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 !

I was looking at some of my small theropod teeth, but I was not 100% sure what the best ID for these two teeth were. Any input or help would be appreciated. These were sold as Nanotyrannus, but very small chance of dromaeosaurid and Aguja dromaeosaurid respectively, but I think they might be Richardoestesia cf. gilmorei. The cross-section of the Hell Creek tooth I think rules out Dakotaraptor, or at the very least, does not match the known morphology. Edit: Oops, I used the really funky side of the ruler I'm using. I was going to use the millimeter side, but ending up using a side that measures 20mm per. The measurements are accurate though as I used calipers for that. Hell Creek Formation; Garfield County, Montana CBL: 6mm CBW: 2.4mm Mesial Density: 8-9/mm [Towards end of carinae] Distal Density: 11/2mm (5.5/mm) CH is a bit difficult since the tooth has heavy feeding wear, but it is 8.3mm tall, but could be significantly higher. The mesial carinae does not appear to extend to the base. Aguja Formation; Brewster County, Texas CH 6.4mm CBL 3.7mm CBW 1.4mm Mesial Density: Possibly worn down, or none Distal Density: 16/2mm (8/mm)

Early (Early) Maastrichtian fossils - late Cretaceous the Netherlands
Fossilsforever posted a topic in Fossil Hunting Trips
Hello all, Found some nice fossils. Around Vaals in Limburg (the Netherlands), Cretaceous sediments occur. The Kalksteen van Vijlen (Vijlen chalk), Orsbach Kreide (Orsbach chalk) and Kunrader Kalksteen (Kunrader chalk) or Vetschauer Kalksteen are present. Fossils from these sediments consist of belemnites (Belemnella (Pachybelemnella) sumensis (Jeletzky, 1949) and/or Belemnella (Pachybelemnella) cimbrica (Birkelund, 1957), some forms are described as Belemnella ex gr. sumensis/cimbrica and Belemnitella sp.), sea urchins (Echinocorys sp. including Echinocorys scutata (Leske, 1778) and Cardiaster granulosus (Goldfuss, 1829), oysters (Pycnodonte vesicularis (Lamarck, 1806), shark teeth (for example Carcharias sp., Cretalamna lata (Agassiz, 1843) and Pseudocorax affinis (Münster in Agassiz, 1843) and other fossils. Many fossils are from the Vijlen Chalk (early Early to early Late Maastrichtian). Fossils from the Vijlen 0-3 and Vijlen 4-6 (Vijlen chalk) are approximately between 70.6 and 69.3 million years old (the basis of interval 0 of the Vijlen Member could be dated at 70.6 Ma). Lithology and bioclast contents for intervals 5 (upper part) and 6 of the Vijlen Member at Mamelis (Mamelis 62D-78) have indicated an age of 69.7-69.3 mya. Including the latest part of the late late Maastrichtian (Formatie van Maastricht), fossils can be between 70.6 and 66 million years old.

From the album: Ozan Formation
Gauthieria sp., Travis Co. Campanian, Cretaceous Oct, 2022 My friend Lari gifted me the NSR guidebook and I found this name while reading through it. After some searching online it seems to match up with this urchin I found in the Austin Ozan last year. The tubercles are imperforate and crenulate. Gauthieria has been found up north in the NSR, but is extremely rare. In Austin I've found so far this compressed specimen which I sadly broke trying to extract (still kicking myself) and a smaller fragment still in my collection. I'm gonna have to make a return trip to the spot at some point and attempt to redeem myself! -
Hello, I have found this plant fossil today in the shoulder of a forest road (Hasibach, Geistthal, Styria, Austria). Its freshly split, last pic is photographed under water. Its from the Campanian Afling-Formation, Gosau-Group of Kainach. Any hint to ID is highly welcome! Note: I can not see any venation with a hand lens. I have also the counterpiece, but its worse. Thank you very much for your help! Franz Bernhard

Scyliorhinus taylorensis, Moss Creek Campanian, Cretaceous Jun, 2022 I think this is my favorite from Moss Creek as of yet. I had originally misidentified it as a fractured Cantioscyllium decipiens. Now that I have a microscope, I can fully appreciate the beauty of this ancient cat shark.-

Protolamna borodini, Moss Creek Campanian, Cretaceous Jun, 2022 A rarer tooth that can be first spotted by the prominent wrinkling along the base of the crown. The cusplets are more robust than the sand tigers that co-occur.-

Carcharias holmdelensis, Moss Creek Campanian, Cretaceous Jun, 2022 Differentiating sand tigers is a tough task. Carcharias samhammeri, Carcharias holmdelensis, and Odontaspis aculeatus are three known from the American Campanian and likely make up the majority of these smaller teeth in my opinion. C. holmdelendisis typically has fine striations on the lingual surface and a prominent nutrient groove.-

