  1. Too lazy to translate it myself, I just put the finished pdf through the google translator : Fossilien_2023_21052023_E.pdf Some, but not all, formating is lost, though. And its just one page of text besides three pages of pics. No worries about the detailed site map, as we already know, nobody cares about rudists . Here is the link to the original, German version, for our German speaking members : Fossilien_2023_21052023 (pdf, 3.4 MB, personal homepage) Here are the original pics: Have fun ! Franz Bernhard
  2. Hello, again a day-off with hiking, mushrooms and some fossils . Its the same area as about 3 months ago, Upper Cretaceous Kainach Gosau, Afling-formation: A field day with blueberries, some mushrooms and - fossils! - Fossil Hunting Trips - The Fossil Forum (With geological map) Same hike, same fossil zone, but different mushrooms. Because now its time for Boletus edulis! Catch the Boletus! First an easy one: Second not so easy: Total yield of the day: The last four weeks, each Sunday or Saturday, I not only carried home some fossils, but also a good amount of Boletus, a total of about 30 in 4 trips. Note: These trips are not specifically designed for mushroom hunting. Just hiking, prospecting and fossiling at known sites. I just stumble over them, more or less, mostly on or near older tractor trails, as can be seen in the pics above. Can´t get enough of the lovely landscape. The area is about 900 m asl, the mountains in the background are about 2000 m asl. Fossils? Of course! Did a little detailed prospecting in the forest above the fossil outcrops at the forest road below and found this Vaccinites. Incomplete, but quite educative: As found: "Good" side: From above, with two pillars pillars, not good pic: Already very happy with this find, I scratched a little bit with a screwdriver at site 63 (see link above) and found a few more fossils (Trochactaeon). Time was ripe to leave, during walking on the forest road about 100 meters away from sites 63 and 64, I found a small Vaccinites in the driveway. Looked at the cut slope of the road - another one. And a big Plagioptychus nearby. Nearly as found: Best of all, I walked by this spot already at least a dozen times... Summing up, another nice day out with hiking, Boletus and fossils! Franz Bernhard
  3. Hello, sure I can not beat the lovely pics, scenery and fossils posted recently by @RuMert, but I also had a nice fossil encounter two days ago (10/02/2021). After prospecting for Pb-Zn-Ba with friends from Lower Austria in the area of Peggau, I decided to visit Römaskogel in Kainach again (just 20 km away), especially to take home a big rudist specimen still waiting there. Arriving there, I decided to check out the surroundings of two recently (some weeks ago) found Vaccinites (quite a distance away from the already known occurrences), on the way to that specimen. Just 50 m away from the car, still far above of the two earlier found specimens, I encountered the first rudist, freely lying on the forest floor. And the next near it, and the next and so on. In total, about 20 specimens were just lying around in the forest in an area of a few 100 m2. And I did not search hard, because most time I tried to find the exposure with these rudists. A step ledge was promising, showing some overgrown exposures of conglomerate. Well, at the northern edge of this ledge, I really found an "outcrop" with rudists, but it could also be a block. I don´t know yet. Anyways, further detailed prospecting is urgently needed ("The Never Ending Story" ). This is the first rudist site in the northern Kainach Gosau with scattered and freely visible rudists not related to forest road construction. The fossil site shown here belongs to the "Upper Rudist Zone" with conglomeratic host rock of the lower Afling-formation (upper Santonian - lower Campanian). All rudists found so far are Vaccinites sp. Map showing fossiliferous zones of the northern Kainach Gosau. The site presented here is the northeastern extension of the dark blue "Hangende Rudisten-Zone". First rudist encounter of that day, near the home of a badger. The pen has a total length of 13.7 cm, the red part is 3.9 cm long, and all rudists are photographed in-situ, unless mentioned otherwise: Just a meter or so away, the second rudist near a root (pen!): And the next one, a slender, nearly complete one, some shell is missing, though: And the next one nearby, not very obvious (below the red x), but its a short fragment of a Vaccinites: The next one near a big root. Not well visible on the larger pics, but this was a real surprise, see last pic... Ups, turned out to be a large, nearly complete Vaccinites, nearly 20 cm long. The opposite site is a little bit crushed, but that´s ok, nobody is perfect . And so on and so on... This is the supposed outcrop as found (below the red x), very tiny (as everything in Austria ), and a loose rudist specimen near the pen. You can imagine something like a ledge in that area, if you like : "Outcrop" a little bit cleaned: Loose specimen in detail, a fragment of a big Vaccinites: "Outcrop" in detail: "Outcrop" after excavation. Its a pseudocolony of several Vaccinites, already broken into 4 pieces. Haven´t explored the "scenery" behind that pieces yet. Maybe its part of a larger outcrop, probably not: And last, something geological. Here and there you can find quite big boulders mostly made of fossil-free limestone or dolostone in the northern Kainach Gosau. This is a dolostone boulder of at least one cubic meter in size. Its a giant clast within the conglomerates and probably of paleozoic age: Hope you enjoyed a litte bit, thanks for looking. I am still very surprised and somewhat excited by that find, the first area with naturally free lying rudists of the northern Kainach Gosau. You never know whats behind the next tree, even in such a supposed fossil-poor area like the Kainach Gosau. Prospecting is everything ! Franz Bernhard
