Sixty-five million years ago, a world that belonged to the dinosaurs suffered a cosmic catastrophe, obliterating the kingdom of Tyrannosaurus rex. For the sixty-five million years folllowing, the bones of the last king of the dinosaurs lay hidden. Then, at the turn of the 20th Century, scientists began to coax the first fragments from the badlands of western North America. They found a super-carnivore that stood eighteen feet tall and was forty feet from head to tail. Today, the bones of Tyrannosaurus rex allow us to encounter the greatest meat-eating machine of the prehistoric world, and T. rex has become the most famous of all the dinosaurs, an ultimate expression of savagery and power.
