Hello, I would like to ask for opinions about this 5 mm "tall" gastropod. Its from the Langhian - Miocene (15 Ma old) "Florianer Schichten" of the Styrian Basin in western Styria, Austria (St. Josef, site Fuggaberg-3). Other molluscs at this site are Granulolabium, Terebralia, Anadara, Acanthocardia, tellinid bivalves, oysters, naticids, buccinids etc. Many thanks for your help! Franz Bernhard

Mollusc habitats - Florianer Schichten, Styrian basin, Austria (Langhian)
FranzBernhard posted a topic in Member Collections
I am not sure, where to post this, please feel free to move it to the appropriate topic. I made the schematic drawing of mollusc habitats already more then 2 years ago, now I have pepped it up with shell pics of the most abundant species. All shells are self collected and in my collection, but no scale, no names... The largest pics are the most abundant molluscs in this area, there are only about 5 of them, that are really super-abundant. There is a lot of hidden info in this pic, but is it discernible without any further explanation? Maybe you have at least some fun ! Franz Bernhard

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).

Volute snail Athleta rarispina on matrix. Note the very well preserved borings of an unknown organism. 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. rarispina is moderately 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).

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). Ref: Messner, F. & Bernhard, F.

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.

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).
