This topic is a short continuation of my previous topic on my Squalicorax collection, which can be seen here: This time I have chosen to show my Pseudocorax teeth. As with the Squalicorax teeth, I am open for trades and buying new additions. The oldest examples of Pseudocorax in my collection come from the Lower Campanian. Like the Squalicorax genus, they start off as a genus with very small teeth. Pseudocorax granti (x16) Ozan Formation Lower Campanian Moss Creek, Fannin County, Texas, United States of America See you guy tomorrow, Sander

Hello, I found this fossil last spring break, in Coahuila, Mexico. It comes from the late Campanian (73-71 Myrs) Cerro del Pueblo formation. I found several fossils at the same location where I found this fossil. Some of the fossils I found include Cerithium snails, several species of Physidae freshwater snails, Inoceramus sp., petrified wood with teredolites, ammonite fragments, a caudal vertebra from a Hadrosaurid, and plenty of dinosaur bone fragments. The formation is a mess, it’s composed of layers that were deposited in marine, and terrestrial environments, as well as rivers and possibly swamps. Even though I’m very knowledgeable of the formation, and the fossils that have been found there I still have no idea as to what this specimen is. My best guess at the moment is that it’s some type of plant material maybe a fruit or a seed. There have been numerous plant fossils found at the formation, including fruits. I also think this could be embedded in a coprolite, with the rounded object being embedded in it. Let me know what you guys think about it.

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 be a better locality west of Geistthal, but have not found anything there during previous visits. Last but not least some typical landscape of the Gosau-basin of Kainach. Cherry trees etc. are blooming at the moment, but everything was soooo try. But we finally had some rain during last night! Franz Bernhard

I found a tooth in Bladen County, NC at a site on the Cape Fear River near Elizabethtown. The site is Upper Cretaceous, and is Upper Campanian in age. It's in the Black Creek Group. I know that the tooth isn't in the best of shape, but hopefully is identifiable. All the Mosasaur teeth I had collected there before are a black color. I noticed this tooth is also curved from side to side. I don't know if it's a Plesiosaur or Mosasaur tooth. Both have been found at this site, but the Plesiosaur is far less common.

Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so small that the photo's are not as sharp as I would have liked, but I think they are good enough. It is Squalicorax primaevus from the Middle Albian Argiles tégulines of Courcelles, Aube Department, France. See you guys tomorrow, Sander

Hello, I've put teeth here for Id a couple of times and always received a satisfactory answer. I hope you can help me this time too. It is about this Ceratopsidae tooth from the Niobrara Formationn (Wyoming). Unfortunately no fossils of this group are known from this formation and I therefore wanted to ask you if you have any idea what species of dinosaurs the tooth could belong to. The tooth is 1,5cm in size. I hope if you can help me with this! Best regards from Germany!

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.

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.

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!

Campanian news from the St. Bartholomä-formation, Gosau-group, Eastern Alps (Styria, Austria)
FranzBernhard posted a topic in Fossil Hunting Trips
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

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...

The left humerus of a juvenile hadrosaur. Found near Hamilton. The closest formation is Two Medicine formation. The deltopectoral crest seems fairly robust for such a young animal so I'm leaning towards this being Lambeosaurine instead of Saurolophine, which would make it most likely Hypacrosaurus. The shape also fits quite well with a juvenile Hypacrosaurus I have restored some small areas where there were large holes. But I have left the largest area of damage due to it being a little unclear as to how robust or slender that area would have been.

Late Cretaceous chalk in North America
The Amateur Paleontologist posted a topic in General Fossil Discussion
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 -
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

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. 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

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 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...

The right humerus of a subadult hadrosaur. The morphology matches that of saurolophinae. Members of Brachylophosaurini seem to match most closely. Brachylophosaurus canadensis is the closest match. There is some lateromedial crushing that makes the whole deltopectoral crest look more slender.