  4. Hello, I would like to ask if someone is able and would like to look up the derivation/meaning of the name of the rudist genus "Vaccinites". It was introduced by Fischer (1887) in this work: It could mean something like "cow horn" (Vacca = cow). But I am not sure and can not find something really definitive with google. Thank you very much for your help! Franz Bernhard
  5. Hello, several weeks ago, I presented a rudist recovery "operation" from the Afling-formation of the Gosau-group of Kainach (Upper Cretaceous): Well, the same day I have discovered the rudist zone featured above, I have also discovered a rudist zone about 100-200 m stratigraphically deeper. It is confined to an about 1 m thick, very dark limestone bed rich in various rudist and echinoid remains. The limestone belongs to the Geistthal-formation, considering the limestone is still located within the sequence with some red clastic rocks, suggesting strong terrestrial influence in some layers. The limestone can be traced for at least 500 m along strike; at the footwall, it develops gradually from a conglomerate, in the hangingwall it is sharply overlain by fine-grained sandstone to siltstone. Here is a schematic map of the area, including also the Trochactaeon-bearing zone. In this post, I am dealing here with the "Liegende Rudisten-Zone". 59 = Geistthal-formation; 54 = Afling-formation, squares are 2x2 km. The fossils stick firmly to the limestone. But there are some impure zones (sandy-silty) within the limestone, where, with the help of some weathering, some fossils largely free of matrix can be found. Two zones of this kind are known at the moment, a natural outcrop in the forest and an outcrop at a forest road, which will be presented here. Approaching the outcrop (well, that pic was taken after the dig...): The outcrop was completely overgrown at the beginning, and this was the third day of working at this outcrop. You can see the worked area and the area prepared for today. The red x are markers placed above wooden marker sticks and about 1 m apart from each other. The soft zone between the hard limestone beds is visible. Sorry for the rather poor pics, my scrappy camera had a hard time dealing with that kind of lighting (clear sky and full shadow). Detail of the area to be worked today, still with vegetation: Vegetation cleared, first rudist found, a fragmentary Vaccinites, below the left red x. The pen is 13.7 cm long. Work in progress, "two" Vaccinites discovered. Only after some time I recognized, that this is a bouquet: Work practically finished, another Vaccinites discovered (4963). Turned out to be one of the nicest so far: Beside these Vaccinites, a few Plagioptychus aguilloni were also found in that area. But what to do with the rudist bouquet? Leaving in the outcrop or recover? I decided to recover, because it was already a little bit loose and already broken in several parts. And a one of a kind find until now. Here is the recovery, P.a. denotes a Plagioptychus aguilloni, numbers indicate individual Vaccinites specimens: The recovery ended in 8 fragments. I numbered them to help reassembling them together. This bouquet appears to be in live position, but this can also be by pure chance. Maybe closer examination with give some hints. That´s the outcrops after the work of this day, with the position of the specimens featured above indicated and before their recovery: If you are interested in the other days at this outcrop, have a look at this: 05/22/2021 (link to my homepage, in German, pdf, ca. 2.9 MB) 05/30/2021 (link to my homepage, in German, pdf, ca. 5.8 MB) From this few meters of outcrop, I have recovered ca. 10-15 Vaccinites, 5-10 Plagioptychus aguilloni and several radiolitid rudist until now. A great surprise was one large Trochactaeon snail intermixed with all the rudists (see link to 05/30/2021 above). I don´t take all fossils with me, about half of them I am leaving at the outcrop, so only approximate numbers. In the pavement of the forest road below the outcrop, I have also dug out about 15 Vaccinites specimens. Then there is the outcrop within the forest, which yielded also at least a dozen Vaccinites, still with a lot of potential. And all the other outcrops of the rudists limestone that I have not checked out in detail yet for loose rudists. Also still a lot of potential there and still a lot to do.... Hope, you enjoyed !

