropod from the Bauru Basin of Brazil, Uberabatitan ribeiroi gen. et sp. nov., represented by at least three specimens, is described. The material comes…