Carcharias samhammeri, Moss Creek Campanian, Cretaceous Jun, 2022 Differentiating sand tigers is a tough task. Carcharias samhammeri, Carcharias holmdelensis, and Odontaspis aculeatus are three known from the American Campanian and likely make up the majority of these smaller teeth in my opinion. C. samhammeri typically has a smooth lingual surface and prominent nutrient groove. Some have argued that O. aculeatus is only a juvenile form of C. samhammeri. There are some clear similarities. However, O. aculeatus typically has fine striations on the lingual surface and multiple sets of thin and elongated cusplets. The tooth on the far right somewhat resembles O. aculeatus, but I think C. samhammeri is the stronger ID.-

From the album: Texas Campanian (Cretaceous)
Tylosaurus cf. proriger Campanian Texas Ozan fm Tylosaur tooth found in gravel. I'm of the opinion that perhaps the assignment of T. proriger to the Ozan Tylosaurs is hasty - though it's difficult since the obvious differences between these and the holotype are restricted to a single cranial element. Not sure I should say much more on that - while it's not an existing research question it's not my original observation. -

Hemiaster beecheri Campanian Texas The Ozan may be known for inverts around the NSR, but those invertebrates are overshadowed by the charismatic vertebrates characteristic of the formation. Those northern exposures far overshadow its southern exposures, in both vertebrates and especially invertebrates. Now knowing that, this echinoid is a rare find for the Ozan, and its delicate nature means that once exposed it wouldn't even survive a single rain. -
Hello everyone, I have a set of teeth from marine sediment of campanian age from the middle east. After many tries to identify, I couldnt pinpoint them exactly. Some of the rays feel like Rhombodus, but they are not a perfect match... I would Really appreciate any help! Please note there are 6 ray teeth total, just different sides. Also the drawing has (some of) the general types I could distinguish. Thank you! Dolev

I have a few more teeth that I would like confirmation/correction on my ID's. These are also from the Ozan Formation (Cretaceous - Campanian) of North Texas, near the North Sulphur River. The bulk of the small teeth (all less than 7mm) I have picked from the matrix that have cusplets primarily fall into Scapanorhynchus or Cretalamna (with a few other genera, but probably not important here). The teeth shown below I believe to be one of these two genera, but I am uncertain due to a combo of characteristics, so I am asking for some help in deciding what they are or if they are indeterminate (or if they are something else, that is fine to). The first batch are four teeth that I am waffling between Cretalamna appendiculata or Scapanorhynchus texanus lateral teeth. The root shape and cusplet shape look more like the other Cretalamna I have (these have the more triangular cusplets I associate with Cretalamna as opposed to the pointier ones I tend to see on Scapanorhynchus), but they definitely have a nutrient groove so I'm uncertain. What else would/should swing me one way or the other? Any opinions would be appreciated (even a whole different shark if warranted). The second batch I think are Scapanorhynchus, but they are much narrower with less flared roots than other anteriors I have. And they don't look like the symphyseal (or close to the symphesis) teeth that I have seen in publications or discussed on here is some threads. I suppose I should have shown a comparison, but these are really tiny, skinny teeth relative to other small S. texanus teeth I have. Thoughts? Thanks for your help. Mike

I have been trying to finish up my ID's of small teeth I collected last year from Moss Creek in Texas (near the North Sulphur River). This material is Upper Cretaceous, Campanian and I have found at least a dozen genera of sharks with Cretalamna, Scapanorhynchus, Pseudocorax and Squalicorax being the most common forms. I'm going to start with seven teeth that I think may be the same but I can not put a name to. I have been through the references I have specific to this formation or age, elasmo.com, and many very helpful posts on here, but I am still at a loss. In Welton and Farish, they look most like Microcorax crassus, but those are supposed to be somewhat older, and even then there are still some differences. They may be posteriors of one of the more common forms, but I have not found a good match yet, so I'd appreciate some help. I'll tag a few a the folks I know are usually pretty good with this stuff: @Al Dente, @MarcoSr, @ThePhysicist, @fossilsonwheels and a couple I know have collected here recently: @EPIKLULSXDDDDD, @Ironhead42 I do not see any serrations or nutrient grooves on any of them. My pictures from above did not come out very well, so I'll just post a couple (with matching numbers from above) that I think show the patter most of them have (flat on the one side and quite convex on the other with a more expanded root). Thanks for any advice you can offer. Mike

Hello everyone! I have recently been working on a project which includes precisely identifying shark teeth from the Campanian of the middle east. digging in the literature just made it clear that its REALLY messy. There is one promising resource however - Henri Capetta's guide to all mesozoic elasmobranch teeth. Does anybody here have the book or know someone who may have a copy? It would be a TREMENDOUS help! Book: Cappetta H. Chondrichtyes II. Mesozoic and Cenozoic Elasmobranchii: teeth Handbook of Paleoichthyology 3E, second edition,Schweizerbart, Stuttgart, 1–193, 2012. Here are some images of the finds, Welcome to share ideas on them too Dolev

Just to show: it is possible to find fossil pearls. This three come from the campanian of Hannover. They are found in a layer together with a lot of Oysters, all Ostrea semiplana So, when you find Oysters in a bed, look for small balls, might be a pearl This ones are right for a paper we write, will be published end of the years. If someone has pearls from upper cretaceous, let me know, perhaps we can add it not necessary to be campanian age, but upper cretaceous or tertiary, please
