The largest prehistoric sea scorpion, Eurypterids, was more than 7-feet long - and was almost 1,000 times the weight of the largest scorpion alive today.
Over the course of nearly half a billion years, which deadly predator ranks as the biggest and baddest? Join us as we travel through time and across the world to present this terrifying top ten ranking. We uncover new evidence, put theories to the test, and feature icons like the Tyrannosaurus rex and the saber-toothed cat, plus lesser-known beasts like the terror bird and the giant lizard Megalania.
