Imagine a millipede that's as long as a car and weighs over 100 pounds. This isn't a scene from a horror movie, but a real creature that lived millions of years ago. Meet Arthropleura, the largest arthropod ever discovered. Fossils have shown that these giants roamed the Earth around 346 million years ago and vanished about 50 million years later. They've left scientists puzzled about their relation to today's tiny millipedes and centipedes.

Recently, a team of paleobiologists in France took a closer look at these ancient critters. They scanned well-preserved fossils of juvenile Arthropleura and used special imaging techniques to recreate their faces. The results? These prehistoric giants shared some facial features with today's millipedes and centipedes. They had seven-segmented antennae and a special neck part called a collum.

The findings suggest that centipedes and millipedes are more closely related than previously thought. But there's still a lot we don't know about Arthropleura. Scientists aren't sure exactly what they ate or how they breathed. Some think they might have been aquatic or spent time in different environments.

So, next time you spot a millipede in your garden, remember it's part of a long line of creepy crawlies that once ruled the Earth. And be glad they're tiny now!
