Status Mintz (1968: p. 1287-1288) elevated the Pourtalesiidae to ordinal rank "in recognition of their unique morphology and the present inability to relate them to any of the other recognized orders". Today it is clear that pourtalesiids are derived urechinid holasteroid echinoids and the order Pourtalesioida is not used in recent classifications. [details]
