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 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!

Hi All, The family and I are heading to Europe next year, and as part of the trip we will be in Frankfurt and will visit the Senckenberg (I went 3 years ago and fully geeked out!). While there we are planning a trip to the Messel Pit. If anyone has any tips to get the most of the visit to the Pit, or any other sites near Frankfurt that are worth visiting then I'd love to hear about them. We will also be going to Innsbruck and Basel (Switzerland), so if anyone knows of any good locations to visit then I'd also love to hear about them. Also, it would probably be good to know about the laws regarding fossils, etc, in these countries - so if anyone knows I'd really appreciate it. Brett.

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

Half a year of polished rudists from St. Bartholomä

"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 -
"Point 25" - What´s behind the red x??
FranzBernhard posted a blog entry in Rudist digging at "Point 25", St. Bartholomä, Styria, Austria (Campanian, Gosau-group)
Now the sandstone slab behind the red x (last photo of the previous entry) has been removed. Can you spot it, just above the pocket knife? Photo taken 09/13/2018. Closer… Closest! There was a large rudist just behind the sandstone slab, lying in a depth of about 40 cm below the surface of the scree slope. Still in situ, only some roots and small stones removed for the photo. Pocket knife is 9 cm long, some tapering of the rudist is clearly visible. Such a nice surprise is very rare, normally the rudists are quite dirty there and you can only recognize a few rips or the typical conical or cylindrical outline. Rudist removed from the scree and photo taken of the uncleaned traverse fracture at the left end in the photo above. The apical view clearly shows two pillars (P1, P2) and a very thick shell, it´s a Hippurites nabresinensis. Photo taken 09/13/2018. Next entry: "Point 25" - Surprise at home! -
Introduction to "Point 25"
FranzBernhard posted a blog entry in Rudist digging at "Point 25", St. Bartholomä, Styria, Austria (Campanian, Gosau-group)
For some general information, including some maps, about the Campanian St. Bartholomä-formation in Styria, Austria see: http://www.thefossilforum.com/index.php?/topic/86433-rudist-hunting-in-st-bartholomä-styria-austria-13072018/ The rudist-bearing St. Bartholomä-formation covers an area of about 3km2. Within this area, there are a few sweet spots, where rudist can be found with some confidence: one of the creeks west of Kalchberg; a pile of rocks west of Kalchberg, collected during centuries from the nearby fields; a small, weathered outcrop along a narrow forest road, also west of Kalchberg; or simply an accumulation of fossiliferous limestone with some rudists in a steep forest east of Kalchberg. But the sweetest spots of all, supplying a continuous flow of rudists, is a scree slope in a small quarry east of Kalchberg - called "Point 25" in my own documentation. The scree slope is located below an outcrop of „Knödelbrekzie“, which is a grain-supported, coarse conglomerate to breccia, exclusive composed of fossiliferous limestone clasts with the occasional rudist, as can be seen in this photo, taken 07/16/2017. The rudist is the cracked, horizontal cylinder-like object in the middle of the photo: The next photo is a frontal view of a part of the quarry. It was operated about 100 years ago for hydraulic marl and is heavily overgrown, in other words, its very dark there and the photos are so-so (as usual). „K“ denotes the exposure of the „Knödelbrekzie“, which was shown in the photo above; below you can see beds of fine grained calcareous sandstone. The „U“ denotes the entry to the underground workings, the entry is largely filled with debris from above. Below the „U“ is the scree slope, consisting of clasts of fossiliferous limestone, sandstone and marl. At the bottom is the „deep hole“, scale bar is 1 m, the red x will appear again. Photo taken 09/13/2018. Lateral view of the quarry. Out of operation since 100 years? It doesn´t seem so. I visited this spot for the first time at 07/16/2017 and two rudists were found instantaneously in the scree (beside the one in the outcrop itself). In October 2017, I decided to examine the material of the scree slope systematically. I began with the nearly horizontal left side and progressed to the steeper right side. Fossiliferous limestone (center left) and marl, sandstone, soil, organic material etc. (at the left edge) were dumped separately. Part of the „deep hole“ is visible in the right corner (note the big sandstone slab in the lower right corner, this slab is also visible in the photo above). I collected and dug at this site from October 2017 until 09/13/2018 about 34 times, each time for about 2 hours. Photo taken 09/13/2018. The „deep hole“. At 09/13/2018, it was about 1.8 x 1.8 x 1.6 m large and something like a quarry in the quarry. Note the red x on the sandstone slab… Photo taken 09/13/2018, scale bar is 1 m. Next entry: "Point 25" - What´s behind the red x?? -
Second photo: About 50 individuals of the snail Vitta picta in different states of weathering, but most of them are still glossy and show their color patterns. The gloss is natural, no coating or something else applied, only washed. The color pattern is strongly variable between individuals. Note that also the outline is quite variable, which is typical for this species. Field of view is 40 mm, largest gastropod is about 6 mm high, so this snails are really small. This is a "multi-genus-species" and was/is assigned also to the following genera: Theodoxus, Agapilia, Clithon, Nerita, Neritina. According to Fossilworks, this species was an epifaunal omnivore-grazer and went extinct 12.7 million years ago. First photo is perhaps the largest and one of the best preserved gastropods of this lot in two views. Height is about 6 mm. It is not perfectly preserved; some parts of the outer shell layer, and hence the color pattern, is missing in the right view. Some parts of the shell along the aperture on the right side are also missing. Outline is quite typical, somewhere in the middle between nearly globular and somewhat cylindrical with a constriction in the middle. Exact locality is Höllerkogel-21 in my own documentation. This relatively large outcrop contains predominately the mud snail, Granulolabium bicinctum, and V. picta. Unfortunatelly, most of the shells are strongly weathered or even completely dissolved. Höllerkogel-21 is about 5 m stratigraphically higher then Höllerkogel-18 and located just upslope of Höllerkogel-18. 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). x

