Reconstructing the ecological relationships of the latest Cretaceous Antarctic dinosaurs and how functional tooth morphology influenced diet and ecological niche among basal Ornithopod dinosaurs
… by million years. However, a group of non-avian dinosaurs from the James Ross Basin (JRB) of the Antarctic Peninsula, composed of two elasmarians, a parankylosaurian ankylosaur, a hadrosaur and a suspected megaraptor, all are represented by fragmentary remains have emerged from the same horizon …

The evolution of intraspecific variation, growth, and body size in early theropod dinosaurs
… of maturity. The growth patterns of the earliest dinosaurs (230–190 million years ago), in particular the morphological changes undergone during the life history of an individual (i.e., ontogeny) is poorly understood. To tackle this problem, I studied the changes undergone during growth of two …

Osteohistology and Growth of Edmontosaurus and Assessment of Life History Changes in Hadrosaurid Dinosaurs
… aspects in extinct organisms. Hadrosaurid dinosaurs, the dominant large-bodied terrestrial herbivores in most Late Cretaceous ecosystems, have an exceptional fossil record consisting of over 60 species and multiple ontogenetic bonebeds making them an ideal clade on which to conduct life …

Insights into the palaeobiology of sauropodomorph dinosaurs through an analysis of their bone histology
… Triassic to Early Jurassic. Many sauropodomorph dinosaurs such as Massospondylus, Melanorosaurus and Antetonitrus have been excavated from the EF. These dinosaurs range from basal Sauropodomorpha to the derived Sauropodiformes providing key insight into their evolution. Osteohistology studies are …

Unravelling the biology of the Southern African Sauropodomorph dinosaurs, Plateosauravus and the 'Maphutseng dinosaur'
The nomen dubium “Euskelosaurus ” has functioned as a waste - basket taxon for decades, with large bodied sauropodomorph material from South Africa as signed to it without proper analysis.

Evolutionary palaeoecology of the megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta, Canada
During the Late Cretaceous, megaherbivorous dinosaurs flourished in the Western Interior of North America (Laramidia). At any one time, there were typically two ankylosaurs (one ankylosaurid plus one nodosaurid), two ceratopsids (one centrosaurine plus one chasmosaurine), and two hadrosaurids (one …

The Refutation of Bird Evolution by a Study of Feathered Dromaeosaurs as a Created Kind
Secular science seeks to use a group of feathered dinosaurs known as dromaeosaurs as proof of the evolution of birds. Species evolution is not true and feathered dromaeosaurs are misclassified as dinosaurs when they are in fact neither birds nor dinosaurs but a separate animal group as first …

Afterlives of extinction : the politics of display in the modern United States
… hold on the American popular imagination. Dinosaurs, in particular, have been iconic and pervasive representatives of a planetary past for much of the twentieth century. While natural history museums are the most obvious spaces in which to encounter extinct animals, these scientific venues …

The Origin and Early Evolution of the Dinosauria
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, …

Investigating Sexual Dimorphism in Ceratopsid Horncores
… investigated in the horncores of two ceratopsid dinosaurs, Triceratops and Centrosaurus apertus. A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa …

Descrição osteológica do crânio de um novo dinossauro Prosauropoda do Neotriássico do sul do Brasil
… state. It consists on one of the most complete dinosaurs found in Brazil so far, including a partia! skull and postcranial material. The detailed description of the skull is presented here and an attempt is made to establish the phylogenetic position of this new taxon. The morphological analysis …

The Integration Of Morphology, Variation, And Phylogenetics To Better Understand Fossil Taxa And Their Modern Relatives
… are a group of dynamic, swift predatory dinosaurs, that have a sparse fossil record, particularly at the time of their extinction near the Cretaceous-Paleogene boundary. A recently recovered specimen from the latest Cretaceous of New Mexico represents a new genus and species and is the …

Innovation and corporate renewal
Leading firms fail. Dinosaurs ruled the earth for 180 million years - almost forty times longer than human beings have existed. However, the only remains are fossils and a few hardy species. Both are the result of failures to innovate fast enough in the face of changing environments. While …

Intervertebral Articulation and the Evolution of Large Body Size in Archosauria
Dinosaurs are the largest animals to ever walk on the continents and some reached body sizes of up to 70 tons. Observation of their closest living relatives, birds and crocodylians, could never allow for prediction of gigantic dinosaurian forms. Therefore, the fossil record is crucial to …

Disease in the Cretaceous: a comparative study of Iguanodon and hadrosaur palaeopathology
Ornithopod dinosaurs show one of the highest 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 …

A cognitive poetics of the threat scene: How movies scare us

From Gondwanaland, with love : the tale of how Boston got its rocks
… of Pangaea, and the rise and fall of the dinosaurs. More than that, though: the history of our understanding of Boston's journey illustrates how geologists think about their world, and how their ideas have changed over the last 150 years in one of science's great revolutions.
