| As the last great carnivore of the Cretaceous Period, Tyrannosaurus rex was an efficient killing machine stalking the North American landscape. With a specially strengthened nose structure that enabled it to deliver bone splintering, crushing bites to both captured prey and during combat with others of its species, a Tyrannosaurus rex lower jaw could deliver 10,000 newtons of force – the equivalent of being able to lift a semi-trailer. | ||
