I did it again!! Fossil hunting in the Northern Kainach Gosau, Styria, Austria (Upper Cretaceous)
FranzBernhard posted a topic in Fossil Hunting Trips
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 !

Another day with mushrooms and fossils in the Kainach Gosau, Styria, Austria
FranzBernhard posted a topic in Fossil Hunting Trips
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!

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 !

Trochactaeon snails - Kainach, Styria, Austria - 10/10/2020
FranzBernhard posted a topic in Fossil Hunting Trips
Could not resist collecting some more Trochactaeon snails at Breitenbach-11 in Kainach, Styria, Austria last Saturday (10/10/2020). Especially the upper T-bed contains rather well preserved (for the formation, of course ) snails. But always the right amount of weathering is needed (not too much, leads to disintegration of snails; not to less, they will adhere firmly to the rock). Still some potential there. Worked only with a screwdriver, needed only a few very gentle hammer taps. No prepping, just a short brush with a soft tooth brush. For more info about the area, have a look at my previous post: Trochactaeon - Gosau of Kainach, Styria, Austria - Summary Franz Bernhard- 1 reply
