Relive the excitement of National Geographic's newest 3-D adventure, Sea Monsters, with this eye-popping T-shirt.

Prehistoric marine reptiles, both alien and awe-inspiring, at once utterly inhuman and somehow irresistibly compelling. Nothing can prepare you for this amazing plunge into the Cretaceous oceans of 80 million years ago, a merciless realm ruled by some of the most ferocious animals ever to stalk the seas of planet Earth. It scarcely seems possible that these swift, massive underwater predators actually existed, but they did, and they're depicted here in breathtaking detail. 100% cotton. Machine wash. Imported.
