An extinct genus of giant millipede-like arthropods from the Carboniferous period, reaching lengths of up to 8 feet.
From arthro- (jointed) + pleura (from Greek pleura, side or rib). The scientific name references the segmented, jointed body structure and the lateral pleural plates characteristic of these ancient creatures.
Arthropleura roamed ancient forests 300 million years ago and could grow as long as a person is tall—imagine encountering an 8-foot armored arthropod in a dark cave; these creatures remind us that arthropod body plans are incredibly successful at enormous scales.
