This species is usually considered to be the ancestor of the extant Oliva flammulata Lamarck, 1811. It is known from the Oligocene (Aquitaine Basin. France (Chattian)) and Miocene (North Sea Basin. Belgium. Germany. The Netherlands; Aquitaine Basin. France. Aquitanian-Burdigalian-Serravallian; Eastern/Central Paratethys. Bulgaria. Italy. Turkey (Serravallian); Canary Islands.

European Miocene "Oliva" are commonly attributed to this species, with no other distinct species recognised. As expressed by Lozouet et al (op cit.) it is possible that several distinct species exist in the Upper Oligocene-Lower Miocene of France.
