Tyrannosaurus rex, whose name means “king of the tyrant lizards,” was one of the most ferocious predators to ever walk the Earth. Its keen sense of smell to detect prey, coupled with powerful jaws and sharp teeth made it the perfect predator.
Triceratops lived in herds to warn each other of danger and reduce their chances of being singled out by a predator. Their horns and formidable neck frill made them perfectly built to protect themselves against carnivorous dinosaurs such as the tyrannosaurs rex.
While some people outside the scientific community still refer to Apatosaurus as Brontosaurus, the name Brontosaurus was actually the result of a fossil mix-up. It is believed to be one of the largest land animals to have roamed the Earth.
