Abstract:
Despite numerous studies, the thermal physiology of dinosaurs remains unresolved. Thus, perhaps the commonly asked question whether dinosaurs were ectotherms or endotherms is inappropriate, and it is more constructive to ask which dinosaurs were likely to have been endothermic and which ones ectothermic. Field data from crocodiles over a large size range show that body temperature fluctuations decrease with increasing body mass, and that average daily body temperatures increase with increasing mass. A biophysical model, the biological relevance of which was tested against field data, was used to predict body temperatures of dinosaurs. However, rather than predicting thermal relations of a hypothetical dinosaur, the model considered correct paleogeographical distribution and climate to predict the thermal relations of a large number of dinosaurs known from the fossil record (>700). Many dinosaurs could have had “high” (>30°) and stable (daily amplitude >2°) body temperatures without metabolic heat production even in winter, so it is unlikely that selection pressure would have favored the evolution of elevated resting metabolic rates in those species. Recent evidence of ontogenetic growth rates indicates that even the juveniles of large species (3000–4000 kg) could have had biologically functional body temperature ranges during early development. Smaller dinosaurs (<100 kg) at mid to high latitudes (>45°) could not have had high and stable body temperatures without metabolic heat production. However, elevated metabolic rates were unlikely to have provided selective advantage in the absence of some form of insulation, so probably insulation was present before endothermy evolved, or else it coevolved with elevated metabolic rates. Superimposing these findings onto a phylogeny of the Dinosauria suggests that endothermy most likely evolved among the Coelurosauria and, to a lesser extent, among the Hypsilophodontidae, but not among the Stegosauridae, Nodosauridae, Ankylosauridae, Hadrosauridae, Ceratopsidae, Prosauropoda, and Sauropoda.

Abstract:
Dinosaurs were large-bodied land animals of the Mesozoic that gave rise to birds. They played a fundamental role in structuring Jurassic–Cretaceous ecosystems and had physiology, growth, and reproductive biology unlike those of extant animals. These features have made them targets of theoretical macroecology. Dinosaurs achieved substantial structural diversity, and their fossil record documents the evolutionary assembly of the avian body plan. Phylogeny-based research has allowed new insights into dinosaur macroevolution, including the adaptive landscape of their body size evolution, patterns of species diversification, and the origins of birds and bird-like traits. Nevertheless, much remains unknown due to incompleteness of the fossil record at both local and global scales. This presents major challenges at the frontier of paleobiological research regarding tests of macroecological hypotheses and the effects of dinosaur biology, ecology, and life history on their macroevolution.

Abstract:
Abstract The timing of non-avian dinosaur decline is one of the most debated subjects in dinosaur palaeontology. Dinosaur faunas from the last few million years of the Mesozoic appear far less diverse than those from earlier in the Cretaceous, a trend that could suggest non-avian dinosaur extinction occurred gradually. However, the limited nature of the latest Cretaceous dinosaur record outside western North America has obscured patterns in dinosaur diversity just before the extinction. Here, I describe two associated skeletons and several isolated fossils recovered from the New Egypt Formation of New Jersey, a latest Maastrichtian unit that underlies the K–Pg boundary. The larger skeleton appears to be a small-bodied adult from a lineage outside Hadrosauridae, the dominant group of these animals during the Maastrichtian, that persisted along the eastern coast of North America. Smaller specimens are identifiable as juvenile hadrosauromorphs. These results substantiate an important assemblage of herbivorous dinosaurs from the poorly-known Cretaceous of eastern North America. The marine depositional setting for these skeletons demonstrates that proposed ecosystem preferences among hadrosauromorphs may be biased by post-mortem transportation, and the adult skeleton has implications for assessing the proposed relictual nature of Late Cretaceous eastern North American vertebrates.

