Top 6 Mid-Boggling Prehistoric Beasts

Extreme Millipede — Arthropleura

Millipedes are very creepy, but they would become horrifying if some mad scientist decided to make them a thousand times larger. That’s basically what the 8-feet-long Arthopluera was like 290 million years ago. As you can imagine, this nightmare bug was so big it didn’t have a single natural predator. The Arthropleura was not big on hunting either and preferred munching on juicy fruits and seeds on the ground.
