A genus-level supertree of the Dinosauria [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002 One of the ultimate aims of systematics is the reconstruction of the tree of life. This is a huge undertaking that is inhibited by the existence of a computational limit to the inclusiveness of phylogenetic analyses. Supertree methods have been developed

RICHARD OWEN’S DINOSAURIA IN CONTEXT: THE RHETORIC, POLITICS AND LEGACY OF THE DINOSAURS [PDF]
Earth Sciences HistoryOne of the most famous achievements of Richard Owen is his naming of the Dinosauria in 1842. During the Geological Society meeting of 1824, William Buckland (1784– 1856) described and named Megalosaurus, the first of three extinct reptiles that would ...

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

The Osteology of Haya griva (Dinosauria: Ornithischia) from the Late Cretaceous of Mongolia
Bulletin of the American Museum of Natural History, 2021 Haya griva is an early-diverging neornithischian (“hypsilophodontid”) dinosaur known from several well-preserved skulls and articulated postcranial skeletons, in addition to dozens of partial or isolated finds from the Upper Cretaceous Khugenetslavkant ...

The Origin and Early Evolution of the Dinosauria
, 2018 For 130 years dinosaurs have been divided into two distinct clades – Ornithischia and Saurischia. This dissertation looks at the earliest evolution of the clade Dinosauria by focusing upon the interrelationships of the major subsidiary clades within it.

Evolution of hind limb morphology of Titanosauriformes (Dinosauria, Sauropoda) analyzed via 3D geometric morphometrics reveals wide-gauge posture as an exaptation for gigantism [PDF]
eLifeThe sauropod hind limb was the main support that allowed their gigantic body masses and a wide range of dynamic stability adaptations. It was closely related to the position of the center of masses of their multi-ton barrel-shaped bodies and experienced ...
