Bithynia sp. (Fig. 3) Material examined. BSPG 1952 XVIII 18 (3 opercula). Previous identification of the material. Gall (1980: Nr. 34): Bithynia (Bithynia) cf. glabra (Zieten). Discussion. The only fossils of this genus in the material from Gündlkofen are opercula; their overall shape and concentric growth pattern indicate the genus Bithynia, but identification at species level is impossible. Paleoecological remarks. Recent Bithynia species live in richly vegetated slow moving or standing waters, some are also found in temporary water bodies (Welter-Schultes 2012).
