  1. Theropod tooth ID ?

    Hello everyone ! Here is 0.65" tooth from carter country ,Hell creek formation , Montana . I personally think that it belong to Theropod maybe ? (I saw very faint serration in this tooth) A good friend of mine told me that due to weird shape of this tooth it could be a Pre-maxillary tooth of maybe Nanotyrannus with feeding damage at the tip. What do you guy think about this tooth ?? as always thank in advance . Guns
  2. Large NJ Cretaceous Bone

    Found this thick bone piece in a new jersey cretaceous creek and wonder if its possible to maybe id since one side has a distinct rough texture while the other is flatter and striated, I would guess either large turtle, mosasaur, or dinosaur. My friend joked its a theropod maxilary skull fragment, but we all know around here that material seems close to impossible to come across haha. Interested to hear any other thoughts.
  3. Madagascar Theropod Tooth?

    Hi all, I bought this tooth recently on an auction site and was wondering what you folks think. The seller bought it at Tucson Fossil show but lost the ID card with the Formation on it, so the locale is missing. Info on the tooth: 1 inch long Supposedly from Madagascar
  4. Mystery Theropod Tooth

    Hi, I received this teeth recently from another forum member and was wondering what others think. These teeth were acquired at a German Fossil Show and were apparently found near the Chinese border. I think they look kinda like Carch teeth. Let me know what you think. The first tooth is 1.1 in long and the base is .3 wide The second tooth is 1.22 long and the base is .5 wide
  5. Hi! I can get this incredible and rare tooth. It is from the Atlas Mountains, Morocco so it’s a Jurassic tooth. Any idea about posible ID? Thank you so much!
  6. This is a large Spinosaur tooth. It has obvious repairs, and some restoration horizontally along the middle of the tooth. However, I'm wondering if it looks composite. The claim is that it isn't composite, but I'm suspicious.
  7. Hi TFF, I am a Dromaeosauridae enthusiast and have been collecting online for a little while now. I want to thank the members here for getting me educated on so many aspects of fossil teeth identification. I want to share my small collection in the hopes this is helpful for some of you in the future. Your critical input is highly appreciated, as always! #1 First up, one of my treasures, a robust Deinonychus antirrhopus tooth from the Cloverly Fm. A big thanks to @StevenJD for letting go of this one – much appreciated! Note the asymmetry in the placement of the carinae, best noticeable from the top view. #2 Representing the Judith River Fm., a cornerstone of my collection, a 1st left premaxillary tooth of Dromaeosaurus albertensis. I just love the way the mesial carina ‘folds’ onto the lingual surface. #3 Another premaxillary tooth from the Judith River Fm., a Zapsalis abradens with prominent ridges. The mesial carina has a nice twist, the cross section looks rather symmetrical, so likely not a 1st or 2nd premax. Distal denticles are hooked towards the tooth tip, but no mesial denticles are present and the tooth is not recurved. So, for now it is labeled as cf. Zapsalis abradens after Currie and Evans 2019, but could eventually be re-labeled as Saurornitholestes langstoni.
  8. Book Suggestion

    I've been dabbling in (becoming obsessed with) books on dinosaurs. Now, I don't know what the type I enjoy are called, but I can describe them and have examples, too. I enjoy a narrative style of writing. A story - not necessarily a field guide or pure facts, but understanding the narrator's experiences during a hunt or explanations of the evolutionary process. Exciting, vivid descriptions where I can imagine I'm there. Immersive prose. Even the history of dinosaurs, in that I want to know about the paleontologists who discovered them, the fraud, smuggling, and other illegal conduct that it involved. The disputes and complexities of hunting dinosaurs. I'm interested in how those discoveries and the circumstances therein transformed societies, more or less a perspective that a cultural historian or sociologist would take. And by no means does this have to be limited to dinosaurs; I'm also interested in Ice Age megafauna and sharks. I am currently enjoying The Rise and fall of the Dinosaurs: A New History of a New World, by Steve Brusatte. Based on that book, I've found others that I believe I'll enjoy: The Gilded Dinosaur: The Fossil War Between E.D. Cope and O.C. Marsh and the Rise of American Science, by Mark Jaffe The Lost Dinosaurs of Egypt: The Astonishing and Unlikely True Story of One of the Twentieth Century's Greatest Paleontological Discoveries, by William Nothdurft Assembling the Dinosaur: Fossil Hunters, Tycoons, and the Making of a Spectacle, by Lukas Rieppel Megafauna: Giant Beasts of Pleistocene South America, by Richard A. Fariña End of the Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals, by Ross D.E. MacPhee Megalodon: Hunting the Hunter, by Mark Renz I would appreciate any further suggestions to fill my already overburdened bookshelf. Thank you, Bellamy
  9. Kem Kem femur?

