10 Terrifying Prehistoric Creatures

From giant and terrifying centipede cousins to creatures so strange that it's hard to believe they even existed, let's take a look at the 10 terrifying prehistoric creatures that actually existed.

10. Jaekelopterus rhenaniae: this creature was a giant predator and belonged to a group of extinct marine scorpions called Eurypterids. They were some of the greatest arthropods that ever lived with some fossils showing that Jaekelopterus could reach up to 8 feet in length.

9. Helicoprion: it is interesting to see how far evolution has come. For example, if we look at today's sharks and the sharks that existed during prehistoric times, you would think of being on another planet.
