From time to time, I would like to post specimens from the Campanian St. Bartholomä-formation in Styria, Austria, in this thread. For the first specimen, I was motivated by this thread: http://www.thefossilforum.com/index.php?/topic/91459-is-this-a-rudist-fossil/ So the first specimen is a fragment of a large Vaccinites alpinus, with only two pillars - and not much else.

Visiting some of the oldest fossils of Styria, Austria (Silurian orthocerids and brachiopods)
FranzBernhard posted a topic in Fossil Hunting Trips
Very small outcrops northwest of Graz are perhaps the richest site of Silurian fossils in Styria. There may be other sites with somewhat older macrofossils in Styria, but not as rich. The outcrops are part of the Palaeozoic of Graz, a thrust sheet within the Eastern Alps, composed or Silurian to Pennsylvanian sediments. It consists of three separate nappes, the outcrop and fossils presented here belong to the Eggenfeld-member of the Kötschberg-formation within the Rannach nappe. Geological map of Styria with the Palaeozoic of Graz situated north of Graz. The red X is the location of the fossil site. Geological and structural map of the Palaeozoic of Graz. Note that the colors of the Rannach facies and Hochlantsch facies have been accidentally interchanged, the red X is the location of the fossil site. From Gasser et al. (2009). Stratigraphy and facies distribution of the Palaeozoic of Graz. Kötschberg-formation is Nr. 10 (red X), thicknesses of formations are not to scale. From Gasser et al. (2009). The age of the Eggenfeld-member is, based on conodont data, upper Silurian (Ludlow, Pridoli) to lowermost Devonian (Lochkovian). What´s special about this site is the abundance of orthocerids in some only a few dm thick layers of grey to brown dolomite and dolomitic limestone that are intercalated with tuffitic rocks. And also somewhat special is the number of papers dealing with these very small and poor outcrops. The occurrence of orthocerids is known since the 1950ies, a good up-to-date (2010) summary is this paper, it mentions 16(!) nautiloid taxa, most of them orthocerids. Its in English and includes pics of fossils and a stratigraphic section: GPZ_Eggenfeld_Histon_2010.pdf These are the seven nautiloid genera figured in this paper, no species assignment was made.

Some Fossils from the Plabutsch-Formation of the Palaeozoic of Graz, Styria, Austria (Devonian – Eifelian)
FranzBernhard posted a topic in Member Collections
Supplementing the post in “Fossil Hunting Trips” about the Devonian Plabutsch-formation in Styria, Austria (with some background info): http://www.thefossilforum.com/index.php?/topic/90431-some-fossil-hunting-in-the-plabutsch-formation-of-the-palaeozoic-of-graz-styria-austria-devonian-–-eifelian/ I would like to post some more fossil specimens in this thread. More specimens will follow from time to time (hopefully). The first two specimens contain abundant branches of the tabulate coral Striatopora? suessi. Field pics of these specimens are already posted in the hunting trip, but here you can see also their side views, showing the alingment of the individual coral branches. (I don´t know why pics don´t look good here, but if you are zooming in, they are ok).

Some Fossil Hunting in the Plabutsch-Formation of the Palaeozoic of Graz, Styria, Austria (Devonian – Eifelian)
FranzBernhard posted a topic in Fossil Hunting Trips
As there are some polished fossil-rock specimens from this formation in the Christmas auction, I would like to present some background info with (mostly) some field photographs, so I have put this in “Fossil Hunting Trips”. The Palaeozoic of Graz is a thrust sheet within the Eastern Alps, composed of Silurian to Pennsylvanian sediments. It consists of three separate nappes, the most fossiliferous formation is the Plabutsch-formation within the Rannach nappe. This Devonian formation is of Eifelian age (ca. 395 Ma), about 100 m thick and mostly made up of a very dark, gray-blueish to black, fine-grained, thickly bedded limestone. Superficially, it weathers to a medium to light grey color. Geological map of Styria with the Palaeozoic of Graz situated north of Graz. Stratigraphic column of the Rannach nappe of the Palaeozoic of Graz, Plabutsch-formation is Nr. 4. From Hubmann & Gross, 2015. Thicknesses of formations are not to scale! The Plabutsch-formation crops out at various places to the west and north of Graz and more than 100 fossil sites are known within this formation. The most abundant fossils are corals, brachiopods, stromatoporids and crinoid fragments. Other fossils like gastropods, bivalves or trilo-bits are very rare. In a paper from 1975, about 50 coral species are listed, but less than 10 are abundant: Tabulata: Favosites styriacus Penecke, 1894 Pachycanalicula barrandei (Penecke, 1887) Thamnopora boloniensis (Gosselet, 1877) Thamnopora reticulata (Blainville, 1830) Striatiopora? suessi Penecke, 1894 Rugosa: Thamnophyllum stachei Penecke, 1894 Zelophyllia cornuvaccinum (Penecke, 1894) Do you feel that there is something strange with this list? Yes, it is! Most species have their type locality within this formation and were first described by Penecke, except T. boloniensis (T. reticulata was also erected by Penecke as Pachypora orthostachys and later synonymized with an earlier described species). In my opinion, this does not reflect a high degree of endemism, but an urgent need for revision… The most abundant fossil is Favosites styriacus, which can form massive colonies up to 0.5 m in size. Here is an example from Hohe Rannach Mt. (1018 m) north of Graz, photo 05/26/2018, Col-Nr. 4093, length of pocket knife is 9 cm: As most fossils in this formation, it was found in scree and float in a wooded area. Nr. 4093 is waiting near the pocket knife toward the lower right corner… Another Favosites styriacus, north of Fürstenstand Mt. (754 m), northwest of Graz, photo 10/30/2015, not in collection. Tabulae are very well visible, weathering is usually your friend there!

