Hypothetical lung structure of Brachiosaurus (Dinosauria: Sauropoda) based on functional constraints [PDF]
Fossil Record, 1999 Comparison of avian and crocodylian lung structure suggests a basic archosaurian structural type, consisting of four rows of chambers that radiate independently from an intrapulmonary bronchus.

A possible brachiosaurid (Dinosauria, Sauropoda) from the mid-Cretaceous of northeastern China [PDF]
PeerJ, 2021 Brachiosauridae is a lineage of titanosauriform sauropods that includes some of the most iconic non-avian dinosaurs. Undisputed brachiosaurid fossils are known from the Late Jurassic through the Early Cretaceous of North America, Africa, and Europe, but ...

A diverse Late Cretaceous vertebrate tracksite from the Winton Formation of Queensland, Australia [PDF]
PeerJ, 2021 The Upper Cretaceous ‘upper’ Winton Formation of Queensland, Australia is world famous for hosting Dinosaur Stampede National Monument at Lark Quarry Conservation Park, a somewhat controversial tracksite that preserves thousands of tridactyl dinosaur ...

A new eusauropod (Dinosauria, Sauropodomorpha) from the Middle Jurassic of Gansu, China [PDF]
Scientific ReportsSauropod dinosaurs were gigantic quadrupedal herbivores. They range from Early Jurassic to Late Cretaceous and have been found on all continents. The rich sauropod faunas in the Middle and Late Jurassic of China are mainly from southern or western China.

A new mamenchisaurid sauropod dinosaur from the upper jurassic of Southwest China reveals new evolutionary evidence from East Asian eusauropods [PDF]
Scientific ReportsEast Asian non-neosauropodan eusauropods have been central to the study of the evolution of Middle to Late Jurassic sauropod dinosaurs. Despite their remarkable diversity, the fragmentary condition of many taxa and the insufficiency of phylogenetic data ...

Posture and mechanics of the forelimbs of Brachiosaurus brancai (Dinosauria: Sauropoda) [PDF]
Fossil Record, 1999 The posture and mechanics of the forelimbs of Brachiosaurus brancai were analysed with the help of biomechanical models. Peak forces in the joints due to acceleration of the fraction of body weight carried on the shoulder joints are critical in models ...

A new mamenchisaurid from the Upper Jurassic Suining Formation of the Sichuan Basin in China and its implication on sauropod gigantism [PDF]
Scientific ReportsThe Sichuan Basin has yielded abundant sauropod dinosaurs from the Middle-Late Jurassic, and Mamenchisauridae had predominated the dinosaur faunae during the Late Jurassic in the Sichuan Basin.

A path to gigantism: Three-dimensional study of the sauropodomorph limb long bone shape variation in the context of the emergence of the sauropod bauplan. [PDF]
J Anat, 2022 Our study investigates the limb long bone shape variation of a large sample of sauropodomorph dinosaurs in the context of the emergence of the sauropod bauplan. We highlight a differential emergence of sauropod‐related features, that appear abruptly in the forelimb bones and more gradually in the hindlimb ones.

Palaeobiology and osteohistology of South African sauropodomorph dinosaurs. [PDF]
J AnatWe found that the transitionary Sauropodiformes show both the traits of rapid growth of derived Sauropoda as well as interrupted growth of early branching Sauropodomorpha. There appears to be much more variation in growth dynamics of Sauropodiformes than initially thought.

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs. [PDF]
Anat Rec (Hoboken)Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.