Stratigraphic fossil-rock column (partial) of Styria, Austria (Eastern Alps)
FranzBernhard posted a topic in Geology
Over the last few years, I have made some rectangular polished slabs of fossiliferous rocks from Styria, Austria (Eastern Alps). It occurred to me, that I could try to arrange them in a somewhat stratigraphic order, spanning nearly exactly 400 million years. Numbering is from lower left to upper right, but I think, at least some of the fossils within these rocks can be recognized . I have posted also a map with the approximate locations of these rocks. Palaeozoic of Graz: 1: Orthocerates in dolomite, uppermost Silurian, Kötschberg-formation 2: Crinoid limestone, lower Devonian, Parmasegg-formation 3: Rugose coral and others in limestone, Eifelium, middle Devonian, Plabutsch-formation 4: Tabulate coral Favosites styriacus, Eifelium, middle Devonian, Plabutsch-formation Northern Calcareous Alps: 5: Hallstatt limestone with small ammonoids, upper Triassic 6: Hallstat limestone consisting of monotid bivalve shells (lumachelle), upper Triassic 7: Dachstein coral limestone, Rhaetian, upper Triassic 8: Crinoid limestone (Hierlatzkalk), lower Jurassic Upper Cretaceous Gosau group sorrowfully missing! Neogene basins: 9: Lumachelle consisting of Congeria bivalve shells, Miocene 9: Montastrea? coral colony, Miocene Enjoy! Franz Bernhard

Mysterious fossils from Campanian St. Bartholomä-formation, Styria, Austria
FranzBernhard posted a topic in Fossil ID
I have polished a few slabs today and stumbled over a group of mysterious, tiny fossils. They are in a rudist-bearing limestone clast, width of specimen is 85 mm, they are located a little bit from the center of the specimen toward the lower left corner. Age is Campanian. In the slab 3 mm away from this one, there is nothing to see of them. I am counting 5 large ones and possibly 3-4 small ones, arranged in 2 or 3 rows. They consist of a thick-walled bubble with a very conspicious plug projecting towards the center of the bubble. One of them has a very conspicous stem and maybe one of the small bubbles has also a stem. The largest bubble has an outer diameter of about 3 mm. Bubbles and the steem appear to be segmented, each segment seems to consist of a single calcite crystal, somewhat resembling echnoid sceletal material. The more often I look at them, the more I think they are tiny crinoids??... But I am probably totally wrong. I tried to make a higher resolution scan and a photo with my scrapy camera at highest resoulution, but without great success. Sorry, better photos are not available. Suggestions - despite the poor photos - are highly appreciated. Thanks! Franz Bernhard