Abstract:
Abstract Network methods are widely used to represent and analyze biogeography. It is difficult, however, to convert occurrence data of fossil vertebrates to a biogeographical network, as most species were known from a single locality. A new method for creating a biogeographical network that can incorporate phylogenetic information is proposed in this study, which increases the number of edges in the network of fossil vertebrates and enables the application of various network methods. Using ancestral state reconstruction via maximum parsimony, the method first estimates the biogeographical regions of all internal nodes of a given phylogeny using biogeographical information on the terminal taxa. Then, each internal node in the phylogenetic tree is converted to an edge in the biogeographical network that connects the region(s), if unambiguously estimated, of its two descendants. The new method was applied to phylogenetic trees generated by a birth–death model. Under all conditions tested, an average of $CDATA[$CDATA[$>$$70% of the internal nodes in phylogenetic trees were converted into edges. Three network indices—link density, average link weight, and endemism index (EI)—were evaluated for their usefulness in comparing different biogeographical networks. The EI reflects the rate of dispersal; the other indices reflect nonbiogeographical parameters, the number of taxa and regions, which highlights the importance of evaluating network indices before applying them to biogeographical studies. Multiple Cretaceous biogeographical networks were constructed from the phylogenies of five tetrapod taxa: terrestrial crocodyliforms, terrestrial turtles, nonavian dinosaurs, avians, and pterosaurs. The networks of avians and pterosaurs showed similar topologies and a strong correlation, and unexpectedly high endemism indices. These similarities were probably a result of shared taphonomic biases (i.e., the Lagerstätten effect) for volant taxa with fragile skeletons. The crocodyliform network was partitioned into the Gondwanan and Laurasian continents. The dinosaur network was partitioned into three groups of continents: 1) North America, Asia, and Australia; 2) Europe and Africa; and 3) India, Madagascar, and South America. When Early and Late Cretaceous dinosaurs were analyzed separately, the dinosaur networks were divided into 1) North America, Asia, and Australia; and 2) Europe, Africa, India, and South America for the Early Cretaceous and 1) North America, Asia, and Europe; and 2) India, Madagascar, and South America for the Late Cretaceous. This partitioning of dinosaur and crocodyliform networks corroborates the results of previous biogeographical studies and indicates that the method introduced here can retrieve biogeographical signals from a source phylogeny when sufficient data are available for most targeted biogeographical regions.

Abstract:
Heterodontosaurids comprise an important early radiation of small-bodied herbivores that persisted for approximately 100 My from Late Triassic to Early Cretaceous time. Review of available fossils unequivocally establishes Echinodon as a very small-bodied, late-surviving northern heterodontosaurid similar to the other northern genera Fruitadens and Tianyulong. Tianyulong from northern China has unusual skeletal proportions, including a relatively large skull, short forelimb, and long manual digit II. The southern African heterodontosaurid genus Lycorhinus is established as valid, and a new taxon from the same formation is named Pegomastax africanusgen. n., sp. n. Tooth replacement and tooth-to-tooth wear is more common than previously thought among heterodontosaurids, and in Heterodontosaurus the angle of tooth-to-tooth shear is shown to increase markedly during maturation. Long-axis rotation of the lower jaw during occlusion is identified here as the most likely functional mechanism underlying marked tooth wear in mature specimens of Heterodontosaurus. Extensive tooth wear and other evidence suggests that all heterodontosaurids were predominantly or exclusively herbivores. Basal genera such as Echinodon, Fruitadens and Tianyulong with primitive, subtriangular crowns currently are known only from northern landmasses. All other genera except the enigmatic Pisanosaurus have deeper crown proportions and currently are known only from southern landmasses.

Abstract:
The Elliot Formation of South Africa and Lesotho contains one of the most important but relatively understudied, early ornithischian faunas; here a review is presented of its known ‘fabrosaurid’ (non-heterodontosaurid) specimens. The first ornithischian collected from the Lower Elliot Formation (Late Triassic) is described, representing a new taxon of basal ornithischian. Within the Upper Elliot Formation (Early Jurassic), ‘Fabrosaurus australis’ is considered a nomen dubium, a new diagnosis of Lesothosaurus diagnosticus is presented, and a new taxon, Stormbergia dangershoeki gen. et sp. nov., is described. A comprehensive new cladistic analysis tests global ornithischian phylogeny. Results support the generally understood framework of ornithischian interrelationships; however, support is weak for many major clades, and the positions of certain taxa differ significantly from previous analyses. The enigmatic clade Heterodontosauridae may represent some of the most basal known ornithischians. Strong evidence supports hysilophodontid paraphyly, with some Middle Jurassic taxa (Agilisaurus, Hexinlusaurus) cladding as sister taxa to Cerapoda (Marginocephalia + Ornithopoda). Biogeographical analyses support hypotheses of vicariance related to the Late Jurassic geographical isolation of Asia. Synthesis of anatomical, taxonomic, phylogenetic, and biogeographical data allows the development of a broad overview of early ornithischain evolution. Triassic ornithischians were scarce and geographically limited. Ornithischians underwent a significant increase in diversity, abundance, and geographical distribution across the Triassic-Jurassic boundary, perhaps coincident with the origin of the clade Genasauria.

