  1. Dinosaur Migration

    From Morocco World News : https://www.moroccoworldnews.com/2019/11/286852/flesh-eating-dinosaurs-migrated-between-morocco-and-europe/
  2. Another Moroccan Dromaeosaurid-like Tooth

    So I've just added another new theropod tooth to the collection from the Kem Kem. I'm going to go out on a limb and say it's another contender for a potential dromaeosaurid tooth? • Very laterally compressed • "Pinched" to small degree at base • Mesial carina terminates well above the base • Slight twist to mesial carina • Mesial serration count (midline): 6 or 7 per 1mm • Distal serration count (midline): 3 or 4 per 1mm There are also interdental succuli present between distal denticles; not something I've particularly noticed on other dromaeosaurids, so I'm not sure if that has any impact on tentative ID? Lingual side?: Lateral side?: Cross section: Mesial face: Distal face: Pinch at base: Close-ups:
  3. Hi guys, I have recently acquired this tooth. It was sold as a Tyrannosauridae indet tooth from Bissekty Formation. I thought it could be Timurlengia, but i was not sure. From what I read, not much Timurlengia material has been found.. The tooth is about 2 inch long, and it is a little bit worn out. Its serrations are quite small. The serration density is about 12 denticles per 5mm. I am hoping someone can confirm the species for me?
  4. To prep or not prep?

    I need some advice. I was able to obtain a nice 1.5 inch tarbo tooth that had been in a collection for over 15 years. It was obtained from someone who had direct access to the person who collected it in the field. As such, it was never prepped. I have it exactly as they found it w the dirt, matrix and even plant roots. Should I prep it or leave it “au naturale”. I kinda think it’s cool that way.
  5. Mystery Theropod Tooth - Kem Kem

    I've been browsing online, and come across this tooth. It's listed as Carch, but the serrations look completely wrong to me. The profile of the tooth doesn't particularly scream Carcharodontosaurid or Abelisaurid (though the distal margin does look quite straight) as far as I can judge. Any ideas, anyone? These are the best photos provided... Mesial margin: Distal margin: Distal denticles:
  6. Posible Deltadromeus huge tooth

    Hello! What do you think about this tooth? Posible Deltadromeus? Thank you so much! IMG_3885.mp4
  7. Hello! I have seen this. The seller assures that it is completely natural and is not polished. What do you think? Is it a good piece? Thank you very much
  8. Theropod Femur ID

    Hello All, This is for @Troodon and all other theropod experts. I recently acquired this Femur that is 20 inches and reportedly T rex. I have seen similarly sized nano femurs and this one is more robust and thicker. Polling the community to see it you all think this is Rex. Also, What is the material in the center? It is dark brown and runs the entire length of the bone (the cross section pic has white adhesive on the material in question). Marrow? Matrix? I have sent these pics to Pete Larson and he is MIA (no response yet). Hoping you all can end my debate. Thanks
  9. Potential theropod tooth

    So I was walking in the river near my house one day and found what me and my friend think is a jeuvinile theropod tooth. Me and my friend are good with identifying dinosaurs, we love dinosaurs, but I just want to be sure. It's about 5 1/2 centimeters long, maybe 1/2 centimeter tall, and at the base about 1 centimeters thick. I found it in the Arkansas river right below keystone dam in Oklahoma, United States. It got dropped and broke into three pieces and that is why there are cracks in it.
  10. Theropod claw from France?

    Hi is this a theropod claw from France? it is 6 mm long.
  11. Possible theropod jaw fragment?

    Hi is this a Theropod jaw fragment from the belly river group Canada?
  12. Theropod Tooth - Kem Kem

    As I'm forever on the look out for unidentified theropod teeth, just thought I'd pop this one up for a second/third opinion. It's listed online as Carcharodontosaurus, but I'm not 100% feeling it. The base width appears to be quite narrow, and the serrations seem to strongly increase in size towards the apex. The larger denticles almost look chisel shaped and there's an apparent lack of interdental succuli present too. Probably just positional variation of a Carch, but always worth a double check. Length is approx. 3.5cm. There are sadly no photos of the cross sectional view. Close up of distal denticles:
  13. Theropod dinosaur vertebra?

