Dinosaurs have been a source of fascination ever since their discovery in England early in the 19th century. Before their extinction, dinosaurs dominated Earth's terrestrial habitats for about 160 million years, far longer than primates. Dinosaurs present the ultimate puzzle in forensic science, but we have learned a great deal about them in the last 50 years. This lecture series will explain the evolutionary and ecological relationships among dinosaurs, what it might have been like to be present in the Mesozoic Era, and the question of what ultimately brought about the total extinction of all dinosaurs at the end of the Cretaceous Period. Although extinct, dinosaurs have never been more a focus of science than they are today.
