Classic Trochactaeon and rudist sites at Waaggraben, Hieflau, Styria, Austria (Gosau-Group, Upper Cretaceous)
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, last Saturday (10/09/2021), I visited again some classic fossil sites at Waagraben, Hieflau, northern Styria, Austria with a friend. These sites are known since around 1850, are probably of Coniacian age and belong to the Gosau-group. First, some maps: Overview with location of Waaggraben in Styria, a geological map from Ampferer, 1935 (1 = rudists; 2 = Trochactaeon; 3 = Conglomerate quarry), topo-map, and DEM. These sites are very well known, so no problem to pinpoint them exactly on maps: On the way. We will meet this guy in the backgrou -
New Rudist Site at Römaskogel, Kainach, Styria, Austria (Gosau-Group of Kainach)
FranzBernhard posted a topic in Fossil Hunting Trips
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 fro- 5 replies

Rudist hunting (5) in St. Bartholomä, Styria, Austria (Gosau-group, Campanian)
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, Another hunting trip for rudists to the Campanian of St. Bartholomä in western Styria, Austria (09/15/2019). I have hunted these heaps of stones, collected from the former nearby fields (now meadows) over centuries, several times before, but there seems to be always something to find. I found six "good" specimens in 2 hours - and that´s exactly my usual yield in this formation . First topo map, geological map, relief map and aerial photograph of "Point 32". No problem to make everything public, nobody is interested in this stuff (well, except me...). Views fr- 12 replies

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 i

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:

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- 1 reply

Fossil snails of the genus Trochactaeon from Kainach near Voitsberg, Styria, Austria (Gosau-Group of Kainach, upper Cretaceous) - Summary of this years prospection Introduction Snails of the extinct genus Trochactaeon (formerly part of the genus Actaeonella) are among the most familiar fossils of the upper Cretaceous Gosau-Group of the Austrian Alps. The rather large size of some species (>10 cm), their intriguing spiral pattern in transverse sections and plenty supply, based on many mass occurrence, make them particularly popular. Some well known occurrences in Austria, di

Hello! I have collected quite many specimens with Trochactaeon snails from April to May 2020. They all come from the Upper Santonian to Lower Campanian upper Geistthal-formation or Lower Afling-formation of the Gosau of Kainach in western Styria. Some of the specimens contain abundant black, wavy, "folded", shell fragments. They seem to grow on the Trochactaeon snails in some places. They resemble small oysters in some ways. Unfortunately, I have not found anything conclusive about their identity. I found a pic in a paper of Kollmann (2014), with some somewhat similar, unidentified b

04/13/2020: End of my lock-down. Visited a locality with oncoids-oncolites in the Santonian - Lower Campanian Geistthal-formation (59) of the Gosau-basin of Kainach. Locality is near Kreuzwirt south of Geistthal and was told to my by a friend, so I will keep it secret. This is a specimen from block 1. Most of block 1 is still there, I removed only about 2 kg (2 specimens) of the about 40 kg heavy block. Only two more blocks of this material were found, despite really good outcrops just nearby (with alternations of conglomerates, sandstones and siltsones). There should

Hello, some local Campanian news again... . First: The rudists from St. Bartholomä, Styria, Austria, made into a local journal (pdf, in German): DieRudistenvonStBartholomae_Mineralog_2019.pdf Second: After this nice find at point 25-North from 09/24/2019: Point 25-North - 09/24/2019 I could not resist collecting this site systematically. 18 hours of work in October and November 2019 resulted in more than 100 fossils, which is a very good yield. For details see: Point 25-North - Four weeks (External site, in German, only a few pics). Th -

Rudist hunting (6) in St. Bartholomä, Styria, Austria
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, today I had another opportunity to fossil hunt in St. Bartholomä. I tidied mostly up my main dig and collecting site in the quarry at Point 25 east of Kalchberg. As expected, I did not find much, only some small so-so specimens (19 specimens in 3 hours, but the majority would be rejects). However, in the same small quarry, a few meters to the north of the main dig site, "Knödelbrekzie" is also exposed (upper part of lower right pic), with some steep scree below. I have found two good rudists in this scree two years ago. Today, I dug again with bare hands in the scree. F- 8 replies