    Here's a 45 cm / 17.7 inch long bone from the Kem Kem of Morocco. I don't know what animal this belonged to. Maybe a theropod or crocodilian?
  10. Who’s Toe Bone?

    Found this little guy today. Wondering who it belongs to. Looks almost identical to one of my tyrannosaurid toe bones (pic for comparison) but the tyrannosaurid one is much bigger. e; sorry forgot, Dinosaur park fm
  11. Theropods

    I decided to expand my obsession with sharks towards an obsession with theropods. I received my first piece today, a Spinosaur from Morocco, even making a display resembling the rolling deserts of the Sahara for it. This thread will be updated when any further theropod teeth arrive
  12. dinosaur limb bone fragment from Lithuania

    Good evening everyone! Few days ago I found this bone fraction on the southern shore of Dusia lake, Lazdijai district, South Lithuania. The maximum thickness is 6 mm, the thick layers and bone canals are also well visible. There were three times when I noticed very similar bone pieces in fluvial sandstone boulders of Siauliai district (Northern Lithuania) too. By me some limb bone cross sections of theropod dinosaurs look similar but I need professional ID of this bone taxonomy- I am sure it belongs to tetrapod, probably reptile or less likely mammal. Any opinion will be appreciated! Best Regards Domas
  13. Came across this tooth labeled as an abelisaurus belonging to chinanisaurus barbaricus from the Maastrichtian supposedly found in the phosphate mines of the Ouled Abdoun basin. Looks pretty thick to be abelisaurus and comparable to an extent to some carcharodontosaurus teeth. Is there a way tell the difference or will there need to be more specifics involved.
  14. Toe/Finger bone?

    I found this half of a phalanx bone in the upper Dinosaur Park Formation. I’m wondering whether it belongs to a turtle or a small theropod. Would any of you guys know what it is? Thanks!
  15. Claw from HC South Dakota

    Hi all. I have a claw that I am considering. 1.75 inches. No restoration that I can see. Thanks in advance.
  16. Small theropod footprint?

    I found this rock in some landscaping rocks in Arapahoe country Colorado. I know it will be tough. I hope the photos will be enough to get a confirmation that it’s a real footprint and maybe get an I.D There is also a lot of plant material across the whole thing which I hope is proof that it’s fossilized top view with light from the front to outline the detail of the footprint top view back view left view front view right view bottom view Close up of the largest plant piece. I don’t know If the 6 side photos matter with a rock like this but I want to be as accurate as possible.
  17. Theropod teeth with no ID

    So I bought these tooth-fragments at a fossil show back in December in Hamburg, Germany. The seller had a lot of different fossils, including a huge ilium bone of a sauropod from the Kem Kem beds, as well as a tibia from a large indet. theropod (Which according to the seller was Spinosaurus). Other than that, he sold large tooth fragments from the Montana, Hell Creek formation, probably Rex, but no complete Rex teeth. Some dromaeosaurid teeth from the Hell Creek formation, and various herbivorous dinosaur teeth from the same formation too. A lot of ichthyosaur bones from Dotternhausen, Germany. Some fossil amphibian skulls, can't remember where from or what species exact, some of them were still in a matrix, the bones were almost red and looked a bit similar to that of Eryops. He also sold small plastic containers of tooth fragments from China/Mongolia, labelled "Tarbosaurus". I bought one of these containers. The seller told me they were collected near the border between China and Mongolia. I was never truly sure if they were 100% Tarbosaurus, could literally be any other theropod. And considering there was no specific location or formation, it's really hard to tell what I've actually bought. I've had some people write to me, wanting to buy the fragments, and have each and every time told them, that I really can't know for sure what these fragments belonged to. Just recently I bumped into this tooth (as seen below here) online for sale: It is described as a Carcharodontosaurus indet. tooth from the Kem Kem beds of Morocco. And the coloration looked oddly similar to one of the fragments I bought at the fossil show. Now, before you say anything, I know that coloration varies a lot within every location, and some locations may yield fossils that look identical in coloration to other locations' fossils, but I just thought the reddish tone underneath the enamel seemed very familiar in regards to especially 1 of the fragments, which is a partial tooth, and also the most complete one from the little container I bought. (See the partial tooth below): The tooth on the above pictures has the following serration counts: Mesial carinae: ~18 serrations per cm, roughly 2 per mm. Distal carinae: ~20 serrations per cm, roughly 2 per mm. It measures: 2,5 cm at its longest dimension. 1,4 cm wide. About 0,9 cm thick at the thickest point. After seeing the picture of the Carcharodontosaurus indet. tooth for sale, I thought maybe this could be a Kem Kem tooth too. Anyone who's got a guess or a hunch?
  18. Dinosaur Teeth

