The Titanosaur Sauropods from the late Campanian–early Maastrichtian Allen Formation of Salitral Moreno, Río Negro, Argentina [PDF]

, 2013
The dinosaur record of the Salitral Moreno locality (Río Negro Province, Argentina) is characterized by a high diversity of herbivore taxa, among them hadrosaurs, ankylosaurs, and titanosaur sauropods, but carnivores are rare, consisting of only a few ...

Sauropod dinosaur teeth from the lower Upper Cretaceous Winton Formation of Queensland, Australia and the global record of early titanosauriforms

Royal Society Open Science, 2022
The Upper Cretaceous Winton Formation of Queensland, Australia, has produced several partial sauropod skeletons, but cranial remains—including teeth—remain rare.

HEAD, SKULL–NECK AND EXTRINSIC EYE MUSCULATURE OF THE DICRAEOSAURID SAUROPOD BAJADASAURUS PRONUSPINAX

Publicación Electrónica de la Asociación Paleontológica Argentina
Cranial muscles perform important roles triggering diverse paleobiological faculties, such as feeding, communication, alert postures, etc. Within Sauropoda, a clade with high specializations in skull architectures, and several partially complete skulls ...

Standing giants: a digital biomechanical model for bipedal postures in sauropod dinosaurs

Palaeontology, Volume 68, Issue 4, July/August 2025.
ABSTRACT Here we explore the potential of sauropod dinosaurs to adopt a bipedal or tripodal stance using digital biomechanical modelling and finite element analysis (FEA). Seven sauropod species from diverse lineages and sizes were sampled, and 3D models of their femora were analysed under both extrinsic (body weight distribution) and intrinsic ...

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 ...

On a dicraeosaurid specimen from the Mulichinco Formation (Valanginian, Neuquén Basin) of Argentina and phylogenetic relationships of the South American dicraeosaurids (Sauropoda, Diplodocoidea)

Comptes rendus. Palevol, 2022
The osteology of Pilmatueia faundezi Coria, Windholz, Ortega & Currie, 2019, a dicraeosaurid sauropod from the Lower Cretaceous of Patagonia, is reassessed from the perspective of a new specimen (MLL-Pv-010) that provides additional information on the ...

Description of a new specimen of Haplocanthosaurus from the Dry Mesa Dinosaur Quarry

The Anatomical Record, Volume 307, Issue 12, Page 3782-3800, December 2024.
Abstract A new specimen of Haplocanthosaurus is described based on bones excavated from the Late Jurassic Dry Mesa Dinosaur Quarry near Delta, Colorado. The specimen consists of seven dorsal vertebrae and a right tibia and is identified as Haplocanthosaurus based on the dorsally angled transverse processes, tall neural arch peduncles, low parapophyses ...

Cautionary tales on the use of proxies to estimate body size and form of extinct animals

Ecology and Evolution, Volume 14, Issue 9, September 2024.
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...
