Body masses of some South American dinosaurs are estimated. The sauropod Argentinosaurus huinculensis reached 73 tonnes, and therefore, is the largest of all land animals whose mass has been rigorously obtained. Another sauropod, Antarctosaurus giganteus, was the second largest, at nearly 69 tonnes, while Antarctosaurus wichmannianus reached 34 tonnes. A third sauropod, the bizarre-looking Amargasaurus cazaui, was much smaller, with a body mass of only 2.5 tonnes. Among theropods, the body mass… Expand
A Gigantic, Exceptionally Complete Titanosaurian Sauropod Dinosaur from Southern Patagonia, Argentina
TLDR
Dreadnoughtus is the most complete giant titanosaur yet discovered, and provides new insight into the morphology and evolutionary history of these colossal animals. Expand
Report of a giant titanosaur sauropod from the Upper Cretaceous of Neuquén Province, Argentina
Abstract One of the most fascinating research topics in the field of sauropod dinosaurs is the evolution of gigantism. In the particular case of Titanosauria, the record of multi-ton species (thoseExpand
The First Giant Titanosaurian Sauropod from the Upper Cretaceous of North America
Argentinosaurus (Cenomanian, Argentina) is generally accepted as being the largest dinosaur so far discovered and is one of several giant titanosaurian sauropods known from the Upper Cretaceous ofExpand
Body size evolution in Titanosauriformes (Sauropoda, Macronaria)
TLDR
It is shown that there is no increase or decrease in titanosauriform body size with age along the Cretaceous and that negative changes in body size are more common than positive ones (although not statistically significant) for most of the titanosuriform subclades (e.g. Saltasaridae, Lithostrotia, Titanosauria and Somphospondyli).

BIGGEST OF THE BIG: A CRITICAL RE-EVALUATION OF THE MEGA-SAUROPOD AMPHICOELIAS FRAGILLIMUS COPE, 1878
TLDR
The estimated 2.7 m height of the dorsal suggests a skeleton 58 m long, about 9.25 m at the highest point of the back, and with a body mass of 122,400 kg, which indicates that A. fragillimus was several orders of magnitude larger than any other sauropod. Expand
Osteohistology of Rapetosaurus krausei (Sauropoda: Titanosauria) from the Upper Cretaceous of Madagascar
TLDR
The largest known Rapetosaurus was still growing, whereas some small juveniles exhibit an unusual pattern of bone erosion and replacement in the context of peripheral lines of arrested growth that signal a temporary pause in bone apposition, and it is hypothesize that these signals may relate to the drought-stressed ecosystem inhabited by Rapetaurus.

A New Titanosaur (Dinosauria, Sauropoda) from the Upper Cretaceous (Cerro Lisandro Formation) of Mendoza Province, Argentina
Abstract. Quetecsaurus rusconii gen. et sp. nov. is a new titanosaur (Dinosauria, Sauropoda) from the Neuquén Basin of Mendoza Province, Argentina. The specimen comes from red mudstones of theExpand
The fragile legacy of Amphicoelias fragillimus (Dinosauria: Sauropoda; Morrison Formation - Latest Jurassic)
TLDR
It is concluded that the reported size of A. fragillimus is most likely an extreme over-estimation, based on the ontogenetic change of Diplodocoidea vertebrae, the science of gigantism, and Cope’s own mannerisms. Expand
Overosaurus paradasorum gen. et sp. nov., a new sauropod dinosaur (Titanosauria: Lithostrotia) from the late Cretaceous of Neuquén, Patagonia, Argentina.
TLDR
Analysis of the phylogenetic relationships of Overosaurus places it within the Aeolosaurini, as the sister taxon of a monophyletic group formed by Aeolosaurus rionegrinus, A. maximus, Gondwanatitan faustoi and Pitekunsaurus macayai. Expand

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.

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

ON THE PALAEOBIOLOGY OF THE SOUTH AMERICAN HORNED THEROPOD CARNOTAURUS SASTREI BONAPARTE
TLDR
It is concluded that Car- notaurus was an agile theropod, with a somewhat fast rather than strong bite, and that it must have used the horns in intraspecific fights or even in hunting. Expand