Hello, I would like to ask, if somebody has seen such rudist traverse sections somewhere else (first und second post). Compared to the other four, abundant species (third post, for comparison), these three types are rare in the St. Bartholomä-formation and these are all that I have. Both apical and adapical views of this rare ones are shown, if possible. Some of them I have already posted on TFF, but here they are all together. They are all from the Campian St. Bartholomä-formation in Styria, Austria (Gosau-group, Eastern Alps). The specimens labeled Vaccinites cf. sulcatus come very close to them I have seen in the literature. The "names" Hippurites cf. nabresinensis and Hippurites cf. colliciatus are not much more than tags, I have not seen something similar in the literature yet. Many thanks for your help and oppinions!

Coral (5) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, here I am again with a recently (10/14/2018) found coral colony from the Campanian St. Bartholomä-formation in Styria, Austria (Gosau-group). Its very poorly preserved and I have only very little hopes that it is possible to assign a genus to it. I don´t think its an Actinastrea, it seems more like a Barysmilia (according to Baron-Szabo, 2014), but I am really clueless. First pic is a polished part of the specimen. Preservation is very poor. Second pic is the "upper" surface, its strongly worn, only the position of the corallites can be seen, with some occasional septa. The polished area is located at the bottom. Third pic is an oblique side view. The specimen measures about 10 cm in its longest dimension. Worn-down corallites can be found all around the specimen. Thank you very much for your patience, help and opinions! Franz Bernhard

Rudist hunting (3) in St. Bartholomä, Styria, Austria - 10/23/2018
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, another surface rudist hunt in St. Bartholomä, Styria, Austria (Campanian St. Bartholomä-formation, Gosau-group). This time not in a creek, just wandering in the forest. Two larger rudists were found, lying on the surface. One for me, with partialy preserved upper valve:

Half a year of polished rudists from St. Bartholomä
FranzBernhard posted a topic in Member Collections
Hello, just to show off some polished rudists from the Campanian St. Bartholomä-formation, Styria, Austria, collected from March 2018 to September 2018. https://franzbernhard.lima-city.de/Radiolitidae_04bis09_2018.html https://franzbernhard.lima-city.de/Hippurites_04bis09_2018.html https://franzbernhard.lima-city.de/Vaccinites_04bis09_2018.html Enjoy!

"Point 25" - Summing up
FranzBernhard posted a blog entry in Rudist digging at "Point 25", St. Bartholomä, Styria, Austria (Campanian, Gosau-group)
Here are the numbers I promised : From 07/16/2017 to 09/13/2018, about 140 hippuridit rudist specimens were found in the scree slope of "Point 25", the sweetest of all spots in St. Bartholomä. The species distribution is (approximate numbers, with examples): Hippurites colliciatus: 80 (with 140 individuals – many pseudocolonies!) - F, G, H, J Hippurites nabresinensis: 10 - I and possibly K Vaccinites vesiculosus: 25 - A, B Vaccinites alpinus: 10 - C Vaccinites cf. sulcatus: 5 - D, E Vaccinites sp.: 10 (no pillars visible, but to nice to be cut, or partial specimens) Polished traverse sections of hippuritid rudists found at "Point 25" from 01/20/2018 to 03/23/2018: Only hippuritids in this spot? No, during the same period, about 200 radiolitid rudists were also found, giving a total of about 340 rudist specimens from this spot. Thats about 70% of all rudists found in the St. Bartholomä-formation during my hunting and digging trips from 05/07/2017 to 09/13/2018. Ah, and about 10 coral colonies ware also found at "Point 25"... It is difficult to estimate how many rudists are still waiting in the scree there. Judging from - the amount of material already removed and dumped (about 3-4 m3), - the distribution of fossiliferous limestone and other rocks in the scree slope (about 1:2, but highly variable), and - considering the amount of „Knödelbrekzie“ that seems to be missing in the outcrop (and now lying in the scree), I will try to make an estimate of 200 to 500 rudists that are still there to be found. Now I am stopping! Thanks for your patience! Franz Bernhard -
"Point 25" - Surprise at home!
FranzBernhard posted a blog entry in Rudist digging at "Point 25", St. Bartholomä, Styria, Austria (Campanian, Gosau-group)
Fine, a very nice rudist - a Hippurites nabresinensis -, one of the longest I have found so far in St. Bartholomä (18 cm). But it came even better! At home, I recognized that I have already seen a quite similar traverse fracture before. Indeed, here it is, with the cleaned traverse fracture of the newly found rudist below. Maximum diameter is about 7.5 cm. The two parts fit together (considering that there are at least 100 years of weathering between them), resulting in the by far tallest rudist found by me in St. Bartholomä up to now, having a total length of about 27 cm. The shorter part was found at 05/20/2018, about 2 m downslope of the second, longer part, in a depth of about 10-20 cm. Note that the longer part has a kink at the upper end. The upper part is also the natural end of this rudist, as some parts of the upper valve are preserved (upper left). I could stop now, but I don´t. Some people may like numbers, so I will present some in the next entry: "Point 25" - Summing up
