Acidiscus Rasetti, 1966,[2] is a genus of Eodiscinid trilobite belonging to the family Weymouthiidae Kobayashi T. (1943),[3] Order Agnostida Salter (1864).[4] It lived during the Botomian stage[1] = late Lower Cambrian Stage 4 (upper of two stages subdividing the unnamed Series 2); the upper Botomian boundary corresponds to base of the Middle Cambrian, Miaolingian Series and Wuliuan stage.
