Overview:Insects and other invertebrates have always fascinated Nigel and the remote Scottish Island of Arran offers him some clues about one of the Park’s next guests. The rocks of the island date back some 300 million years and reveal fossilized tracks of an Arthropleura: a giant arthropod, much like our millipede and centipedes today, only this one grew to the size of a man. Not only giant centipedes but also oversized scorpions and dragonflies populated a hot and boggy Scotland, which, at that time, sat on the Equator.
