Millipedes 'as big as cars' once roamed Northern England, fossil discovery reveals

Millipedes "as big as cars" once roamed Northern England, a fossil discovery by scientists at the University of Cambridge has revealed. The species apparently roamed what is now Northern England during the Carboniferous period - around 100 million years before the age of the dinosaurs. The fossil reveals the creature, called Arthropleura, was the largest-known invertebrate animal of all time.
