Some 230 million years ago, in the Mesozoic Era, wonderful creatures appeared on the Earth: dinosaurs. Carnivores and herbivores, sea and land reptiles and flying creatures dominated a primordial landscape, warm and humid, perfect for the development of life. There was only one undisputed ‘king’ of the dinosaurs: the Tyrannosaurus rex. With its sharp teeth, sturdy legs and long tail, it is the most famous and fearsome predator of all time.