  6. Hello! Having discovered some new rudist occurrences in the lower part of the upper Santonian - lower Campanian clastic-marine Afling-formation at Römaskogel hill near Kainach, western Styria, Austria, about 6 weeks ago. Here I would like to present a very specific visit to one of these sites at 05/15/2021. It was aimed to recover some more parts of already known rudists from the outcrop at site #30. Here we go! Approaching Römaskogel, the hill in the middle. Its 1006 m high, the snowy mountain in the background is the Gleinalpe mountain, nearly 2000 m high: Already near Römaskogel hill, again the hill in the middle. These meadows are much steeper than they appear in the pic: Location of the rudist outcrop along a forest road: Rudist outcrop, scale is 1x1 m. The rudist-bearing zone is about 80 cm thick and tips gently towards south to southeast. Individual conglomeratic rudist-bearing beds are separated by layers of siltstone. The whole extensions of the rudist-bearing zone seems to be at least about 300 m, with about 5 outcrops and indications known until now. This is the best outcrop discovered so far. Right part of the rudist outcrop. At the lower end of the scale, the next pic. The digging spot of this day is to the left of the pen: Rudists ("Vaccinites Rö1") in conglomerate in the outcrop, diameter is about 5 cm: The digging site as left at 05/06/2021 and found again a week later at 05/15/2021. I had already recovered two parts of #4901 and one part of #4910. The soft siltstone in the footwall of the rudist bed clearly facilitated the recovery of the remaining parts from the relatively hard conglomerate. The pen is 13.7 cm long: Intermediate stage of recovery. The rudists are orientated parallel to the bedding plane. They are flattened, the two big ones lying with the flat side on the bedding plane. The smaller one is orientated "on edge" to the bedding plane: Here is a primitive, highly schematic and out-of-scale sketch of the situation. #4901 and #4910 are also oriented antiparallel: Dig site after removing all the rudists. #4901 yielded two more fragment (total of 4), with the very last tip still remaining in the outcrop. #4910 yielded also two more fragments (total of 3, completely recovered). #4914 recovered in two fragments: Right part of the rudist outcrop after recovery of these three rudists. Notice the difference to the start of the recovery : Here is the complete specimen #4910. It consists of 4 fragments, that were already naturally broken. Uppermost part was found 05/01/2021, next part was found 05/08/2021, lower most parts are from 05/15/2021. The rudist is strongly flattened (about 1:2), as most of the specimens from this bed, and about 21 cm long. I don´t know the species yet, working name is "Vaccinites Rö2". (Remember, nothing was known in that area until about 6 weeks ago.) The shell has a flame-like structure, which can be nicely seen in the naturally weathered transverse section. These structure corresponds to the fine longitudinal striation of the shell. Otherwise, the rudist is smooth without any ribs. In the cross section, the P-pillars are barely visible to the right, the L-pillar is not visible: Not much time was put into this recovery, most of the day was spent prospecting an area nearby. "Discovered" a freshly widened forest road (actually as wide as a good highway!) which perfectly exposes the mostly alluvial and reddish Geistthal-formation and the following clastic-marine Afling-formation for some 100 m thickness. Not much was found, but its a very, very impressive section. Here is my prospecting area (Römaskogel is in the lower left corner) and route (in blue) of that day. Red R indicate the last (highest) reddish beds: Still a lot to walk and observe during my next trip, especially to the east of the already explored area.... You never know what you will find. For example, #45 and #46 are small Trochactaeon indications. But these will be followed up next spring, when the green has gone again. Or not at all . I only made one pic during prospecting, that of a thin (1-2 cm) seam of subbituminous coal withing silt-claystone, located between conglomerate beds (#47). Such occurrences are well-known in that area: So, that was quite a typical day in the field for me: Some collecting at known sites, but more prospecting for new sites! Thanks for looking and your interest! Franz Bernhard
  7. Hello, this time, I will start with the end result : I am quite satisfied with the result ! The pillars are nicely preserved and the rudist is filled with sparry, white to orange calcite and contains some voids coated with tiny calcite crystals. The greenish batches consist also of calcite and are also well polished, but are finer grained and contain additionally some small quartz grains. These fillings may be related to the second filling event during redeposition of the rudists in this formation. For more info about that, see here: Some Rudists from St. Bartholomä The right section contains also a blob of fossiliferous limestone. More about the locally heavily bored shell - see below . Before I got this nice result, there was a decision - to cut or not to cut : It is a conical specimen with some ribs preserved and a large, interesting, vertical groove. A large blob of limestone is sitting at the top end of the rudist, but one pillar was also already visible there. Mostly due to the ugly limestone blob, I decided to cut the specimen near the end of the visible shell. The top part (AN4240) does not contain much shell, the section about 6 mm lower (AN4239) does. The vertical groove is a simple inflection of the shell. No clue, what caused it, no remains of any other shell are visible. But it may have been some kind of an obstacle there. The specimen was found in a steep, wooded area east of Kalchberg, at the lower end of an old vertical ditch, possibly a prospect for water. Some pieces of fossiliferous limestone were lying around, somewhat exposed by heavy rains. I dug with bare hands in the soil, and nearly immediately recovered the specimen above from the "rat hole" to the right of the pocket knife (first row): (At the upper left corner of the upper left pic, a rudist is sticking between tree roots. This rudist was already featured here: Rudist hunting (3) in St. Bartholomä) Yesterday, I visited this spot again and pulled out several more pieces of limestone and sandstone from this "rat hole" (about 200 pieces), again only with bare hands (second row). No large Vaccinites was found this time, put a few smaller specimens (third row): upper left: small Vaccinites specimen; upper right: small pseudocolony of Hippurites colliciatus; lower left: Hippurites nabresinensis; lower right: fragment of Vaccinites vesiculosus. Ok, not much to see on this sucking pics, so I will stop now . Thanks for looking, maybe you have at least enjoyed the polished specimen . Happy hunting! Franz Bernhard

    Vaccinites alpinus (Douvillé, 1897)

    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).

    Vaccinites vesiculosus (Woodward, 1855)

    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).