Abstract:
Tanius sinensis Wiman, 1929 was one of the first hadrosauroid or “duck-billed” taxa erected from China, indeed one of the very first non-avian dinosaur taxa to be erected based on material from the country. Since the original description by Wiman in 1929, the anatomy of T. sinensis has received relatively little attention in the literature since then. This is unfortunate given the importance of T. sinensis as a possible non-hadrosaurid hadrosauroid i.e. a member of Hadrosauroidea outside the family of Hadrosauridae, living in the Late Cretaceous, at a time when most non-hadrosaurid hadrosauroids had become replaced by the members of Hadrosauridae. To gain a better understanding of the anatomy of T. sinensis and its phylogenetic relationships, the postcranial anatomy of it is redescribed. T. sinensis is found to have a mosaic of basal traits like strongly opisthocoelous cervical vertebrae, the proximal end of scapula being dorsoventrally wider than the distal end, the positioning of the ventral apex of the supra-acetabular process of the ilium, posterodorsally to the ischial peduncle, the ratio between the proximodistal length of the metatarsal III and the mediolateral width of this element being greater than 4.5. Derived traits present in T. sinensis include curved dorsal surface of the scapula, arcuate fourth trochanter of the femur, cnemial crest of the tibia extending ventrally into the proximal half of the shaft, and the distal end of the fibula expanding into a club shape in lateral view. A potential autapomorphy is noted, being the caudal fusion of the medial and lateral condyles of the femur forming a completely enclosed “tunnel”. The body mass of the holotype of T. sinensis, is also estimated, and found to have been around 2950 kg. The phylogenetic analysis agrees with previous studies placing T. sinensis as a non-hadrosaurid hadrosauroid. Furthermore, in the phylogenetic analysis, T. sinensis is recovered as non-hadrosaurid hadrosauroid, forming a clade with Bactrosaurus johnsoni Gilmore, 1933, which shares the following unambiguous synapomorphies; the width of the orbital margin of the jugal being almost equally wide to that of the infratemporal margin of the bone; the ratio between the mediolateral width of the skull roof across the postorbitals and that across the quadrate cotyli of the paired squamosals being more than 1.20.
Den här uppsatsen handlar om Tanius sinensis Wiman, 1929 som levde under Kritaperioden i  Shan-dongprovinsen i nordöstra Kina. Tanius sinensis hörde till gruppen ”Anknäbbsdinosaurier” som ut- vecklades under början av Kritaperioden för mellan 130-100 miljoner år sedan. I slutet av Kritaperi- oden för ungefär 84 miljoner år sedan så blev de ”primitiva” ”anknäbbsdinosaurierna” bortträngda av de mer ”avancerade” ”anknäbbsdinosaurierna”. Tanius sinensis är viktig på så vis att den kan ha varit en ”primitiv” ”anknäbbsdinosaurie” som överlevde vid en tidpunkt när de flesta andra ”primitiva” ”anknäbbsdinsoaurier” hade trängts undan. För att få en bättre bild av T. sinensis anatomiska känne- tecken och en bättre bild av dess släktskapsförhållanden, så ombeskrivs anatomin hos den del av skelettet som inte omfattar kraniet. En släktskapsanalys görs också baserat på de kännetecken som jag själv och tidigare forskare  har  observerat  i  skelettet.  De  anatomiska  observationerna avslöjar en mosaik av ”primitiva” och mer ”avancerade” karaktärer, som tillsammans  med släktskapsanalysenpekar  på att T. sinensis var en sent överlevande ”primitiv”  ”anknäbbsdinosaurie”.

Abstract:
The Middle Jurassic was a critical time in the evolution of theropod dinosaurs, highlighted by the origination and initial radiation of the large-bodied and morphologically diverse Tetanurae. Middle Jurassic tetanurans are rare but have been described from Europe, South America, and China. In particular, China has yielded a number of potential basal tetanurans but these have received little detailed treatment in the literature.

Abstract:
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. It does this following examination, comparison and description of early dinosaur material, and by utilising modern phylogenetic analysis techniques, to rigorously and objectively test the fundamental groupings within the clade Dinosauria using a newly compiled dataset of early dinosaurs and other dinosauromorphs (= close dinosaur relatives). The current consensus on how the principal clades within Dinosauria (Theropoda, Sauropodomorpha and Ornithischia) are related to one another is challenged by the results of these analyses. This study finds, for the first time, a sister-group relationship between Ornithischia and Theropoda, here termed Ornithoscelida. Consequently, a new definition for Dinosauria is presented, as the historic definition would exclude all members of Sauropodomorpha from the clade. As well as this, I propose revisions to the definitions of each of the principal dinosaurian sub-divisions and propose a new timeframe and geographic setting for the origin of Dinosauria. These new hypotheses force re-evaluations of early dinosaur cladogenesis and character evolution, suggest the independent acquisition of hypercarnivory in multiple dinosaur groups and offers an explanation for many of the anatomical features previously regarded as striking convergences between theropods and early ornithischians. As well as presenting new anatomical data on many early dinosaurs and dinosauromorphs, including a comprehensive re-description of the postcranial anatomy of Lesothosaurus diagnosticus (Chapter 2), and a new anatomical dataset of early dinosaurs (the largest ever compiled), this thesis goes on to implement the new dataset to investigate a number of important outstanding questions about early dinosaur evolution and provides new lines of enquiry for future workers to pursue. The results of this thesis reveal the oldest known members of the dinosaurian clades Theropoda and Sauropodomorpha (Chapter 6), as well as a new clade within Ornithischia; a taxon previously thought to represent a derived theropod has been recovered as a potential ‘missing link’ between theropods and ornithischians using the new dataset. This work now provides a unique tool for the assessment of the phylogenetic affinities of early dinosaurs and dinosauromorphs and, once published, will hopefully become the benchmark dataset for palaeontologists working in this area.

