Abstract. A new titanosaur sauropod from the Upper Cretaceous of Neuquén is described, Choconsaurus baileywillisi gen. et sp. nov. The species is represented by a nearly complete series of dorsal vertebrae as well as other parts of the skeleton. The material comes from the locality of Villa El Chocón and stratigraphically from the Huincul Formation, whose age has been estimated as upper Cenomanian. The new taxon presents many autapomorphic features, including the presence of a small notch on… 

Baalsaurus mansillai gen. et sp. nov. a new titanosaurian sauropod (Late Cretaceous) from Neuquén, Patagonia, Argentina.

A dentary of a new titanosaur sauropod, Baalsaurus mansillai, is described from the Late Cretaceous of Patagonia, Argentina represented by an "L" shaped dentary with three apomorphic characters that are not present in other taxa: dentary alveoli with 10 teeth in the anterior ramus.

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

Osteology of the Wide-Hipped Titanosaurian Sauropod Dinosaur Savannasaurus elliottorum from the Upper Cretaceous Winton Formation of Queensland, Australia

ABSTRACT The titanosaurian sauropod dinosaur Savannasaurus elliottorum is represented by a partial postcranial skeleton from the lower Upper Cretaceous (Cenomanian–lowermost Turonian) Winton

Two Late Cretaceous sauropods reveal titanosaurian dispersal across South America

This study describes two new titanosaurians from Quebrada de Santo Domingo (La Rioja, Argentina) and suggests nesting site philopatry among Titanosauria and that this clade was spread throughout southern South America at the end of the Late Cretaceous.

Two Late Cretaceous sauropods reveal titanosaurian dispersal across South America

South American titanosaurians have been central to the study of the evolution of Cretaceous sauropod dinosaurs. Despite their remarkable diversity, the fragmentary condition of several taxa and the

A new giant sauropod, Australotitan cooperensis gen. et sp. nov., from the mid-Cretaceous of Australia

A detailed comparative and preliminary computational phylogenetic assessment supports a shared ancestry for all four Winton Formation taxa, albeit with limited statistical support.

An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade.

The results of four recent, largely independent analyses support the existence of a derived titanosaurian lineage distinct from the 'Saltasaurinae line,' which is herein termed Colossosauria.

Ten more years of discovery: revisiting the quality of the sauropodomorph dinosaur fossil record

Spatiotemporal changes in fossil specimen completeness can bias our understanding of a group's evolutionary history. The quality of the sauropodomorph fossil record was assessed a decade ago, but the

A good part of the postcranial skeleton of an Albian-Cenomanian primitive titanosaurid from Patagonia is described and discussed, and it is argued that the latter were endemic and very diversified, representing the major herbivorous group of the Late Cretaceous fauna of Gondwana.

Postcranial Anatomy of Bonitasaura salgadoi (Sauropoda, Titanosauria) from the Late Cretaceous of Patagonia

The appendicular anatomy of Bonitasaura supports referral to Titanosauria based on characters such as the semilunar sternal plates, flat and rugose distal surfaces of the metacarpals, medial curvature of the proximal femur, posterior shallow fossa of the astagalus undivided, and mediolaterally expanded distal tibia.

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.

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.

The new mid-sized sauropod is related to Rebbachisaurus and Limaysaurus because of the presence of several synapomorphies, which support its inclusion in a separate clade of basal Diplodocoidea, the ReBBachisauridae.
