THE TYRANT

Widely regarded as the king of the dinosaurs, Tyrannosaurus rex weighed up to 9 tons (about twice as much as an African elephant) and was as long as a school bus. It could apply all its force to jaws that were powerful enough to crush a car with up to 6.5 tons of pressure. No animal since has had a comparably powerful bite. If there is ever a real Jurassic Park someday, T. rex would certainly be the highlight—if anyone is brave enough to visit.
