155 Million Years ago, the Jurassic was truly the time of the giants: While Apatosaurus, Brachiosaurus, and Allosaurus shook the ground, the seas were also full of some of the largest animals ever. The largest fish ever known was hunted by marine predators with the biggest jaws of all time. Smaller predators were also ever-present, to snatch up the scraps!
Liopleurodon: With a head larger than any dinosaur, and long jaws lined with an impressive array of huge teeth, this flippered killer made short work of its prey. Leedsichthys: The largest fish ever to swim the seas rivaled even today's largest whales; and like them, it ate the smallest creatures of the ocean, tiny fish and plankton. Metriorhynchus: Small but manoeuvrable, this 10-foot long flippered crocodile was ideally suited to look after itself. Smooth-skinned, with a tail like a fish, it was perfectly adapted to life at sea, fishing for its meals.
