13 Terrifying Prehistoric Monsters. You Won’t Sleep After This.
After looking at these freaky creatures, I doubt humanity could have survived if we’d been around during the prehistoric ages. These monsters look like they’re straight out of a horror movie. What makes it freakier is that they were real at one point…maybe they’ll come back someday…

Lived 60 milloin years ago. At its largest size it could be up to 42 feet long and 2,500 pounds (12.8 meters, 1133kilo)


3. Meganeura Monyi
Basically a monster dragon fly with a foot long wing span.
4. Jaekelopterus Rhenaniae
