DIAGNOSIS

“Coquille ovale, oblongue, comprimée, lisse, anguleuse au pourtour, formée de neuf loges étroites presque droites, triangulaires, non saillantes réunies au centre sans former de dépression ombilicale. La dernière loge, convexe en dessus, forme un triangle assez aigu. L’ouverture est semi-lunaire, très étroite” (d’Orbigny 1846).

Papp & Schmid (1985) reported that vial 74 of the Vienna collection contains Nonion commune , described by d’Orbigny in Nussdorf material, and some Nonionella . No lectotype of Nonion commune was designated.

A mount in the French d’Orbigny collection labelled Nonionina communis (MNHN FO 96) contains 11 specimens. These specimens originate from Baden and therefore do not belong to the type series. We described herein the fourth left hand specimen which is the best preserved.The test,slightly reddish in colour (diagenesis?)is ovate.The final whorl has 12 chambers increasing in size as added, the final one being elongate. The periphery is little angled, the sutures are recessed, and the umbilical area is somewhat depressed and filled with granular material. The apertural face is elongate with some granules above the apertural slit.

This species has been widely cited in the literature (for example 42 references between 1826 and 1929 reported in Ellis & Messina 1940). As suggested by its name, this species has a large geographical and stratigraphical distribution: probably Eocene to Recent according to Cicha et al. (1998). This species has also been reported in the Paleocene of Aquitaine: it appears in the upper Selandian (souszone P 4a, Sztràkos 2005) and it becomes common from the basal Ypresian ( Sztràkos 2000).

In 1846 d’Orbigny had already pointed out the similarities and differences between Nonionina communis and N. boueana , and wrote about the last one “Cette espèce, par son pourtour anguleux, se rapproche du N. communis , mais il s’en distingue par sa forme plus élargie, par ses loges plus arquées et plus convexes, ainsi que par sa dépression ombilicale”. SEM observations reveal the existence of a depressed umbilical area with pustules in both species. Thus, we think that they mainly differ by the chamber shapes which are more elongate in Nonion commune ( Fig. 3J View FIG ).
