Everyone is familiar with the dinosaurs and how they lived long ago on our planet. But there were other creatures who existed and some even long before the dinosaurs. There were even creatures who ate other dinosaurs as they started to appear.
From giant and scary cousins of millipedes to creatures so bizarre that it’s hard to believe they even existed, we take a look at 10 Terrifying Prehistoric Creatures That Actually Existed.
10. Jaekelopterus rhenaniae – This creature was a giant predator and belong to a group of now extinct sea scorpions called Eurypterids. They were some of the largest arthropods that ever lived with some fossils showing the Jaekelopterus could reach up to 8 feet long.
9. Helicoprion – It’s 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 you were on a different planet.
8. Gigantopithecus – This was the largest ape which once roamed the early prehistoric forests and jungles. Some fossils found indicate that this giant-sized ape stood as high as 10 feet tall and weighed as much as 1,300 pounds. It is believed that it existed between 9 million and even as recently as 100,000 years ago.
7. Arthropleura was an herbivorous arthropod that lived in what is now northeastern North America and Scotland around 315 to 299 million years ago, during the late Carboniferous Period. And what made this creature terrifying was its size, its appearance, and how fast it could move. Fossilized footprints from Arthropleura have been found in many places.
6. Livyatan melvillei is the name of a prehistoric whale inspired by the biblical sea monster Leviathan. It existed around 10 million years ago. It was a member of a group of hyper-predatory macro raptorial sperm whales or raptorial sperm whales and was likely an apex predator preying on whales, seals, and anything else unfortunate to get in front of its mouthful of 14-inch-long enamel coated teeth.
5. Smilodon – Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats. Smilodon was more robustly built than any extant cat, with particularly well-developed forelimbs and exceptionally long upper canine teeth.
4. Deinosuchus – is an extinct genus related to the alligator that lived 80 to 73 million years ago during the late Cretaceous period. Its name means ‘terrible crocodile’ and that is exactly what it was. The research was done when fossilized feces and oddly bitten bones of dinosaurs were found next to the fossils of this living creature.
3. Quetzalcoatlus is a pterosaur which lived approximately 70 million to 65 million years ago during the Late Cretaceous Period. But these creatures were not like the Pterodactyl. They were more like a Giraffe that walked on all 4 limbs but had wings or webs between the legs.
2. Titanoboa is an extinct genus of snakes and whose name means ‘titanic boa’. Fossils of this massive boa have been found that date back 60 million years ago. A fossil was found in Columbia that was so large that is stunned scientists and forced them to rethink the nature of prehistoric life.
1. T-Rex – What can be said about the mighty Tyrannosaurs Rex that hasn’t already been said. Tyrannosaurus Rex, or T-Rex for short was one of the largest known carnivorous dinosaurs. Its name means ‘King of the Tyrant Lizards’.
