National Geographic's giant-screen film Sea Monsters: A Prehistoric Adventure
brings to life the extraordinary marine reptiles of the dinosaur age in both 3-D and 2-D. Eighty million years ago, the American Midwest lay under a great inland sea where colossal creatures ruled the waves. From giraffe-necked Styxosaurus and sea birds with teeth to the T-Rex of the ocean -- the 40-foot super-predator Tylosaurus -- these wondrous beasts defy imagination. In a remarkable journey, National Geographic immerses audiences in this unexplored world of the "other dinosaurs," delivering the creatures brought to life on the world's biggest screen.
