New titanosaur remains from the Portezuelo Formation (Turonian–Coniancian) and their implications for the sauropod faunal diversity of the southern Neuquén Basin, Patagonia, Argentina
A Sauropodomorph (Dinosauria, Saurischia) Specimen from the Upper Triassic of Southern Brazil and the Early Increase in Size in Sauropodomorpha
ABSTRACT Whereas sauropod dinosaurs from the Jurassic and Cretaceous Periods were the largest land animals that ever lived, some of their early relatives evolved relatively large bodies during the…
A new giant sauropod, Australotitan cooperensis gen. et sp. nov., from the mid-Cretaceous of Australia
TLDR
A detailed comparative and preliminary computational phylogenetic assessment supports a shared ancestry for all four Winton Formation taxa, albeit with limited statistical support.
Sauropod dinosaur teeth from the lower Upper Cretaceous Winton Formation of Queensland, Australia and the global record of early titanosauriforms
The Upper Cretaceous Winton Formation of Queensland, Australia, has produced several partial sauropod skeletons, but cranial remains—including teeth—remain rare. Herein, we present the first…
Paleoenvironmental contexts of South American Cretaceous sauropod tracks
First titanosaur dinosaur nesting site from the Late Cretaceous of Brazil
Titanosaurs were successful herbivorous dinosaurs widely distributed in all continents during the Cretaceous, with the major diversity in South America. The success of titanosaurs was probably due to…

The Earliest Known Titanosaur Sauropod Dinosaur
TLDR
The presence of a basal titanosaurian sauropod in the lowermost Cretaceous of Patagonia supports the hypothesis that the group was established in the Southern Hemisphere and reinforces the idea of a Gondwanan origin for Titanosauria.
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.
The skull of the titanosaur Tapuiasaurus macedoi (Dinosauria: Sauropoda), a basal titanosaur from the Lower Cretaceous of Brazil
TLDR
The effects of missing data and missing stratigraphic ranges on results are explored, concluding that (1) when missing data levels are high, resolution of even small amounts of that missing data can have dramatic effects on topology, (2) taxa that are mostly scored for characters that cannot be scored in other taxa may be topologically unstable and (3) there were several suboptimal trees that had greatly improved stratig graphic fit with relatively little compromise in terms of tree length.
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 the…
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.
Reassessment of Laplatasaurus araukanicus (Sauropoda: Titanosauria) from the Upper Cretaceous of Patagonia, Argentina
Abstract. The original material assigned to Laplatasaurus araukanicus Huene come from five different localities in northern Patagonia (Argentina) where the Upper Cretaceous (Campanian) lies…
The Appendicular Skeleton of Neuquensaurus, a Late Cretaceous Saltasaurine Sauropod from Patagonia, Argentina
Neuquensaurus, from the Late Cretaceous of Argentina and one of the first dinosaurs described from Patagonia, is one of the most derived sauropod dinosaurs, and its proportions and size place it…
The oldest titanosaurian sauropod of the Northern Hemisphere
TLDR
Discovery of Volgatitan gen. nov. suggests that the lithostrotian lineage leading to the Lognkosauria had a wider distribution in the Early Cretaceous and became extinct everywhere except South America by the end of the EarlyCretaceous.
A new basal titanosaur (Dinosauria, Sauropoda) from the Lower Cretaceous of Brazil
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.