    Hello. I got this dinosaur vertebra from Nemegt Formation. Size 7cm long. It seems like a theropod caudal vertebra. But I don't know exactly what species it is.
  14. Spinosaurus tooth in need of cleaning

    I just recently bought this Spinosaurus tooth at rock shop. When I looked closer it had a good covering of dust on it from sitting on the shelf for a long time. Its covered in these weird fibers you typically see that are used to make stuffed animals. I think they may have packaged it weird or something. Does anyone know how to get rid of these so my Spinosaurus tooth will look good again?
  15. Morocco - theropod or croc?

    Hi, I recently acquired this eroded, agatized vert, collected in Morocco. It was sold as a theropod, but a friend thinks it’s a crocodilian. Is there any way to tell? Thanks!
  16. Is this a theropod eggshell from the Allen formation Argentina?
  17. ID help: Majungatholus tooth

    Is it possible to verify the ID of this tooth? It is marked as Majungatholus crenatissimus from the Maevarano formation in Madagascar. It measures 27 mm. Thanks.
  18. Allosaurus tooth/locality ID

    Hi everyone, I have 2 questions about a dinosaur tooth I'm hoping to get answered. 1. I was wondering if I could get some help on the ID of this partial tooth. I got it over 10 years ago and was described as Allosaurus. I wanted to check based on the tooth if that seems realistic. The partial measures approx 1 inch/2.5 cm. I understand that without the locality, it can be difficult to be sure what genus/species it belonged to. But that brings me to my second question: 2. Is anyone familiar with Localities in the Morrison Formation that have given bones/teeth the reddish hue that this tooth has? Since Morrison Formation bones and teeth are usually black, I would assume it would be easy to determine the locality if that were true. I think it was described as just being from Wyoming. Thanks!
  19. Found this example for sale, mostly just want to know if it is a real specimen. Thanks for looking.
  20. I've been wavering back and forth as to whether this is a Carcharodontosaurid tooth, or possibly something else? The serration shape doesn't immediately scream Carch to me, and the mesial carina extending 2/3 down the mesial face would usually exclude abelisaurids from the mix (along with the concave distal edge). There does appear to also be a "pinch" at the base, judging by the lighting in the photo and what little can be seen of the cross section (unfortunately, this is the only photo available). Any input would be great to help me put this one to bed!
  21. Hello again everyone! i received the egg I purchased. I took pics outside in sunlight so hopefully some of the can “shed light” on whether this is real or faked. Again, I greatly appreciate everyone’s input. Thanks! Aaron
  22. Hello everyone! I’m Aaron and I’m new here. I just purchased an egg online. I then started reading about how many fakes there are and now I’m very worried. Can anyone give me the skinny on whether it’s real or not? It’s coming from Malaysia and claims to have been part of a private Japanese collection prior to the 80s. I appreciate all your input, thanks!
  23. I’m not familiar with fossils at all so I need help identifying the specimen in the attached pictures. I found this mineral specimen, or at least I thought it was just a large crystal rock, in 2012 at my stepdads house in Placerville, Colorado(San Juan Mountains, down valley from Telluride). I was moving the rock, accidentally dropped it and several pieces broke off. That’s when I wondered if it was a fossil due to the presence of what looks like dried blood, venous cavities, connective tissue, bone, and skin. It is as if it was frozen instantly and turned into stone and crystal, Medusa reminiscent. The San Juan volcanic field is said to be the largest eruption in the world and the proximity of where I found it could explain the strange preservation (if it is in fact a fossil).
  24. I've come across this theropod tooth from Morocco online. I strongly think it's Carcharodontosaurid, but the colouration and general shape doesn't seem to be too far off from what I've seen of Chenanisaurus (mainly looking at photos of @Troodon's). Just to rule out the chance that it does come from the phosphate mines, could anyone provide any input one way or another? The photos provided are the only ones available, I'm afraid. Tooth measures: 4cm.
  25. Unidentified theropod bone

    Hello every. Im looking at purchasing a new item and wanted some advice before I went ahead. It’s from a good seller and said to be an unidentified bone from the hell creek formation. What does everyone thing. Is it fake? What is it? Kind regards Dylan
