This tooth was found in Montgomery County, Alabama, and is about 70 million years old. Looking for an ID on the species. I'm pretty sure its a lateral from a goblin shark but I'm not certain.

Campanian hunters and shark experts... have you seen this shark tooth?
EPIKLULSXDDDDD posted a topic in General Fossil Discussion
Hey everyone, I've recently been interested in a weird tooth morphology I have found a couple times in the Middle Campanian Ozan of Austin. At the moment, I have it ID'd as Serratolamna cf. caraibaea based off of a paper on Aguja sharks (https://doi.org/10.1016/j.cretres.2016.08.008). My specimens seem to be a single anterior and single lateral. These teeth appear to have a nutrient groove, multiple pairs of cusplets, smooth labial and lingual faces, and a basal bulge overhanging the root. They are each about 11 mm from root to tip of the cusp. Something to note is that S. caraibae- 8 replies

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 u

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 Card-

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 -
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. -

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 multi -

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. -

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.-

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 (

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

Last January 12, I found some Exogyra sp. oysters in a limestone Late Campanian / Early Maastrichtian strata (SE Pyrenees, Catalonia, Spain), who turned to show abundant beekite rings. I owe to @abyssunder my knowledge of this mineral phenomenon, which, in my area,occurs mainly over laminar-type shells like oysters' (It can occur on other fossils, though). Have you fossils with beekite rings ?

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 lo
