Inside a duck-billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia. [PDF]

Anat Rec (Hoboken)
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

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.
