Fossils have been found Mazon Creek USA, Piesberg in Germany and in the Kirov Oblast region, and the Kamensk-Shakhtinsky of Russia.[1][2][3][4]
A. antiqua is estimated to have a body length of about 2.17 cm[2] and may have preyed upon insects and other smaller animals that lived alongside them. A. wolterbeeki is the oldest spider known from Germany.[3]
