Sauropod Trackway Morphometrics: An Exploratory Study Using Highway A16 Excavation at the Courtedoux-Tchâfouè Track Site (Late Jurassic, NW Switzerland)

Frontiers in Earth Science, 2022
Ichnogeneric classification of sauropod trackways is determined using qualitative and quantitative descriptions of morphological parameters. More recently, the validity of several of these parameters has been called into question (e.g., trackway gauge ...

The Tail of the Late Jurassic Sauropod Giraffatitan brancai: Digital Reconstruction of Its Epaxial and Hypaxial Musculature, and Implications for Tail Biomechanics

Frontiers in Earth Science, 2020
Dinosaur locomotion and biomechanics, especially of their pelvic girdles and hindlimbs, have been analyzed in numerous studies. However, detailed volumetric musculoskeletal models of their tails are rarely developed.

Bite and tooth marks on sauropod dinosaurs from the Morrison Formation [PDF]

PeerJ, 2023
Tooth-marked bones provide important evidence for feeding choices made by extinct carnivorous animals. In the case of the dinosaurs, most bite traces are attributed to the large and robust osteophagous tyrannosaurs, but those of other large carnivores ...

Cranial osteology of Bajadasaurus pronuspinax (Sauropoda, Dicraeosauridae)

Historical Biology, 2023
The cranial remains of the holotype of the Lower Cretaceous Bajada Colorada Formation (Neuquén, Argentina) Bajadasaurus pronuspinax and its associated 3D model are studied and compared herein. These materials comprise a complete braincase, skull roof and occiput, several periorbital elements, several palatal elements, a partially complete upper jaw and

What's inside a sauropod limb? First three‐dimensional investigation of the limb long bone microanatomy of a sauropod dinosaur, Nigersaurus taqueti (Neosauropoda, Rebbachisauridae), and implications for the weight‐bearing function

Palaeontology, Volume 66, Issue 4, July/August 2023., 2023
Abstract Various terrestrial tetrapods convergently evolved to gigantism (large body sizes and masses), the most extreme case being sauropod dinosaurs. Heavy weight‐bearing taxa often show external morphological features related to this condition, but also adequacy in their limb bone inner structure: a spongiosa filling the medullary area and a rather ...

Articulated bone sets of manus and pedes of Camarasaurus (Sauropoda, Dinosauria) [PDF]

Palaeontologia Electronica, 2015
Skeletons of sauropods are rarely found with fore and hind feet, and until now, only one specimen of this clade has been reported with all four autopodia preserved complete and articulated. This makes interpretations on their locomotion difficult and proper assignments of footprints to genus- or even species-level taxa are generally impossible ...

Taxonomic and stratigraphic update of the material historically attributed to Megalosaurus from Portugal [PDF]

Acta Palaeontologica Polonica
The first paleontological works on Mesozoic vertebrates from Portugal, carried out from the end of the 19th and the first half of the 20th century, provided the discovery of significant collections of vertebrate fossils.

A nearly complete skull of the sauropod dinosaur Diamantinasaurus matildae from the Upper Cretaceous Winton Formation of Australia and implications for the early evolution of titanosaurs

Royal Society Open Science, 2023
Titanosaurian sauropod dinosaurs were diverse and abundant throughout the Cretaceous, with a global distribution. However, few titanosaurian taxa are represented by multiple skeletons, let alone skulls.