    Hello. I am considering trading for a few late Cretaceous-era theropod teeth from the American West (I think Wyoming/Montana) and would like some help confirming what they are. They are in ok condition, but I don't have any dinosaur teeth in my collection so I am very excited to bring these in. I'm not sure what formation they are from. I was hoping to narrow these down to a species, or at least get a second opinion. First one is a tooth that I was told is a tyrannosaur ind. Thoughts? I have been reading a lot of what @Troodon has posted so I am tagging him since he seems to be the resident expert. I will post pictures of the others as soon as my fellow trader sends me them. Thank you!
  19. French Theropod tooth?

    Hi again, I saw this tooth online and was wondering what you guys could make of it. The seller calls it a ‘Nuthetes’ tooth but from my knowledge Nuthetes has not been found in France. Something odd to me is the preservation, it just looks off for France. The seller has provided only one photo but a decent amount of information. Let me know what you think. Chevres-Richemont Quarry Chevres-de-Cognac, Charente, SW France France Extremely rare 15mm theropod. Dinosaur, Theropod
  20. Aguja formation theropod tooth

    Found this theropod tooth in my Aguja formation matrix from west Texas. It's narrower and has more serrations than the usual theropod teeth I find there. Any ideas as to what kind? Hash marks are 1mm. Thanks for any help.
  21. Theropod "finger bone"

    I saw this for sale as a theropod finger bone from Hell Creek, Garfield County. I googled theropod finger bones and nothing seems to match at all. To me, It looks more like a hadrosaur finger bone. Any thoughts? Thanks
  22. Looks like we have a new dinosaur from the UK: Vectaerovenator inopinainopinatus The University of Southampton has confirmed that vertebrae discovered at Shanklin on the Isle of Wight in 2019 belong to a new species of Cretaceous era theropod. Believed to be up to 4m long, the dinosaur had notably hollow bones. "Chris Barker, a PhD student at the university who led the study, said: “We were struck by just how hollow this animal was — it’s riddled with air spaces. Parts of its skeleton must have been rather delicate"." News article: https://www.google.com/amp/s/www.bbc.com/news/amp/uk-england-hampshire-53738762 Full publication expected in 'Papers in Palaeontology' soon.
  23. Seems the questions raised around that exciting news of an avian dinosaur preserved in Burmese amber were right after all. The original paper has been retracted by its authors, after the discovery of another fossil closely resembling the previously discovered skull portion of Oculudentavis was classified as a species of lizard, rather than an avian dinosaur. Disappointing for dinosaur fans, but it doesn't change the fact that any Late Cretaceous vertebrate preserved in this way is still an exceptional find.

  24. Indeterminate Kem Kem Theropod Tooth

    It's been a little while since I've popped in to the fossil world properly, but I finally came across another unusual little theropod tooth from the riddle that is the Kem Kem, and just had to pick it up. The overall size and a bit of chunkiness going on here discounts the theorised dromaeosaurid(s) from the locality, and the recurved distal edge doesn't scream abelisaurid. Nothing about it particularly says carcharodontosaurid either, and I can't find a clean match with the morphologies of @Troodon's id guide, though 'morph type 3' is possibly the closest.....so anyone got any thoughts? There's a very strong displacement of the distal carina and the mesial carina extends approx. ⅔ down the mesial face of the tooth. The cross section is oval in shape, with no "pinching" at the base. There are also no interdental sulci or apparent enamel wrinkling (thought the enamel is worn, so it's a little hard to tell). Measurements: CH: 21mm CBL: 8mm CBW: 5mm Serration count (midline): Mesial: 5/1mm Distal: 3/1mm Labial face (?) Lingual face (?) Mesial face Distal face Cross section (anterior of the tooth is oriented upwards) Quick scale reference Denticles (distal carina) Denticles *worn* (mesial carina) Thanks in advance, peeps!
  25. ?Abelisaurid bones

    I decided to sort through some of the Kem Kem bones I got at the Tucson show, and I think I found several Abelisaurid bones. Please let me know if I got it right (Ifezouane formation, Late Cretaceous, Cenomanian) Here is what I think is a distal tibia Here are some Abelisaurid tibias: A - Quilmesaurus, G - Rajasaurus, I - Pycnonemosaurus @LordTrilobite @Troodon
