  1. JRF Saurornitholestes langstoni tooth?

    I recently picked up this tooth labeled as dromaeosaur from the Judith River Fm in Hill Co, MT and I think it may be Saurornitholestes langstoni. Can anyone confirm the id for me? Thanks!
  2. Unidentified theropod

    Next tooth up is a "unidentified theropod " tooth from the judith river formation in eastern MT....its CH 8 mm....it has 13 serrations per 3 mm on the posterior of the tooth and 16 per 3 mm on the anterior.......some of the pictures youll see what looks to be ribs on the side of the tooth, i thought zapsalis at first but i dont see the posterior as having a straight edge .....let me know what u all think after viewing the pics! @Troodon
  3. Unidentified Theropod tooth

    Hey everyone i hope you all had a great holiday season....this next tooth in my collection was labled saurornitholestes from the hell creek formation from powder county MT. We know that the only two described raptors from there are dakotaraptor and acheroraptor so im curious to see what you all think of this one. Nanotyrannus perhaps? Unfortunately the anterior serrations have worn off which im sure will make id'ing this tooth difficult but anyway here it is. ....the CH is 9 mm the posterior serrations are 12 per 3 mm. @Troodon
  4. Next up in my collection is this one that was sold to me as a possible saurornitholestes langstoni tooth. From the Judith River Formation in Wheatland Co. MT. CH is 9 mm. Serrations are 15 per 3 mm on the posterior of the tooth and 23 per 3 mm on the anterior of the tooth. @Troodon
  5. Unidentified theropod

    This next tooth in my collection was sold to me as " Unidentified Theropod ". It is from the Judith River Formation in Montana....its CH is 7 mm..its posterior serrations are 16 per 4 mm and its anterior serrations are 19 per 4 mm. what do you guys think it could be from???? @Troodon @fossilsonwheels
  6. Hey everyone! In this post im going to be sharing two teeth from my collection. The first one was sold to me as acheroraptor. Its from the Hell Creek formation in MT and its CH is 7 mm. @Troodon
  7. Dromaeosaurus? Judith River

    Hi all, I recently acquired this tooth labeled as Tyrannosaurid indet. It is 0.5 inch (1,27cm) in length and was found in the Judith River Fm, Wheatstone Co., Montana. The a-typical placement of the mesial carina led me to purchase it thinking it could be a Dromaeosaurus albertensis premaxillary tooth. Serration count over 5mm is 16 mesial and 15 distal. What do you guys think?
  8. I've just received this weird little tooth from the Hell Creek Formation. It was sold to me as a Dromaeosaur premax tooth but I have my doubts as it's quite robust. That said, the other candidate would be a Tyrannosaur and I've never seen a premax tooth with a twist like this. What's more, the carinae are strange - one has nice crisp serrations (I thought they looked a lot like Tyrannosaur serrations) while the other is smooth (it doesn't look like it ever had any serrations). Anyone have any idea what it might be?
  9. Dromaeosaur (cf. Saurornitholestes) Tooth

  10. Hell Creek Claw

    Howdy y’all, I picked up this claw a while ago and wanted to see if an ID was possible. It came from the hell creek and measures at just over an inch long. I saw that Anzu Wylei is hollow and I wasn’t sure if the hollow tube running through it confirms that ID. Thanks everyone!
  11. Tyrannosaur, Dromaeosaur, Other?

    Hello fossil enthusiasts! To identify this fossil, I'd love some help. My uncle had it, and now that he is passed, it was sent to me. He did not leave much information on it, and now we are all curious. He had a note with it that said "W. US LATE CRETACEOUS, DROM / TYRAN". I did a lot of research. It does look like the tooth belonged to one of those animals, but I am having difficulty figuring out which one. The lack of formation does not help. Could anyone here be able to weigh in on whether it came from a dromaeosaur or tyrannosaur? Or maybe some other dinosaur? His and my guess could be way off. I've read a lot of @Troodon posts so I could figure it out (without success), and would love for him or her to weigh in. Of course, all are welcome. Thank you!
  12. I found this lovely velociraptorine claw while searching my Wealden bone bed collection. I enjoyed taking these photos, they are some of the most striking images I have taken of a fossil I think.
  13. Unidentified bone from Kem Kem

