Arthrolycosa (meaning "wolf [spider] with joints") is an extinct genus of spiders that lived about 300-250 million years ago from the late Carboniferous to the late Permian.
Fossils have been found Mazon Creek USA and in the Kirov Oblast region of Russia.
Species of Arthrolycosa are estimated to have grown to a body length of 2.17 cm, and may have preyed upon insects and other smaller animals that lived alongside them.
