Vertebral pneumaticity, air sacs, and the physiology of sauropod dinosaurs
Abstract The vertebrae of sauropod dinosaurs are characterized by complex architecture involving laminae, fossae, and internal chambers of various shapes and sizes. These structures are interpretedExpand

SAUROPOSEIDON PROTELES, A NEW SAUROPOD FROM THE EARLY CRETACEOUS OF OKLAHOMA
Abstract Sauroposeidon proteles, a new brachiosaurid sauropod, is represented by an articulated series of four mid-cervical vertebrae recovered from the Antlers Formation (Aptian–Albian) ofExpand

Head and Neck Posture in Sauropod Dinosaurs Inferred from Extant Animals
The neck posture of sauropod dinosaurs has long been controversial. Recent reconstructions position the cervical vertebrae and skull in an “osteological neutral pose” (ONP), the best fit arrived atExpand

Among extant tetrapods, pneumatic postcranial bones are only present in birds, and they are osteological correlates of the diverticular lungs and pulmonary air sacs. The presence of postcranialExpand

Postcranial Skeletal Pneumaticity in Sauropods and Its Implications for Mass Estimates
of sauropods, and one of the cornerstones of our fascination with them, is their apparent efficiency of design. The presacral neural spines of all sauropods have a complex of bony ridges or platesExpand

Caudal Pneumaticity and Pneumatic Hiatuses in the Sauropod Dinosaurs Giraffatitan and Apatosaurus
Skeletal pneumaticity is found in the presacral vertebrae of most sauropod dinosaurs, but pneumaticity is much less common in the vertebrae of the tail. We describe previously unrecognized pneumaticExpand

WHAT PNEUMATICITY TELLS US ABOUT ‘PROSAUROPODS’, AND VICE VERSA
Pneumatic (air-filled) bones are an important feature of the postcranial skeleton in pterosaurs, theropods and sauropods. However, there is no unambiguous evidence for postcranial pneumaticity inExpand

A Ceratopsian Dinosaur from the Lower Cretaceous of Western North America, and the Biogeography of Neoceratopsia
The fossil record for neoceratopsian (horned) dinosaurs in the Lower Cretaceous of North America primarily comprises isolated teeth and postcrania of limited taxonomic resolution, hampering previousExpand
