Discus sp.

( Fig. 22)

Material examined. BSPG 1952 XVIII 41 (3 spcm.).

Description. Shell diminutive, discoid. Protoconch (~1¼ whorl) flat, smooth; transition to teleoconch clear. Teleoconch sculptured by fine but well-marked parallel prosocline ribs; distance among ribs equal to width of rib. Whorl profile convex. Suture well-marked. Whorls regularly growing.

Previous identification of the material. Gall (1980: Nr. 9): Discus sp.

Discussion. The material is very fragmentary, but a generic assignment is possible by the distinct shell shape and sculpture pattern. Moreover, the well-marked sculpture compare well with D. pleuradrus (Bourguignat) , a species widespread during the Middle and Upper Miocene of Central Europe ( Böttcher et al. 2009).

Paleoecological remarks. Recent European species live in damp woodlands or grasslands ( Welter-Schultes 2012).
