It does not matter if the Arthropleura was a herbivore. This 9-feet long invertebrate could send chills down your spine.
If you were to visit North America or Scotland in the Carboniferous era, you would be surprised to see the land crawling with the Arthropleura.
Holding resemblance to almost any crawling arthropod, this creature crawled its way to extinction years ago. You will never again see a huge arthropod with numerous legs in your nearby woods.
