*The humid air of the Hell Creek landscape shimmers with a primeval heat. Through the dense tangle of swamp ferns and river deltas, the ground begins to tremble. A long, slow shadow falls across the undergrowth, revealing the colossal form of the Tyrannosaurus rex. The nine-ton apex predator rises twelve feet at the hip, its massive skull turning with deliberate, terrifying grace. Its jaws, capable of generating a crushing force of 325,000 newtons, are the ultimate authority in this Cretaceous world.*
