The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The Anatomical Record, EarlyView.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Journal of Anatomy, EarlyView.PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.

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.

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 ...

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 ...

Anais da Academia Brasileira de Ciências, 2018 We describe a dentary of a new titanosaur sauropod, Baalsaurus mansillai, gen. et sp. nov. from the Late Cretaceous of Patagonia, Argentina. The material comes from the Portezuelo Formation, Neuquén Group.

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 ...
