When it comes to creepy crawly things, the smaller the better. Even though the smaller ones give me the willy's too, it's hard to see them. So, out of sight, out of mind, right?

So, the bigger the better? No, in this case, there is such a thing as too big.

What if the creepy things with lots of legs that move very fast, big teeth, long antennas, and sharp pinchers were seven feet long? No!

But, that is exactly what used to live in some parts of the world and probably all over. The fossils just haven't been found yet.

Meet the stuff of nightmares, the giant millipede.

Having lived during the Carboniferous Period, from 359.2 to 299 million years ago, these giant millipedes dominated swampy forests long before the dinosaurs.

During this period, their role in the forest would have been that of a predator, with, according to Ranker, no known predators of its own. That would mean that this giant millipede was the king of the forest.

The answer we could have, but we didn't. World Building says that humans could have lived during this land-based prehistoric period.

Yes. Fossil evidence has been found in both Kentucky and New Mexico. According to Ranker,

Since a complete fossil has yet to be found in Kentucky, only fragments, the giant millipedes could have measured over nine feet in length.
