  1. I posted this image in the prep thread and I was widely stated to be an Ichnofossil of infilled burrows. I really don't want to be "that guy" that questions expert opinions, but I'm curious; the burrow seems to have attached branches and areas of tiny "grassy" masses adjacent to it. Could they be crinoid segments/branches and pinnules? I have seen photos of chondrites that have the same kind of appearance. I include 3 of my photos, including one through the eyepiece of my scope, and one internet photo of crinoid pinnules. Thanks. I'll happily accept your opinions, go away now, and not be a pest any further.
  2. My Tyrannosaur research

    Hi I decided to make a post about my main research project right now on Campanian Tyrannosaurs specifically Daspletosaurus. Today I have found something to tell teeth from the Judith River Formation and Dinosaur Park Formation. This could also do with the Tyrannosaurs prey or locality. I found out that Judith River Formation Tyrannosaur teeth serrations are more circular and more round compared to the same time Dinosaur Park Formation Tyrannosaur teeth serrations. The Dinosaur Park Formation Tyrannosaur teeth serrations are more longer skinner and more chiseled like but not like other Tyrannosaur teeth from other areas like T. rex’s teeth serrations. Certain Tyrannosaurs in different areas and times would/could of had unique serration morphology probably dew to there prey. I did this on multiple teeth from the Judith River Formation and Dinosaur Park Formation to strengthen my hypothesis. Any opinions on this topic would be great. I will post more on my research here on this and other topics on the Tyrannosaur/Daspletosaurus. I have been doing research on this Daspletosaurus from the Dinosaur Park Formation and it’s close relatives because it was the first dinosaur fossil I’ve ever found. I’ve liked fossils and dinosaurs since I was 2 but in 2018 I went to Alberta and found my first dinosaur fossil which was a fossil from the Dinosaur Park Formation Daspletosaurus sp. Thats why I have been researching on this topic. The serrations I found on Dinosaur Park Formation Tyrannosaur teeth. The serrations I found on Judith River Formation Tyrannosaur teeth.
  3. Almost 2 weeks ago I went with a small group from the rockhound club up to the Vancouver Island Paleontology Museum and the Courtenay & District Museum to see their fossils. Weather was too crummy to do an actual collecting field trip at any place! I guess it's OK to post pics here. I won't post anybody's face. The lighting and some of the display cases themselves presented problems for photography at both places, besides which it was kind of a whirlwind tour, so these shots are the best I could do. I'd say the poor lighting was the worst thing about both places, but we're dealing with small museums with small budgets here, so I figure that can be excused. First, Graham Beard gave us an informative tour of the VIPS in Qualicum Beach. It is a one-room fossil display, aimed primarily at educating the public, and Graham's tour was likewise, which suited us fine as most of the rockhounds know next to nothing about fossils. I think we all got more out of it than we would have if we'd been left to view it all on our own. He not only explained what was interesting about many of the pieces but also recounted the stories around how some of them were collected or acquired. He started at the 'types of preservation' showcase, which featured a piece from the Appian Way site up toward Campbell River which contains Eocene plants. It had been sliced and peeled to reveal fine cross-section detail of the plants. Several new species have been described from here. If you look closely at the slab leaning at an angle on the stand you can see a sheet partly peeled off: Heteromorphic ammonites from Hornby Island and V.I.: The big dark one in front, I have a piece of the same taxon from Mt Tzuhalem. Mine is missing the crook part but looks identical to the straight part. I thought it was from my mountain until Graham told me it was from up along the Inland Island Hwy near Courtenay. (Nothing to collect there now, as that was when the hwy was being built or widened). It didn't have a label and Graham couldn't remember so I'm still not sure what it's called!

  5. 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). This particular site is far from being exploited... Third: My last trip to this formation two days ago (12/18/2019) was very short and "designed" to bring back lesser specimens, duds, and some cutting rejects to three different sites. However, the trip resulted also in 4 fossils, two of them again from point 25-North: This is the 7th chaetetid-stromatoporoid sponge I have found in this formation, 6 of them came from this spot. I like these fossils more and more! And a rather nice (for this formation ) rudist matrix specimen: The two other fossils found this day were a small Hippurites colliciatus and a colonial coral from point 32; both specimens need to be cut and polished. Thanks for your interest and happy winter/christmas/new year fossil hunting! Franz Bernhard

