I am a Professor of Palaeobiology working mainly on pterosaurs, theropod dinosaurs and exceptional preservation of fossil vertebrates. I am particularly interested in the Cretaceous with projects on the dinosaurs of the Isle of Wight, the Kem Kem Beds of Morocco and the palaeoecology of the Crato Formation, Brazil. In addition, I work on the vertebrate palaeontology of two Jurassic mud-rock sequences: the Oxford and Kimmeridge clay formations
My work in Morocco stems from a collaboration with Dr Nizar Ibrahim of the University of Chicago, who works on Cretaceous dinosaur faunas, and has a special interest in the gigantic fish-eating Spinosaurus. My work in Brazil in mainly in collaboration with Dr Paulo Brito of the Estadual University of Rio de Janeiro, with whom I have worked for more than twenty years.
