Titanosauriforms represent a diverse and globally distributed clade of neosauropod dinosaurs, but their inter-relationships remain poorly understood. Here we redescribe Lusotitan atalaiensis from the Late Jurassic Lourinha Formation of Portugal, a taxon previously referred to Brachiosaurus. The lectotype includes cervical, dorsal, and caudal vertebrae, and elements from the forelimb, hindlimb, and pelvic girdle. Lusotitan is a valid taxon and can be diagnosed by six autapomorphies, including… 

Re-Assessment of the Late Jurassic Eusauropod Dinosaur Hudiesaurus sinojapanorum Dong, 1997, from the Turpan Basin, China, and the Evolution of Hyper-Robust Antebrachia in Sauropods

Phylogenetic analyses confirm that Hudiesaurus is a CMT and the sister taxon of Xinjiangtitan, and links the convergent evolution of robust antebrachia and an enlarged olecranon in CMTs, titanosaurs, and some ornithischians to a more flexed orientation of the forearm, an enhanced role for the forelimb in locomotion, and an anterior shift in the whole-body center of mass.

New data of the Portuguese brachiosaurid Lusotitan atalaiensis (Sobral Formation, Upper Jurassic)

The present comparative study and the phylogenetic analyses suggest the assignation of Lusotitan to Brachiosauridae supported by the presence of pronounced and dorsoventrally short deltopectoral crest, short ischiatic contribution to the acetabulum and radius length/tibia length ratio >1.

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 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.

Osteological revision of the holotype of the Middle Jurassic sauropod dinosaur Patagosaurus fariasi Bonaparte, 1979 (Sauropoda: Cetiosauridae)

ABSTRACT Middle Jurassic sauropod taxa are poorly known, due to a stratigraphic bias of localities yielding body fossils. One such locality is Cerro Cóndor North, Cañadón Asfalto Formation,

Osteology of the dorsal vertebrae of the giant titanosaurian sauropod dinosaur Dreadnoughtus schrani from the Late Cretaceous of Argentina

The dorsal sequence of Dreadnoughtus provides valuable insight into serial variation along the vertebral column of these enormous sauropods, including the variable presence of divided spinodiapophyseal laminae and associated spinodiapsisal fossae.



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.

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.

Andesaurus delgadoi gen et sp. nov. (Saurischia-Sauropoda), dinosaurio Titanosauridae de la formacion Río Limay (Albiano-Cenomaniano), Neuquen, Argentina

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.

Osteology and Relationships of Olorotitan arharensis, A Hollow-Crested Hadrosaurid Dinosaur from the Latest Cretaceous of Far Eastern Russia

The holotype of Olorotitan arharensis from the Maastrichtian Udurchukan Formation in Kundur, Far Eastern Russia, is the most complete dinosaur discovered in Russia and one of the best preserved

New Anatomical Information on Rhoetosaurus brownei Longman, 1926, a Gravisaurian Sauropodomorph Dinosaur from the Middle Jurassic of Queensland, Australia

Preliminary cladistic analysis confirms that Rhoetosaurus is a non-neosauropod gravisaurian, although weak support for the most parsimonious topology suggests further findings are required to improve upon incompleteness in the character data.

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.

The significance of Suuwassea emilieae (Dinosauria: Sauropoda) for flagellicaudatan intrarelationships and evolution

The postparietal foramen shared by Suuwassea, Dicraeosaurus, Tornieria and Amargasaurus may correlate to preferred existence in near‐shore, terrestrial environments and thus sheds light on the evolutionary origins of the Flagellicaudata.


An articulated specimen of the titanosaurian sauropod Epachthosaurus sciuttoi from the early Late Cretaceous Bajo Barreal Formation of Chubut Province, central Patagonia, Argentina is described.

The Osteology of Chubutisaurus insignis Del Corro, 1975 (Dinosauria: Neosauropoda) from the ‘Middle’ Cretaceous of Central Patagonia, Argentina

The phylogenetic analysis presented here resolves Chubutisaurus as the most basal somphospondylian.
