Description
Granaria sp.
(Fig. 23)
Material examined. BSPG 1952 VIII 46 (1 spcm.), 47 (2 spcm.).
Description. Shell small, with acuminated spire top. Protoconch (1½ whorl) narrow, rounded, smooth; transition to teleoconch unclear. Whorl profile convex. Suture deep. Teleoconch sculptured by regularly distributed, very fine prosocline ribs; distance between ribs approximately twice rib width.
Previous identification of the material. Gall (1980: Nr. 31): Cochlostoma sp.
Discussion. Only spire fragments remain and thus a more precise identification is not possible. The regular whorl growth and the fine, straight and regular ribs indicate the genus Granaria (Höltke & Rasser 2013). Moreover, the present specimens are indistinguishable from the Granaria sp. described from the Middle Miocene (MN 5) of Sandelzhausen, southeastern Germany (Salvador 2014).
Paleoecological remarks. Recent Granaria species prefer dry and open habitats, usually calcareous (Welter- Schultes 2012).
