(Source: shughal)

For 135 million years, dinosaurs were the undisputed rulers of the Earth, and could still have been today if not for a cataclysmic comet some 65 million years ago. However, our planet has been around for a lot longer than the dinosaurs’ reign and, as it turns out, nature is quite adept at producing nightmare-inducing monsters. To think that dinosaurs are the only scary inhabitants of our prehistoric past would be a mistake.

First discovered in Germany, Dakosaurus had a fishy-reptilian body. You wouldn’t want to be in the same room as this creature.

Also known as Spiral Saw, this ghost shark had tight curled-up coil of triangular teeth. Can you imagine being bitten by it?
