The Gorgosaurus, or "fierce lizard," didn't have to worry about being hunted 77 million years ago when it terrorized the Earth. A cousin of Tyrannosaurus rex, the dinosaur could stretch to 30 feet and weigh as much as three tons. Armed with a mouthful of double-serrated teeth, it had no trouble stabbing and slashing the flesh of its prey.
