Era of giant insects. Fossils show that giant dragonflies and huge cockroaches were common during the Carboniferous period which lasted from about 359 to 299 million years ago. During the Carboniferous period at the end of the Paleozoic era there were insects of very different magnitudes than those we know today. The Protodonata is an example of an order of extinct giant insects.

They were flying looking similar to dragonflies and some of them were as big as an eagle. Thanks to the fragments of wings recovered we know that some of them reached up to 28. The Paleozoic era occurred 542 to 250 million years ago.

It is divided into six periods of time and the last two saw the development of the largest insects. These were known as the Carboniferous period 360 to 300 million years ago and the Permian period 300 to. PBS Member Stations rely on viewers like you.

It would have been a moist swampy place covered in endless fields of timber and giant ferns crawling with Lovecraftian insects the size of your arm or larger. Insects can really seem huge especially when you are afraid of them. Still some of them are actually much smaller today than their ancestors from prehistor.

Anomalocaris canadensis looked like a strange blend of squid and shrimp. It was three feet 10 m long with a mouth full of razor-sharp teeth. Fossils found in China show that it was a massive undersea arthropod that lived about 500 million years ago.

But then they were reborn again only their size was much smaller than before. Over time and the evolution of life these insects have gradually become the size they are now. Today insects are among the smallest creatures on Earth but about 300 million years ago huge bugs were fairly common.
