    Two views of an olive snail Amalda glandiformis. Exact locality is Höllerkogel-18 in my own documentation. It is a tiny outcrop (about 1-2 square meters) in a densely wooded, very steep area southwest of St. Josef, Styria, Austria. This small outcrop, composed of a medium grained, quartz-rich, somewhat limonitic sand yielded, from November 2016 to May 2018, at least 80 species of gastropods and bivalves and is far from exhausted. Most of the fossils are characterized by a partial limonitic staining and usually a very good preservation. The species A. glandiformis is among the most abundant in this outcrop.


    The sediments in the area belong to the "Florianer Schichten", which are part of the western Styrian basin at the eastern margin of the Alps. The "Florianer Schichten" are about 15 Ma old (Langhian, or "Badenian" in Paratethys stratigraphic terms).
