For millions of years, a massive shark more than twice as huge as the modern-day great white shark cruised the depths of the ocean, attacking and devouring prey. Fossil remains reveal megalodon to have been more than fifty feet long, with razor-sharp teeth, each the size of a human hand, and jaws so large it could swallow prey larger than a common dolphin. Fluid, detailed watercolors accompany this account of one of the most incredible creatures to inhabit our world.
