    Carrier shell Xenophora deshayesi. This gastropod was a shell collector, having one of his collected items still attached (an olive snail, Olivella clavula (Lamarck, 1810)). The locations of the other shells or shell fragments are still visible. The specimen was found in two pieces and then glued back together


    Shell collector? A friend found another one in this outcrop that collected only small quartz pebbles - obviously a mineral collector!


    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; it is far from exhausted. Most of the fossils are characterized by a partial limonitic staining and usually very good preservation. The species X. deshayesi is not common there, but fragments are not very rare either.

    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).

    Indeed… I supose Xenophora spp. will collect it for a long time.


    Your Miocene Mollusca collection is very interesting. Carlos Ribeiro (1813-1882), member of

    the “Comissão Geológica do Reino”, made a scientific voyage to

    several European countries in 1858. In Vienna he contacted with Hörnes e Suess (he will work on portuguse brachiopoda later) among other.  Hörnes give us a Mollusca collection from Vienna Basin to our Portuguese Geological Survey.


    All of best,

    I love the little olive shell attached to the Xenophora! What an interesting specimen!