The next "objet d´art" from St. Bartholomä. Or: Rudist hunting (4) in St. Bartholomä
FranzBernhard posted a topic in Fossil Hunting Trips
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 T- 8 replies

Coral (12) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
First of all: The book about the Coniacian-Santonian corals of Rußbach-Gosau, Austria, by Löser et al. (2019) is printed. It can be ordered at: http://www.korallen-kreide.de/index.html Its a must-have for all people interested in fossil corals! And: The abridged English version is also ready for download there! And now to my first application of this important milestone work: During my searching and digging at point 36 west of Kalchberg, St. Bartholomä, Styria, Austria, at 07/04/2019, I found also a piece of limestone with small, regular voids/holes/tubes.

Corals (10 + 11) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
My hunting at point 25 east of Kalchberg at 05/16/2019 did not yield any good rudist. However, two coral colonies were found. Now I have a total of about 20 from this formation. This one is very small, poorly preserved and has a very, very low contrast (already strongly enhanced). It has some similarities to that one, but only remotely: http://www.thefossilforum.com/index.php?/topic/87677-coral-3-from-the-campanian-st-bartholomä-formation-styria-austria-gosau-group-eastern-alps/ Corallites seems to have a diameter of about 1.2 mm.

Together with these two coral colonies http://www.thefossilforum.com/index.php?/topic/96001-corals-10-11-from-the-campanian-st-bartholomä-formation-styria-austria-gosau-group-eastern-alps/ I "discovered" also this specimen during my last visit at point 25, east of Kalchberg, in St. Bartholomä. "Discovered"? - I have found this specimen about a year ago, but did not take it with me - "It´s just a mineral". As I have not found much during my last visit, so I took it with me this time... After cleaning, I saw a somewhat faint wavy lamination - "Ah, some kind of calcite deposit"...

Coral (8+9) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
The next two corals from St. Bartholomä... I collected this specimen nearly a year ago. Thought, it has some kind of borings. But I was a little bit confused, because most of the "borings" or tubes have a regular and tight, axial ornamentation. Polished cross sections revealed not much, but a few corallites (A, B, C). One of the tubes at the margin of the specimen shows some "shell" material with ornamentation on both sides (D). The left side is in contact with younger sediment, the right side with fossiliferous limestone. On the surface of the specimen, no shell material was observed wit- 3 replies

"Fossil ball" - Campanian St. Bartholomä-formation, Gosau group, Eastern Alps
FranzBernhard posted a topic in Fossil ID
This time a really odd ball from St. Bartholomä, Styria, Austria (West of Kalchberg, point 36). Collected 04/09/2019. Campanian St. Bartholomä-formation, Gosau group, Eastern Alps. The specimen was very dirty, thought it is just a round and smooth limestone piece, but haven´t found such a smooth piece there before, so I took it with me. After cleaning (but without any prep) and inspecting with a hand lens, I discovered, that the subglobular specimen of about 7 cm in size is covered over and over with tiny polygons, about 0.1-0.2 mm in size. So it is a fossil! But what? It -
Coral (7) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)

Hello! Another colonial coral from St. Bartholomä. Contrast is poor and that´s the best I can to with my scrappy scrap. I think, I have not found such a coral before in this formation. And its the second largest colony I have found so far there. My guess is, that it could be Astraeofungia (g, h) or Dimorphastrea (a, b), all pics from Löser et al. (2015). But I am very probably wrong... Thank you very much for your help! Franz Bernhard- 3 replies

Coral (6) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, here is the next coral colony from the Campanian St. Bartholomä-formation in Styria, Austria (Gosau-group), collected 02/10/2019, west of Kalchberg, point 36. This coral colony is intergrown with limestone. There is a naturally weathered cross section and naturally weathered vertical section (but not much to see there). I have cut and polished one end and preservation seems to be not too bad. However, as usual, am rather clueless. I think, it has external pali, so it could belong to Hydnophoropsis?
