Abstract Sauropod dinosaurs are rare in the Cretaceous North American fossil record in general and are absent from that record for most of the Late Cretaceous. Sonorasaurus thompsoni from the Turney Ranch Formation of the Bisbee Group of Arizona, USA, potentially represents one of the youngest sauropods before their ca. 30-million-year-long hiatus from the record. The anatomy of Sonorasaurus has only been briefly described, its taxonomic validity has been questioned, several hypotheses have… 

A possible brachiosaurid (Dinosauria, Sauropoda) from the mid-Cretaceous of northeastern China

An isolated sauropod maxilla from the middle Cretaceous Longjing Formation of the Yanji basin of northeast China is reported, providing the most convincing evidence to date that brachiosaurids dispersed into Asia at some point in their evolutionary history.

The earliest known titanosauriform sauropod dinosaur and the evolution of Brachiosauridae

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.

An unusual new sauropod dinosaur from the Late Cretaceous of Mongolia

The preferred phylogenetic analysis places Abdarainurus as a basal titanosaurian sauropod, but this result could be affected by inadequate knowledge of basal titanosaurs.

Redescription of Brachiosaurid Sauropod Dinosaur Material From the Upper Jurassic Morrison Formation, Colorado, USA

It is estimated that B. altithorax had a slower tooth replacement rate than Camarasaurus or the diplodocoids it shared Morrison Formation landscapes with, which suggests a difference in diet and/or feeding strategy.

The appendicular skeleton of the dwarf macronarian sauropod Europasaurus holgeri from the Late Jurassic of Germany and a re-evaluation of its systematic affinities

An extensive re-evaluation of the systematic position of Europasaurus was done based on the three most substantial data sets published in recent years, which resolvedEuropasaurus as a basal camarasauromorph in all cases, but brachiosaurid affinities remain plausible, especially considering the heterochronic evolution of the taxon.

Osteology of Klamelisaurus gobiensis (Dinosauria, Eusauropoda) and the evolutionary history of Middle–Late Jurassic Chinese sauropods

Anatomical comparisons of the cervical vertebrae of Klamelisaurus to several other sauropodomorphs and insights from myological studies of extant archosaurs strongly suggest that this latter structure is an epaxial muscle scar that is distinct from pneumatic structures of the lateral surface of the neural spine.

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

New information on the Cretaceous sauropod dinosaurs of Zhejiang Province, China: impact on Laurasian titanosauriform phylogeny and biogeography

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.




The specimen described herein shows some clear brachiosaurid homologies that are both distinctly different from Pleurocoelus and from brachesaurids phylogenetically closer to the type Upper Jurassic Brachiosaurus, and a new taxonomic designation at the genus level is warranted.

A Sauropod Dinosaur Pes from the Latest Cretaceous of North America and the Validity of Alamosaurus sanjuanensis (Sauropoda, Titanosauria)

ABSTRACT Complete sauropod pedes are rare in the fossil record, which has limited their use in systematics. We describe a nearly complete, large sauropod pes from the Maastrichtian-age Naashoibito

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

Postcranial axial skeleton of Europasaurus holgeri (Dinosauria, Sauropoda) from the Upper Jurassic of Germany: implications for sauropod ontogeny and phylogenetic relationships of basal Macronaria

The postcranial axial skeleton of sauropods is extremely modified with respect to the anatomy observed in its ancestors, the ‘prosauropods’, proving to be one of the most informative regions of the body.

Revision of the sauropod dinosaurs of the Lower Cretaceous Trinity Group, southern USA, with the description of a new genus

Cladistic analysis indicates that Astrophocaudia and Sauroposeidon are members of Somphospondyli, whereas Cedarosaurus is a brachiosaurid.

Osteology of the Late Jurassic Portuguese sauropod dinosaur Lusotitan atalaiensis (Macronaria) and the evolutionary history of basal titanosauriforms

The results support the generic separation of the contemporaneous taxa Brachiosaurus, Giraffatitan, and Lusotitan, with the latter recovered as either a brachiosaurid or the sister taxon to Titanosauriformes.

The Beginning of the Sauropod Dinosaur Hiatus in North America: Insights from the Lower Cretaceous Cloverly Formation of Wyoming

ABSTRACT We redescribe and present newly excavated sauropod material from the Lower Cretaceous Cloverly Formation of Wyoming that we refer to the titanosauriform Sauroposeidon proteles. In contrast

Osteology of Huabeisaurus allocotus (Sauropoda: Titanosauriformes) from the Upper Cretaceous of China

A detailed redescription of Huabeisaurus allocotus is presented and a suite of anatomical comparisons with other titanosauriforms that demonstrate its validity via autapomorphies are presented, suggesting that euhelopodids exemplified a comparably broad range of feeding strategies and perhaps diets.

A New Sauropod: Tastavinsaurus Sanzi Gen. Et Sp. Nov. from the Early Cretaceous (Aptian) of Spain

In the cladistic analysis, Tastavinsaurus is the sister-taxon of the North American Venenosaurus within Titanosauriformes, which includes the Brachiosauridae, Somphospondyli, and Titanosaurusia.

Cranial anatomy of the Late Jurassic dwarf sauropod Europasaurus holgeri (Dinosauria, Camarasauromorpha): ontogenetic changes and size dimorphism

All the autapomorphic characters of Europasaurus recognized in the skull are considered to have evolved through paedomorphosis, which resulted in the dwarf condition of this taxon.
