There are no superpredators in our modern ecosystem. It is difficult for us to imagine an animal 14 meters long and weighing 10 tons attacking herbivores of comparable size. This is exactly what the most famous predator of all time was, the Tyrannosaurus rex. In recent years, remarkable discoveries have been made in the study of the paleobiology of tyrannosaurs and other dinosaurs. Dozens of new species of dinosaurs are described every year. This book is an incredibly interesting and truly scientific journey spanning 100 million years, from the Middle Jurassic to the end of the Cretaceous. In it, the famous expert on tyrannosaurs, David Hawn, gives the most complete understanding 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.
