(O.) wunnenbergi Hoffmann, 1968 Dactylioceras commune has shells reaching a diameter of . Usually the average diameter reach about , while the average width is . In these small but strong shells ribs run straight or are slightly convex across the venter. These ribs are quite coarse on the outer whorls and finer on the inner whorls. The whorl section is as round as a circle.
