Synopsis Titanosaurs represent approximately one‐third of sauropod diversity and were geographically widespread throughout the Cretaceous, especially on southern continents. [...] Key Method A re‐evaluation of all Titanosaurus species recognises as diagnostic only f...Expand
An Overview of Titanosaur Evolution and Phylogeny Una revisión de la evolución y fi logenia de los Titanosaurios
TLDR
Evaluation of previous phylogenetic analyses of Titanosauria provides insight into the structure of the character data thus far generated and a starting point for future studies, as well as identifying several stable titanosaur nodes and a core of character data for future analysis. Expand
New information on the Cretaceous sauropod dinosaurs of Zhejiang Province, China: impact on Laurasian titanosauriform phylogeny and biogeography
TLDR
A detailed re-description and diagnosis of Jiangshanosaurus is provided, as well as new anatomical information on Dongyangosaurus, to provide further support for a widespread diversification of titanosaurs by at least the Early Cretaceous. Expand
The Titanosaur (Dinosauria: Sauropoda) Osteoderm Record: Review and First Definitive Specimen from India
TLDR
A titanosaur osteoderm from the Maastrichtian of India is described that extends the geographic range of these armored sauropods and appears that armored titanosaurs are relatively diminutive in body size. Expand
The early evolution of titanosauriform sauropod dinosaurs
TLDR
A re-evaluation of the phylogenetic affinities of fragmentary taxa based on these synapomorphies found no body fossil evidence for titanosaurs before the middle Cretaceous (Aptian), in contrast to previous reports of Middle and Late Jurassic forms. Expand
The earliest known titanosauriform sauropod dinosaur and the evolution of Brachiosauridae
TLDR
Vouivria is a basal brachiosaurid, confirming its status as the stratigraphically oldest known titanosauriform, and implementation of sensitivity analyses, in which these characters are excluded, has no effect on tree topology or resolution. Expand
A reassessment of Mongolosaurus haplodon Gilmore, 1933, a titanosaurian sauropod dinosaur from the Early Cretaceous of Inner Mongolia, People's Republic of China
TLDR
Assessment of Mongolosaurus provides new information on the atlas-axis complex, and highlights several new characters that may prove useful in future phylogenetic analyses, such as the ratio of the transverse widths of the basal tubera and occipital condyle. Expand
The Chinese colossus: an evaluation of the phylogeny of Ruyangosaurus giganteus and its implications for titanosaur evolution
TLDR
Ruyangosaurus is here recovered as a lognkosaurian, with significant implications for the distribution and evolution of that group and the paleobiology of Mid-Cretaceous China. Expand
Anatomy of the basal titanosaur (Dinosauria, Sauropoda) Andesaurus delgadoi from the mid-Cretaceous (Albian–early Cenomanian) Río Limay Formation, Neuquén Province, Argentina: implications for titanosaur systematics
TLDR
The holotype of Andesaurus delgadoi is re-describe, comprising dorsal, sacral, and caudal vertebrae, as well as limb and pelvic elements, and putative titanosaur synapomorphies are recognized. Expand
ON A TITANOSAURID (DINOSAURIA, SAUROPODA) VERTEBRAL COLUMN FROM THE BAURU GROUP, LATE CRETACEOUS OF BRAZIL
1 ABSTRACT: A new titanosaurid dinosaur from the Late Cretaceous continental deposits of the Bauru Group is described. Trigonosaurus pricei n.gen., n.sp., is based on two specimens, both collected atExpand
A Reappraisal of the Late Cretaceous Argentinean Sauropod Dinosaur Argyrosaurus superbus, with a Description of a New Titanosaur Genus
TLDR
Argyrosaurus is redescribe, demonstrating it to be a valid titanosaur genus based on five autapomorphies, as well as an unique character combination, which provides new information on this diverse but still poorly understood clade. Expand

The last of the dinosaur titans: a new sauropod from Madagascar
TLDR
A total-evidence phylogenetic analysis supports a close relationship between brachiosaurids and titanosaurs (Titanosauriformes), and the inclusion of cranial data from Rapetosaurus lays to rest questions concerning the phylogeny of the enigmatic Mongolian genera Nemegtosaurus and Quaesitosaurus. Expand
New titanosaurid (Dinosauria: Sauropoda) from the Late Cretaceous of central India
TLDR
New titanosaurid skeletal material described here represents part of an individual in associated and mostly articulated condition, though skull, hind limb and foot bones are missing, making the present find valuable in understanding these specialized sauropods. Expand
Sauropod dinosaurs from the Lower Cretaceous of eastern Asia: taxonomic and biogeographical implications
Sauropod dinosaurs are poorly represented in the Lower Cretaceous of eastern Asia. Here, we describe a number of isolated sauropod teeth from the Kuwajima Formation (?Berriasian–?Hauterivian) ofExpand
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
The phylogenetic relationships of sauropod dinosaurs
TLDR
The results suggest that there are dangers inherent in the view that ‘higher’ level sauropod phylogeny can be accurately reconstructed using only a small number of well-known taxa, and that the results of the randomization tests indicate that the data-matrix probably contains a strong phylogenetic ‘signal’. Expand
THE ANATOMY AND TAXONOMY OF CETIOSAURUS (SAURISCHIA, SAUROPODA) FROM THE MIDDLE JURASSIC OF ENGLAND
TLDR
It is proposed that the generic name Cetiosaurus be retained, with C. oxoniensis as the new type species, because the two forms do not share any autapomorphies. Expand
Sauropod dinosaur phylogeny: critique and cladistic analysis
TLDR
A lower-level phylogenetic analysis of Sauropoda is presented, which resolves six sauropod outgroups to Neosauropoda, which comprises the large-nostrilled clade Macronaria and the peg-toothedclade Diplodocoidea. Expand
The phylogenetic relationships of the Nemegtosauridae (Saurischia, Sauropoda)
TLDR
Cladistic analysis supports the hypothesis that nemegtosaurid are the sister-group to a clade containing Rebbachisaurus, dicraeosaurids and diplodocids and the presence of the plesiomorphic state cannot be confirmed in higher titanosauroids. Expand
The Evolutionary History of Sauropod Dinosaurs
TLDR
Forked chevrons, which have played such an important role in previous studies of sauropod phylogeny, are here considered to have evolved twice within the Sauropoda, which may reflect a correlation between chevron shape and the use of the tail as a weapon within these twosauropod families. Expand
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
