Pulmonoscorpius

Name means: “lung scorpion”
Eats: Other bugs and small animalsPrehistoric giantsPrehistoric8 legsNot a bug of today, but a prehistoric giant

Pulmonoscorpius was a giant scorpion that lived on land about 341 million years ago, long before the dinosaurs. The biggest one we know of was about 70 centimetres long, as long as a big dog. It had big eyes on the sides of its head and probably hunted in the daytime.

This one died out a very long time ago. It is one of the most famous bugs of prehistoric times, so it gets a place in Bug Wiki too.
