Fun for the whole family — now brought to life through captivating 3-D!  Journey 80 million years back in time to an age when mighty dinosaurs dominated the land — and an equally astonishing assortment of ferocious creatures swam, hunted, and fought for survival beneath the vast, mysterious prehistoric seas. Stunning, photo-realistic imagery re-creates the perilous underwater realm of two young, dolphin-sized marine reptiles called Dolichorhynchops, or Dollies, and follows their incredible journey through waters ruled by some of the most awesome predators ever to prowl the Earth’s oceans. Interweaving ground-breaking fossil finds from around the globe with cutting-edge computer-generated re-creations, National Geographic’s powerful storytelling immerses you in the life-or-death drama of an age when monsters ruled the seas! With original music by Peter Gabriel and The Footnote, and narrated by Liev Schreiber. Seen originally in IMAX® and other specialty theaters. Includes four pairs of 3-D glasses.
