Sea Monsters: Prehistoric Creatures of the Deep (National Geographic)

The official companion to the giant screen film Sea Monsters: A Prehistoric Adventure.

The terrors of today's oceans have got nothing on the fearsome marine reptiles of the ancient seas, the kind featured in Sea Monsters: Prehistoric Creatures of the Deep. Take a trip back 82 million years in time to when long-necked plesiosaurs, enormous fish, giant turtles, hungry sharks, and fierce mosasaurs - the most dangerous predators of them all - ruled the waters of a giant inland sea that split North America in half. Meet the pioneering paleontologists who uncovered the fossils of these amazing creatures. More than 100 striking images taken straight from the film - many in 3-D - bring them all to life, from the fast swimming Dolichorhynchops to the graceful, long-necked Styxosaurus. This official film companion promises to be an unforgettable trip to the waters of the prehistoric past, giving an up-close look at the fascinating world of sea monsters.
