Ornithischian and theropod dinosaurs were morphologically diverse during the Cretaceous. In contrast, sauropods were relatively more conservative. The anatomy of Bonitasaura salgadoi, a new 9-m titanosaurian sauropod from Upper Cretaceous beds of Patagonia, suggests that sauropod anatomical diversity would have included unexpected items. Its unusual, rectangular lower jaw possesses narrow, anteriorly restricted teeth and shows evidence of a sharp keratinous sheath over the non-dentigerous… 

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

A reassessment of Mongolosaurus haplodon Gilmore, 1933, a titanosaurian sauropod dinosaur from the Early Cretaceous of Inner Mongolia, People's Republic of China

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.

A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria

A number of distinctive morphologies—such as the ossified cervical tendon, extremely pneumatized cervical vertebrae, and a habitually downward-facing snout—that have rarely, if ever, been documented in other titanosaurs are documented, thus broadening the understanding of the anatomical diversity of this remarkable sauropod clade.

A Reappraisal of the Late Cretaceous Argentinean Sauropod Dinosaur Argyrosaurus superbus, with a Description of a New Titanosaur Genus

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.

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

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 the sauropod dinosaur Jainosaurus (= "Antarctosaurus") septentrionalis from the Upper Cretaceous of India

Early evaluations of sauropod diversity in the Cretaceous of India recognized three genera, “Titanosaurus,” Antarctosaurus, and Laplatasaurus, each of which was thought to have closely related

A new rebbachisaurid sauropod from the Aptian–Albian, Lower Cretaceous Rayoso Formation, Neuquén, Argentina

L. 2018. A new rebbachisaurid sauropod from the Aptian– Albian, Lower Creta ceous Rayoso Formation, Neuquén, Argentina. Acta Palaeontologica Polonica 63 (X): xxx–xxx. Rebbachisaurids are a group of

A large Cretaceous theropod from Patagonia, Argentina, and the evolution of carcharodontosaurids

It is suggested that carcharodontosaurid radiated in Gondwana sharing with spinosaurids the role of top-predators until their extinction in Cenomanian–Turonian times, and offers a better understanding of the evolution of Southern theropod faunas.

A new titanosaur sauropod from the Late Cretaceous of Brazil.

The phylogenetic position of Brasilotitan nemophagus is difficult to establish, the new species is neither a basal nor a derived member of the Titanosauria and, based on the lower jaw morphology, appears to be closely related to Antarctosaurus wichmannianus and Bonitasaura salgadoi.

A cladistic comparison of the segnosaurs with thecodonts and early dinosaurs of the Triassic suggests that, despite their late appearance, the seGNosaurs are phylogenetic intermediates between herbivorous prosauropods and early ornithischians.

The phylogenetic relationships of the Nemegtosauridae (Saurischia, Sauropoda)

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.

Sauropod dinosaur phylogeny: critique and cladistic analysis

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.


Abstract Rapetosaurus krausei (Sauropoda: Titanosauria) from the Upper Cretaceous Maevarano Formation of Madagascar is the best-preserved and most complete titanosaur yet described. The skull of

Early Evolution and Higher-Level Phylogeny of Sauropod Dinosaurs

The cladistic analysis presented here focuses on higher-level relationships among sauropods, and identifies Neosauropoda as a new taxon that includes Haplocanthosaurus, Camarasaurus, and Titanosauriformes.

Cretaceous sauropods from the sahara and the uneven rate of skeletal evolution among dinosaurs

Lower Cretaceous fossils from central Niger document the succession of sauropod dinosaurs on Africa as it drifted into geographic isolation. A new broad-toothed genus of Neocomian age ( approximately

Palaeontology: The beaks of ostrich dinosaurs

Two new ornithomimid specimens in which soft-tissue structures of the beak have been preserved are described, indicating that these creatures probably used their beaks to strain food sediment in an aqueous environment, rather than for predation on large animals.


"The titanosaurid skull is interpreted as Camarasaurus-Iike, but with ""peg-like"" teeth restricted to the extremity of the jaws, which exhibit wear facets sharply inclined with respect to the
