''Dicerodiscus'' is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the early part of the Botomian stage,〔 in China (Guizhou and Sichuan). Four species have been assigned to it. ''Dicerodiscus'' is unique for an eodiscoid in having conspicuous and curved spines that are attached anteriorly, and at their base are directed outward perpendicular to the midline, before gradually bending further backwards. == Distribution ==