Abstract:
Parmi les dinosaures, le clade des Ornithopodes est l’un de ceux qui a rencontré le plus de succès. Apparus au Jurassique supérieur, le groupe s’est dispersé et diversifié jusqu’à sa disparition à la fin du Crétacé. Je me suis attachée à étudier le cerveau des Ornithopodes d’Europe et d’Asie, à établir des comparaisons avec les autres archosaures et de nouveaux arbres phylogénétiques incluant des caractères issus de l’endocrâne. Pour ce faire, des moulages et des reconstitutions à partir de données CT-scan ont été réalisées pour étudier la cavité endocrânienne de divers membres de ce groupe. J’ai réalisé des moulages endocrâniens en silicone de 3 taxons et les reconstructions à partir de données CT-scan de 3 autres taxons de Dinosaures Ornithopodes. Une collection unique d’endocrânes de crocodiles et d’oiseaux récents étend les possibilités de comparaison. Certains endocrânes des taxons fossiles ont confirmé les caractéristiques décrites précédemment dans la littérature, tandis que de nouveaux éléments sont apparus. Les endocrânes n’ont en effet pas seulement livré la morphologie du cerveau, mais aussi des valleculae, le détail des nerfs crâniens et de la glande pituitaire. J’ai ainsi pu étendre la présence de valleculae, qui est un indice fort en faveur d’un télencéphale développé, chez un nouvel Hadrosauroidea, alors que cela n’était connu que chez les Hadrosauridae et les membres dérivés de deux autres groupes (Theropoda et Pachycephalosauria). Le cerveau des Ornithopodes dérivés était caractérisé par des hémisphères cérébraux très larges et de forme arrondie. Les flexions crâniale et pontine sont inexistantes, à l’opposé de ce qui est observé chez les Saurischiens. Les pédoncules olfactifs étaient larges. J’ai également fourni de nouveaux exemples de l’influence de la taille de la glande pituitaire sur la taille totale de l’individu. Le cerveau des Ornithopodes a subi des changements au cours de leur évolution :le plus marquant est l’augmentation du volume des hémisphères cérébraux par rapport au reste du cerveau. J’émets l’hypothèse que cette augmentation résulte de la complexification des comportements chez les Ornithopodes.

Une nouvelle phylogénie a été établie, bénéficiant de l’apport de nouveaux caractères basés sur l’endocrâne. Elle apporte des éléments de réflexion intéressants quant à la position de plusieurs taxons d’Iguanodontia basaux. La résolution est cependant faible et d’autres études devront être menées dans le futur. Les relations de parenté ne sont pas stables et de faibles changements entraînent des différences notables dans les résultats des analyses phylogénétiques./Among the Dinosauria, Ornithopoda were one of the most successful clade. Since the Late Jurassic, they spread and diversified until the end of the Cretaceous. I studied the brain of Ornithopoda from Europe and Asia, established comparisons with other archosaurs and new phylogenetic analyses including endocranial characters. In order to do this, I made silicone endocasts of 3 taxa and virtual reconstructions from CT-scan dataset of 3 other taxa of ornithopod dinosaurs. A collection of extant crocodiles and birds allows more points of comparison. Some endocasts made on the fossil specimens confirmed previously described characteristics, while new ones were brought to our attention. The endocasts opened up not only the morphology of the brain, but also the anatomy of the cranial nerves, the pituitary gland and the presence of valleculae. This last element, evidence of a developped telencephalon, has been established in a new Hadrosauroidea species as his oldest occurrence. The brain of more derived Ornithopods was characterized by very large cerebral hemispheres. The pontine and cranial flexures disappeared, to the contrary to what is observed in Saurischians. The olfactory peduncles were large. New evidences about the correlation between the size of the pituitary gland and the size of the individual. The Ornithopod’s brain changed throughout their evolution :the most striking is the increase of the cerebral hemispheres. The complexity of behaviors exhibited by Ornithopods is suggested as the trigger of the increase of the size of the cerebral hemispheres.

A new phylogenetic analysis was established, including new characters from the endocranial cavity. It brings interesting perspectives about the position of several basal Iguanodontia. Unfortunately the resolution is weak and new studies will be needed. The relationships are not stable and small changes lead to instabilities in the result of the phylogenetic analysis.
