Ancient Monsters That Once Roamed Earth

Warning. These ancient monsters were absolutely real. The Titanoboa was

a snake so massive it could swallow a crocodile whole. Fifty feet long, weighing over a

ton, slithering through prehistoric Colombia sixty million years ago.

But that's nothing compared to Megalodon. This shark was sixty feet of pure nightmare, with teeth the size

of your hand. It hunted whales like we hunt fish. Then there's the Terror Bird.

Eight feet tall, couldn't fly, but could run you down at forty miles per hour.

Its beak could crack skulls with a single strike. The scariest part? These creatures

dominated Earth for millions of years. We've only been here for a blink.
