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).

Apical view of a polished cross section of the right (lower) valve of Hippurites nabresinensis from the St. Bartholomä-Formation of the Gosau basin of Kainach - St. Bartholomä in western Styria, Austria. This species has no L-pillar, the P1-pillar is at ca. 3:00, the P2-pillar at ca. 5:00. The hump at ca. 8:00 is a growth anomaly. At ca. 11:00 and 1:00, the position of both teeth sockets is visible (a hypothetical L-pillar would be between them, see the specimen of H. colliciatus), at ca. 2:00 the position of the posterior muscle. At the upper left, it is intergrown with the fragment of another individual of the same (?) species. For specimens like this, the name H. heritschi was also in use. The specimen is from a large mound of stones, which were removed from the fields during many, many decades. This mound located in the southwerstern part of Kalchberg, southwest of St. Bartholomä (Point 36 in my own documentation).

Apical view of a polished cross section of a pseudocolonie of three indivuals of Hippurites colliciatus from the St. Bartholomä-Formation of the Gosau basin of Kainach - St. Bartholomä in western Styria, Austria. The pillars (L, P1, P2) are indicated, the L-Piller of this species is only a small hump. Left and right of L, the position of both teeth sockets is visible, left of P1 also the position of the posterior muscle. For specimens like this, the name H. exaratus was also in use. The specimen is from a small scree in a small, abandoned marl quarry, located in the eastern part of Kalchberg, southwest of St. Bartholomä (Point 25 in my own documentation).

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.

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).

Apical view of a polished cross section of the right (lower) valve of Vaccinites alpinus from the St. Bartholomä Formation of the Gosau basin of Kainach - St. Bartholomä in western Styria, Austria. Typical are the subparallel pillars, all situated in a small area of the rudist. The shell around the L-piller (left one) is missing in this specimen. For specimens like this, the name Hippurites/Vaccinites cornuvaccinum was in use. Study of specimens with preserved upper valve showed that V. cornuvaccinum is restricted to the Coniacian and V. alpinus to the upper Santonian and Campanian (Steuber & Schlüter, 2012). They can not be distinguished with the lower valve alone, but have different upper valves. Hence, identification is (also) based on stratigraphic information (Steuber, 2001: „This species [V. ultimus] was also figured by Kaumanns (1962) from Kainach (Styria) and erroneously assigned to various species of the group of V. cornuvaccinum.“). By the way, V. ultimus is a junior synonym of V. alpinus... (Steuber, 2003). The specimen is from a small scree in a small, abandoned marl quarry, located in the eastern part of Kalchberg, southwest of St. Bartholomä (Point 25 in my own documentation).

Apical view of a polished cross section of the right (lower) valve of Vaccinites vesiculosus from the St. Bartholomä-Formation of the Gosau basin of Kainach - St. Bartholomä in western Styria, Austria. Typical are the slender L-pillar (at ca. 12:00), the round P1-pillar with a very slender stem (at ca. 2:00) and the spatula-shaped P2-piller, also with very slender steem (at ca. 3:00). For specimens like this, names like Hippurites styriacus und Hippurites carinthiacus were also in use. The specimen is from a small scree in a small, abandoned marl quarry, located in the eastern part of Kalchberg, southwest of St. Bartholomä (Point 25 in my own documentation).

Hippurites from St. Bartholomä, Styria, Austria (Campanium)
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, just to show off some of my finds of Hippurites from August to October 2017 in the Campanian St. Bartholomä-formation of the Gosau basin of Kainach - St. Bartholomä, Styria, Austria. Upper right: 5x Hippurites colliciatus Woodward, 1855 Lower left: 4x Hippurites nabresinensis Futterer, 1893 If you are interested in field photographs etc., see: https://franzbernhard.lima-city.de/SanktBartholomae_Fossilfunde_Hippuritidae_Teil_3.pdf https://franzbernhard.lima-city.de/SanktBartholomae_Fossilfunde_Hippuritidae_Teil_2.pdf (in german) Franz Bernhard

Hello, again I would like to ask for your kind help. I have two sectioned fossils from the Campanian Gosau basin of Kainach, Styria, Austria (St. Bartholomä-Formation). They are accompanied by radiolitid rudists (R), but I don´t think that they are rudists by itself. Could these be some kind of sponges? But I can not see any spicules. Frist specimen is 13.5 cm high, sections are ca. 3 mm apart. Second specimen is 11.5 cm wide, sections are ca. 16 mm apart. There is nothing visible on the wheatered surface, except some Radiolitid fragments. I know this website: http://www.cretaceous.de/ But I have not found anything definitive about sponges of the Austrian Gosau formations. Maybe someone can give me a hint? Thank you very much for your help! Franz Bernhard Specimen 1 Specimen 2

Hello, this time a very mysterious fossil from the Gosau basin of Kainach, Styria, Austria (Campanium). A piece of limestone full of tubes with diameter up to 7 mm. There seem to be a variation of longidutinal ribs on the outside of the tubes. They are associated with one (lowest left) or two Hippuritids. I think these are serpulid worms, maybe genus Pyrgopolon, maybe something near to P. voigti Jäger, 2004. P. regia and P. macropus don´t fit 100%. What do you think? Problem is, I can not find any reference about serpulids from the Austrian gosau basins - ? Thank you very much for your help! Franz Bernhard

Hello! I am currently looking for the rudists of the Upper Cretaceous Gosau basin of Kainach, Styria, Austria, around St. Bartholomae. So far, I have found one determinable specimen. I think, it could be Vaccinites vesiculosus (Woodward 1855). From this area, beside other rudists, Hippurites styriacus Hilber 1902, Hippurites carinthiacus Redlich 1899 and Hippirutes oppeli santoniensis Kühn 1954 are described in the literature, which seem to be all synonyms of V. vesiculosus, according to various sources. The first photo shows the outer surface of the specimen, which is not very distinctive. Height of the specimen is 13 cm, maximum diameter about 7 cm. A saw cut is indicated by a green arrow. The second picture shows the two polished, cut surfaces of the "rock". The diamater of the large rudist is 7 cm, it seems to be intergrown with a Radiolites sp. and there is also a small Hippurites sp. nearby. The third picture is an enlargement of the V. vesiculosus in question. What do you think, could my determination as V. v. be correct? Thank you very much for your help! Franz Bernhard Picture 2
