    Acanthocardia paucicostata with matrix. Note the prominent spines, which can develop into spoons in some specimens. Compare with a recent specimen from WoRMS: http://www.marinespecies.org/aphia.php?p=image&tid=138993&pic=65227

    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. paucicostata is a relatively abundant species in this occurrence.


    The sediments in the area belong "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).
