Fossils of Cordylodus have been found in Argentina, Australia, Canada (Quebec), China, Colombia (Tarqui, Huila),[2] Kazakhstan, Malaysia, Mexico, Norway, the Russian Federation, Sweden, and the United States, in the states of Alaska, Minnesota, Nevada, New York, Oklahoma (Bromide Formation), Vermont and Wyoming.[3]

C. horridus has been recovered from the Blakely Sandstone and C. angulatus from the Collier Shale, Ordovician geologic formations in the Ouachita Mountains of Arkansas and Oklahoma.