Hi guys, last week I was on holiday in Austria and had the chance to hunt at the area of Adnet. There you can find fossils in the red "Adneter Schichten" which are lower jurassic deposits. I was there twice for about 4 hours at all and I found some cool stuff! At my first visit I found plenty of ammonites, one nautilus and some bivalves. It was a very rainy day. Here is a picture of the site: And this is the only ammonite I could prepped until now: Its a 5 cm long Phylloceras. A kinda common species there. The prep work is really difficult, because there is no really separation layer between stone and fossil. I didnt prepped the nautilus until now so I can you show a picture of the unprepped example: On my second visit the weather was very good (maybe even too hot ). Because of that and because of the enormous luck I had I found some shark teeth I didnt really expect to find one although I had already saw some teeth from there on the internet. But I didnt found one I found many Here are the 4 nicest ones until now: The first one is very fragile and 1 cm long: The second shark tooth is about 2 cm long and I like the combination with a crinoid stem: Then this one is about 1.2 cm long and seems to be only a fragment. But I still like it And last but not least the find of the day: A 2.6 cm long shark tooth!! I will try to take better pictures of last and biggest shark tooth after cutting the stone a bit smaller. At the moment the tooth is on a huge stone! The prep work on the shark teeth was also very hard because the teeth are very fragile and the stone is very hard. I prepped it with different needles and with my air scribe I am very pleased with those finds I assume that all shark teeth are Sphenodus shark teeth. Thanks for watching! Hope you enjoyed

Coral (2) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, here is the next (second) coral from the Campanian of St. Bartholomä, Styria, Austria. Not much was visible at the outside (I did not even notice it as coral colony!), but on sectioning, the specimen reveald its beauty. Unfortunately, he contrast is rather low. The two polished sections are about 35 mm apart, the first seems to be near the surface of the colony (with a Lithophaga?). The closest match I can find in Baron-Szabo (2014) is Barysmilia irregularis (Reuss, 1854). Three polished surfaces from this work are attached, scale bars are 5.5, 9.5 and 11 mm, respectively. They are all from the upper Santonian of Neffgraben, Gosau, Austria. Thank you very much for looking and for your help! Franz Bernhard

Rudist hunting in St. Bartholomä, Styria, Austria - 13/07/2018
FranzBernhard posted a topic in Fossil Hunting Trips
Heavy rains in Styria, Austria, have overturned many creek beds. So this is a good time for fossil hunting, e.g. for rudists in St. Bartholomä: View of the hunting area from Pleschkogel mountain (1063 m) toward St. Bartholomä with Kreuzegg and Kalchberg, distance about 8 km. Note the conspicuous church of St. Bartholomä, just below Kreuzegg. View is nearly southward, in the far background the Pohorje mountains in Slovenia. Photo taken 07/07/2018.

Coral (3) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, and here is the next (third) coral from the Campanian of St. Bartholomä, Styria, Austria. First photo: Its the largest specimen I have found so fas. The colony is about 20 cm high and is weighing ca. 4.2 kg. Not much to see, photo just for reference. The grey x indicates the location of the second photo. Second photo: On some parts of the colony, individual corallites are clearly visible. Natural surface, nothing done to it. I have also cut off a piece to make a polished slab. Just about 13 mm below the surface of the colony, the coralites are mostly recrystallized (thats a usual case) Third photo: So I have slightly ground and polished the surface of the cut-off piece, with a somewhat better result, showing a few nice corallites. But I am at a loss with this one, I am recognizing the prominent and thick costae, which let me to the consclusion that it could be belong to Nefocoenia/Neocoenia/Placocoenia/Neocoeniopsis (according to the papers of Baron-Szabo (2003, 2014)). But I can not go any further... Any help is gratefully acknowledged! Thank you! Franz Bernhard

Coral (4) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
...and the fourth (and hopefully last for some time) coral question from the Campanian of St. Bartholomä, Styria, Austria. In this thread I present two different specimens, which I think belong to the same genus: Cycloria or Orbignygyra (according to the papers of Baron-Szabo, 2003, 2014). They are maeandroid, colonial corals. In this first post, two polished slabs of the same specimen are presented. They are about 2 mm apart. The corallites are not very well preserved, but in some spots, some detail is discernible. The "better", less recrystallized side is intergrown with the usual fossiliferous limestone (which contains another small coral colony...).