  7. 400 Million years in 4 hours

    400 Million years in 4 hours The small-scale geology of Austria makes it possible to observe and collect invertebrate marine fossils from a time span of nearly 400 Million years (Ma) within a few hours and at a distance of only about 10 km: - 395 Ma old Devonian (Eifelian) corals - Ölberg - 80 Ma old Cretaceous (Campanian) rudists – St. Bartholomä - 12 Ma old Miocene (Serravallian/Sarmatian) gastropods - Waldhof I did this special hunting trip west of Graz at October 22, 2019 as a "feasibility study". The youngest and oldest fossils can simply be picked from the ground (or photographed); the “middle-agers” require some searching; I succeeded to find a few good specimens within one hour. Weather was perfect with nearly 25°C (!). Simplified geological map of Styria with the visited area west of Graz (red rectangle). Geological map of the visited area (1:50.000), composed of two adjoining map sheets. Red numbers denote visited fossil sites (and their age in Million years). Note the fossil sign in the blue formation in the upper middle of the map. This is the upper Devonian Steinberg-formation with goniatites. These fossils are not abundant, though, so I have never explored this hill… Topo map of the area. Red numbers denote fossil sites, A and B are sites of landscape pics. Just to show off some landscape: View from point “A” in Steinberg towards west. K = Kreuzegg mountain (570 m, Campanian St. Bartholomä-formation) at a distance of ca. 5 km. A = Plateau-like Amering mountain (2187 m, high-grade metamorphic rocks) at a distance of ca. 40 km. View from point “B” at Kreuzegg mountain towards north to southeast. Pano composed of 4 individual pics, spanning about 140°. Labeled mountains and hills in the background are: S = Schöckl (1445 m, Devonian epimetamorphic limestone) at a distance of ca. 20 km. P = Plabutsch mountain (754 m, namesake of the fossil-rich Eifelian Plabutsch-formation) and B = Buchkogel mountain (656 m), both at distance of ca. 10 km and located immediately to the west of Graz. Ölberg and Waldhof sites are between P and B, but not visible. Note the about 1000 m high, largely deforested mountains at the left side of the pano (Mühlberg, Pleschkogel etc., lower Devonian, dolomitic Flösserkogel-formation). The severe deforestation of these hills is due to a strong storm in 2008 (“Paula”). Continued...

  10. Late Cretaceous chalk in North America

    Hey everyone I know I've been lately rather inactive on TFF; I was held back by fieldwork and other reasons (though do expect some posts about the fieldwork next weekend ). But anyway, onto what I came to talk about... Would anyone know of some good exposures of Late Cretaceous chalk in Canada or USA? I'm thinking specifically about Campanian chalk or, even better, Maastrichtian chalk.. It would be great if the exposed chalk is very fossiliferous, of course. Thanks for any help! -Christian
  11. Hi, Recently I found this quite complete (both valves) oyster shell in an Upper Campanian to Lower Maastrichtian strata in SE of Pyrenees. My guess is Amphidonte pyrenaicum, a widespread species in the Tethys at this epoch. Supposing my guess is correct, problem is that I find that species named as (from older to newer papers): Exogyra pyrenaica, Ceratostreon pyrenaicum, Amphidonte pyrenaicum, Amphidonte (Amphidonte) pyrenaicum, and Amphidonte (Amphidonte) pyrenaica. So, I understand that former Exogyra genus has been splitted, Anyone knows of a paper about this issue? Thanks
  12. 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. First without any success. Sure, every piece was fossiliferous limestone, but even not a rudist fragment among them. But then, only a few minutes before I had to leave, it was there! Just pulled out of the dark hole to the left of the specimen: A slender, slightly bend Vaccinites vesiculosus. The apex is broken off (pillars are visible there) and it is also broken at the top end, but it is quite aesthetic and elegant, that´s at least my thinking . I like it very much! Ok, back to work : This is the main dig site at point 25 as of today, 09/24/2019. There are no longer many clasts of fossiliferous limestone in the scree, mostly sandstone and marl. The orange bucket in the upper left pic contains clasts of fossiliferous limestone, the black bucket waste material (marl and sandstone). Today I have removed 23 buckets (10 Liter) of waste and 3 buckets of fossiliferous limestone from the dig site. Scale bar is 1 m. In the lower left pic, piles of fossiliferous limestone are visible, the waste material is dumped to the left (not visible). In the lower left corner, cutting rejects are deposited. At the right edge of the lower right pic, fragments and partials of rudist are deposited. This was probably my last hunting trip to St. Bartholomä for some time. I would like to do more prospecting and light surface collecting during my next trips. I am not really the born digger, I like prospecting more, but sometimes, I just have to dig . Thanks for looking! Franz Bernhard
  13. 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 from my parking place and from the way to the heaps: Some impressions of the heaps. First row is the western, lowermost end of the east-west trending with a small dig. A small, but quite nice radiolitid from this hole is to the left of the pocket knife. A second radiolitid was also found there. Second row shows some parts of the upper, north-south trending heaps. Third row shows to the left a fragment of a Hippurites nabresinensis (nearly in-situ, a small part was exposed). To the right, a freshly exposed, but still nearly in-situ Vaccinites is visible to the right of the red object; a small part of this rudist was also already exposed. Its the area shown in the pic above. Well, no pocket knife, already lost...
  14. 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

