There are no superpredators in the modern ecosystem. It is difficult for us to imagine an animal 14 meters long and weighing under 10 tons attacking herbivores of comparable size. That was the most famous predator of all time - the Tyrannosaurus Rex. Remarkable discoveries have been made in recent years in the study of the paleobiology of tyrannosaurs and other dinosaurs. Dozens of new dinosaur species are described each year. This book is an incredibly interesting and truly scientific journey of 100 million years, from the Middle Jurassic to the end of the Cretaceous. In it, renowned tyrannosaurus specialist David Hawn provides the most complete picture of the evolution and all aspects of the life of these amazing ancient reptiles and their contemporaries in the light of the latest paleontological research.
