By the end of the Cretaceous, dinosaurs had lived on Earth for more than 150 million years. They occupied every continent, from the equator to near the north and south poles. The last of the plant-eating dinosaurs included the ceratopsians and the hadrosaurs, and the last of the meat-eating dinosaurs included the very large and successful Tyrannosaurus rex.
