Arthropleura

Kingdom: Animalia

Phylum: Arthropoda

Subphylum: Myriapoda

Class: Arthropleuridea

Order: Arthropleurida

Family: Arthropleuridae

Genus: Arthropleura

Arthropleura size ranged from 0.3 meters to 2.6 meters making it the largest land invertebrate known to man. It lived during the late carboniferous dying out at the beginning of the Permian as the environment started to dry out. Do to no mouth parts being preserved in any of the specimens what Arthropleura ate is under debate though plant matter found in coprolites seems to suggest that it was an herbivore. The class has "diplosomy, paranotal tergal lobes separated from the axis by sclerotized plates buttressing the leg insertions." The body had 30 pairs of legs on eight segments; tracks are found in Scotland and the northeastern United States that are about 50 cm wide.
