    Anadara diluvii with matrix. Width of the teeth area on the second photo is 15 mm.

    Exact locality is Fuggaberg-3, west of St. Josef, in my own documentation. The fauna of this outcrop is by far (> 80 %) dominated by the mud snail Granulolabium bicinctum (Brocchi, 1814), which is a typical inhabitant of intertidal mudflats. A. diluvii is a relatively abundant species in this occurrence and a rather robust shell.


    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).
