Fossils have been found from Vancouver Island in British Columbia, Canada, as well as from the Izumi Group of Japan. These finds date back to the late Santonian stage and the late Campanian to the late Maastrichtian, respectively, of the Late Cretaceous. Kourisodon was originally described as a member of the "Leiodontini", more recently as a "Clidastine".
