The Origin and Early Evolution of the Dinosauria
… looks at the earliest evolution of the clade Dinosauria by focusing upon the interrelationships of the major subsidiary clades within it. It does this following examination, comparison and description of early dinosaur material, and by utilising modern phylogenetic analysis techniques, to …

The Phylogeny of Basal Coelurosaurian Theropods (Archosauria: Dinosauria) and Patterns of Morphological Evolution during the Dinosaur-Bird Transition
… a flurry of research on early birds and their dinosaurian relatives, however, several questions still remain. First, the anatomy of some major theropod groups has yet to be described in detail. Second, there is little consensus on the phylogenetic relationships of the basal members of a …

Morfologia do esqueleto apendicular e das cinturas peitoral e pélvica dos Titanosauridae (Dinosauria: Sauropoda) do neocratáceo de Minas Gerais, Brasil
… bones referred to the family Titanosauridae (Dinosauria: Sauropoda) are described and figured. They have been found in Continental Upper Cretaceous strata of Brazil (Bauru Basin), near the city of Peirópolis, state of Minas Gerais. All of them were collected, together with vertebrae and three …

Reweaving the tapestry: a supertree of birds
… an updated species-level supertree of the Dinosauria was also constructed and used to look at diversification rates in order to elucidate the “Cretaceous explosion of terrestrial life”. Results from this study show that this apparent burst in diversity at the end of the Cretaceous is a …

Rise of present-day tetrapods in the paleotropics of Late Triassic equatorial Pangaea: new insights from microvertebrate data
… Testudinata, Crocodylomorpha, and Dinosauria). With few exceptions, only the LTF assemblage survives the end-Triassic Extinction (~201.5 Ma), highlighting the Late Triassic (~227–201.5 Ma) record as essential for understanding this pivotal transition and the evolutionary and …

Disease in the Cretaceous: a comparative study of Iguanodon and hadrosaur palaeopathology
… frequencies of palaeopathological lesions in the dinosaurian fossil record. However, a systematic overview of distribution of palaeopathologies in the clade has not been undertaken, and this thesis aims to report an extensive review of them and identify possible ecological and behavioural …

Quantifying variation in teeth of Late Triassic vertebrates: implications for identification, palaeoecology, and biostratigraphy
… and identify isolated teeth, particularly within Dinosauria, but 3D methods have been underutilised, despite the increasing availability of scanned fossils and increased information on dimensionality that can be captured by using 3D models. My dissertation quantified variation in tooth …