  16. colorful belemnites

    I wanted to share a few belemnites in my collection, personaly I think they are a bit of an underrated fossil and could use a little more attention. They can be very beautiful and colorful and of course they are cephalopods Belemnites from Eben-Emael ( Belgium ) Maastrichtian: Belemnites from the area of Mons ( Belgium ) Maastrichtian: Belemnites of the area of Mons (Belgium ) Campanian (2 brachiopods infiltrated the picture )
  17. Hadrosaur Humerus Repair/Prep

    I recently got this lovely mess of bone, which is a mostly complete hadrosaur right humerus that only requires some assembling. I actually bought this with the idea that it might be a fun project. But then it broke even more in the shipping. So I have my work cut out for me. It's from Judith River formation, Montana. It's hard to tell at the moment, but it seems to be a rather slender humerus. So that would make it more likely to be from the saurolophinae subfamily. But I will look into that some more when I have it assembled. So I will be doing lots of reassembling on this piece as well as prepping away some excess matrix that's still present. Besides the obvious problems, the bone itself is actually in very nice condition with some really smooth cortical bone as well as some lovely visible muscle scars. This is how it looked when I first opened it. Quite a mess. Also a drawing of what it should look like in context. And here I have slightly ordered the pieces. There's 5 big main pieces, three medium pieces and a whole bunch of tiny chunks. One of the bigger pieces that includes the ulnar and radial condyles. The shaft of the bone has had a pretty bad recent fracture. This is also where most of the smaller pieces come from.
  18. Another completely unknown to me from the Campanian St. Bartholomä-formation, Gosau-group, Eastern Alps: They were found in a polished slab of one of the typical fossiliferous limestone clasts of the Rudist-bearing "Knödelbrekzie" of this formation. There are many of these unknowns in this specimen, but not so well preserved as (A); they are mostly only fragments and also often strongly recrystallized (below C). The two elongated, greenish, inhomogeneous blobs in the right part of the specimen seem to be the same, containing crushed and poorly preserved fragments similar to (A). It could be, that there is some branching involved. Maybe this is also the case with the two green, interconnected, circular blobs to the right of the elongated blobs. One of these circular blobs contains remnants of the fossil in question. One of the unknwons has some corallite-like structures (C), but I don´t think, its a coral. However, there seem to be also some real corals in this specimen (D). I am totally at a loss, what A, B, C etc. could be. Possibilities see title, but it could be even something different. Every hint is appreciated, it´s ok if you only know the phylum . Remark: All of the phyla listed in the title are know (mentioned, not described) from similar clasts of the Campanian Wietersdorf Gosau-sediments in Carinthia. Many thanks! Franz Bernhard
  19. 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. After cleaning at home, some axial ripping was visible in a few of the tubes. Good sign!! Could be another phaceloid coral colony! After cutting it was clear: It is!! And it is in some parts rather well preserved, the best specimen of this type so far. According to the work above, it seems to belong to the genus Procladocora. Four species of this genus are described for Rußbach-Gosau: P. gracilis, P. aff. exiguis, P. formosa, P. sp. In some corallites, septal insertion of 6 / 6 / 12 can be observed. The maximum outer diameter of the corallites is about 3 mm. This would place this specimen within the species P. gracilis. But the age is different and the occurrences are geographically about 200 km apart. So it is better to stick to Procladocora sp. Thanks for looking! Franz Bernhard
  20. Strange NJ Cretaceous Fish Bone

    Hi everyone, I have this partial fish bone from the Late Campanian of New Jersey, 72 Ma. I have never seen this type of bone structure before, but for some reason it reminds me of some type of rostrum (billfish?). It is a little over an inch at greatest dimension. Any ideas are appreciated!
  21. Hi, Some weeks ago, I found those spatangoid echinoids in my usual Upper campanian/Lower Maastrichtian hunting zone of SE of Pyrenees: I think they fit well with Diplodetus brevistella, as shown in http://www.echinologia.com/galeries/micrasteridae/index.html#diplodetus But, I found no other references of Diplodetus in the Pyrenees, and hardly in distant zones of Spain, which makes me doubt (Diplodetus is a genus mostly found in Northern Europe)
  22. Aristotle's lantern ?

    Hi, I found this crushed echinoid in an Upper Campanian/Lower Maastrichtian stage of the Pyrenees. "Not much of a piece", I tought (likely a Micropsis or a Phymosomatoid). But I wonder if this can be its crushed Aristotle's lantern: Close-up: The other side:
