"Meet six mega beasts. The spinosaurus, megalania, terror bird, acrocanthosaurus, mosasaur and the bear dog were all fierce, gruesome and relentless predators. Each episode is a detective story, bringing the mega beast back to life from fossil clues and modern analogues. From the evidence, scientists reveal how these mysterious creatures functioned and behaved, what they looked like, how they fought, what they ate-- and what ate them. It also demonstrates what these creatures of enormous size would look and act like if they still roamed the planet with us today."--Container.
