  1. I found this Dilophosaurus tooth for sale online and am suspicous of its authenticity. The problem is I don't know a lot (or anything) about dinosaur teeth and how one would go about spotting a cast. Any advice would be appreciated, thanks.
  2. HC Theropod tooth

    Listed on everybody's favorite auction site as a Dromaeosaur or Tyrannosaur tooth. 1/2" long theropod tooth. Hell Creek Frm, I believe it said South Dakota but I will double check that. It was very inexpensive so I went ahead and bought it. If nothing else, seems an excellent candidate for some analysis and it was a good way to test what I have learned without breaking the bank lol So lets see if I have gotten better at this. I believe it is Dromaeosaurid based on the difference in serration size and density. The seller posted good pictures so I could count the denticles. No exact scale in mm but the count was done mid tooth. Distal= 12 Mesial=14/15 The mesial serrations look pretty straight. The denticle shape does not look like the Acheroraptor teeth I have and the density difference is less too.I am not seeing ridges. It does seem to be compressed as a Dromaeosaur would be. I know there will be some work to do when it is in hand with measurements and checking out the base. My smartest option is to tag @Troodon and get his opinion lol For now I will go with Dromaeosaurid indet. I think it could be a DR candidate. Either way, it is a nice tooth with nice serrations and a bargain to boot
  3. an interesting Kem Kem tooth

    I have been working on finding a Dromaeosaur indet tooth from Morocco for a few months. Most of the "raptor" teeth from the Kem Kem beds I have seen labeled as such ended up being more similar to the Abelisaur indet teeth and those I have found were over priced or gone before I could get then. This one is different and appears to fit the general profile of what I am looking for pretty well. I do not think it is a Carch and it does not look like an Abelisaur either. At the very minimum, and hopefully @Troodon agrees with me, it seems a good candidate for a multi-variant analysis. Any thoughts ?
  4. Kem Kem Theropod Tooth

    I do not think I will be able to get much help based on the pictures but I thought I would try.Listed for sale as a Raptor tooth. Most of the Kem Kem teeth I see listed a raptor or Dromaeosaur are better fits for Abelisaur indet teeth. This one looks a little different to me so I thought I would run it by the sharp minds here. This is a small theropod tooth from the Kem Kem beds. I does not look like a Carch so I feel good eliminating that one. Its a little over half an inch long. It does appear that there is a difference in serration size but that could be my eyes seeing what they want to see. The seller did attempt to take better pictures but this is as good as it is going to get I think. Again, it looks different from Abelisaurid teeth I have seen but I am pretty limited in my ID skills. It is a pretty nice tooth either way. Any opinions ?
  5. I have found this theropod tooth in my collection. I bought it as a Carcharodontosaurus tooth, but I'm not sure about the Identification. I would like to hear your opinion on the ID. The tooth is from the Kem Kem Formation (Morocco) and is 51mm (2") in lenght. Serrations on the distal carina can be recognized. Can you help me? Kind regards from Germany!
  6. Acheroratpor tooth confirmation

    Based on the numerous and informative posts of @Troodon, I feel pretty confident that this tooth is an Acheroraptor. It is from the Hell Creek formation, South Dakota. I saw some things that looked diagnostic and the seller provided pics that were pretty good. Anybody want to confirm the ID or present an alternative ?

  10. Decided to make a thread with an update on my collection with better photos and (currently) up to date info on everything with names and location. Sauropods Jobaria tiguidensis (Diplodocoidea) Jurassic (Bathonian-Oxfordian) Tiourarén Formation Marraba, Agadez Region, Niger Size: 1” Sauropoda indet. (Saltasaurus cf.?)

  11. Tyrannosaurus Rex tooth

    From the album My Collection

    Hell Creek Formation, Faith, South Dakota, USA It is a beautiful tooth with no restoration. The tooth has the characteristic d shape profile of a trex tooth on the basal side and this sort of preservation is actually fairly common with tooth also collected from other locations such as Wyoming. The first ever dinosaur tooth that I owned!
  12. What is this dinosaur tooth?

    Hey everyone, There is this small 0.62 inch theropod tooth that I would love if someone could identify. I was thinking it was nanotyrannus or some sort of raptor tooth, but I can’t be too sure. Please help! Please respond if you even know the tiniest bit. Thanks everyone! - FossilsandScience
  13. Juvenile t-rex tooth?

    I stumbled upon a possible rex tooth which is only 0,75 inch and is labeled as a juvenile t-rex. I know that small tyrannosaur teeth is harder to identify but I cant deny that the bulkiness of this makes me believe its a rex tooth. Its found in the hell creek formation of powder river county. Boys and ladies , what do you think?
  14. What are these

    So this is at Texas Tarrant County near a large pond. Not sure if the tooth is crocodile, fish, marine dinosaur or small mammel. The rock with circles on it I'm guessing is an imprint of a shell. And the other one I think is bone in Rock not sure if it's like a tooth if so I guess bovine or triceratops but I'm not sure if it's a recent bone or a bone from the dinosaur era (or if it's a bone at all). Also a general question of how do you know if something is a modern bone or dinosaur bone, I found some level surface and you can see the face of the bone, the rest is in the ground and it's near a pond. If anyone has answers to these questions that will be great. Excuse my lack of knowledge in these areas I'm new and I've just started with no current knowledge in dinosaurs.
  15. Hi all, I just got this tooth from Tolman Bridge area of Alberta. That area falls within Edmonton Group supposedly. I believe it's a hadrosaur maxillary tooth. Any idea what kinda hadrosaur it could be? Thank you for your help.
  16. I found an interesting Thescelosaurus tooth online. No locality was given other than the fact that the dealer claims that the tooth is from the Hell Creek formation. What do you guys think?
  17. Neovenator tooth from Isle of Wight?

    A seller has offered me this Neovenator tooth Isle of Wight. The tooth is 41mm long and is missing the tip, but the surface of the tooth looks nice. The seller is a British seller who owns a fossil website and has sold Iguanadon, another Neovenator and megalosaurus sp? tooth in the past. Please could you let me know your thoughts on this tooth and if the ID might be correct?
  18. Raptor tooth?

    Curious as to what everyone thinks of the id of this tooth. seller calls it Dromaeosaurus but could be from a small rex. location is Powder River county, Montana I wish i could buy this tooth but the seller doesnt ship to the UK... It is a nice small tooth and sorry for the not very good quality pics but they are screenshots from my phone.
  19. Baryonyx tooth?

    Hi there, I was wondering if I could get your opinions on the tooth below. The seller has said it is a Baryonyx but have mentioned that they can't see any serrations so maybe croc? The ridges in the pic stop about 2/3 of the way down to the base of the tooth. I will get location, formation etc if possible from the seller soon. Any thoughts? Thanks!
  20. Seller has advertised this tooth as a Protoceratops anyone familiar with this type of tooth. I highly doubt the seller's ID is correct.. Location info from them is: Djadochta Formation, Gobi Desert,Mongolia Details: 29mm fully rooted upper premaxillary tooth, Protoceratops was the only known ceratopsian with any premaxillary teeth.