    Hey guys, I have bought this bone of the Kem Kem Formation in the internet. But I´m not sure about the identfication. The bone was sell as "Dromaeosaur bone"... The bone is 113mm (4,5 ") in lenght. I hope, that you can hleb me with the ID. Kind regards
  14. I have been looking for an Atrociraptor marshalli tooth for quite awhile. I happened to find someone who had one and he was nice enough to sell it to me, along with a French dromaeosaurid tooth. I got them both in the mail today. Thank you to the seller, who’s a TFF member! Atrociraptor marshalli Drumheller, Alberta Canada Red Deer River badlands Horseshoe Canyon Fm 7/16” Dromaeosauridae sp. indet. Department Charante, France Cherves-de-Cognac Near Chamblanc quarry Berriasian Age 6mm The French tooth’s serrations are so unique. Almost tear-drop shaped toward the tip
  15. Seller listed this as a “raptor toe bone” and it looks like it to me as well. Found in Montana’s HCF. What do you guys think?
  16. Hey guys, Hello I am from Germany. That's why I apologize for my bad English. This tooth (top right in the picture) I have recently screaked from the US. The tooth comes from the Hell Creek Formation (Wyoming). It was sold as a "Raptor" tooth. He is about 7mm (0,28") long. I´m not sure, to which dinosaur the tooth belongs, thats why I asked my question in this forum. I hope, that you can help me! Thank you in advance and kind regards!
  17. Nanotyrannus or Dakotaraptor?

    Hi all, I am new to the forum and new to collecting =) I recently obtained this nice tooth labeled as Dromaeosaur sp. premax. tooth - I would like to get a more refined ID if possible. It was found in the Hell Creek Fm., Powder River Co., Montana and measures 15/16". Denticle count per 5mm is distal 18, mesial 24 (not many denticles visible mesial though). I found a thread here stating it is possible to distinguish Nanotyrannus from Dakotaraptor teeth by the shape of the denticles - however I find this very hard as rookie. Any help is appreciated!
  18. Dakotaraptor tooth?

    I came across this tooth and was wondering if the ID is correct as I haven't had much first hand experience with raptor teeth so far, especially Hell Creek raptors. It's being advertised as a Dakotaraptor steini tooth from the Hell Creek formation. In the description it says it has very fine serrations though I find them hard to spot in the photos as they are a little on the small side. It's pretty small. So could it be Acheroraptor instead?
  19. New Cloverly teeth

    I just got these two beautiful Deinonychus Antirrhopus teeth a few days ago. Both are from Carbon County, Montana’s Cloverly formation. 1/2” front maxillary 5/16”
  20. Fast. Intelligent. Deadly. The "Raptor" is perhaps one of the most famous dinosaur today thanks to Jurassic Park. To many people's surprise however, raptors are heavily feathered and nimbler than movies would have you believe. The Jurassic Park Velociraptor was merely the size of coyote in real life! In fact, their proper family name is 'Dromaeosaurid'. The largest species was Utahraptor, and it grew to the size of a grizzly bear! Dromaeosaurid fossils have been found all over the world. They first appeared during the Cretaceous, though isolated teeth have been found in the mid-Jurassic. Allow me to present my humble collection of Dromaeosaurid teeth. First up, from Cloverly Formation, one of my pride and joy from @hxmendoza A dromaeosaurid from Aguja Formation. I am seeing more Aguja fossils showing up, but dromaeosaurid teeth are still rare. Now, for the dromaeosaurids from the famous Hell Creek Formation. Some of them probably lived alongside T. rex. A big shout-out for @Troodon for getting me started on dromaeosaurids with this very first Acheroraptor!
  21. This is a great fossil forum. A wealth of information. Lots to educate the passionate collector. I want to share a few more of my latest finds with members of this fossil forum. I hope you all enjoy the pics. These are some of my best discoveries made in my Hastings Wealden bonebed collection this past week. First off is this lovely Dromaeosaurid tooth. It took me a few hours, but I managed to prep out both sides. My best find in a while.
  22. Is this a Moroccan raptor tooth?

    I just acquired what I believe to be a dromaeosaurid indet. sp. from the Kem Kem Beds. The tooth measures 19.5 mm long. Serration count on the mid for distal is 14/5mm, and mesial is 20/5mm This tooth is blade-like, and resembles my other raptor teeth. However, Moroccan teeth are often misidentified, so I would like your input.
  23. Possible raptor tooth?

    So.......I've recently gotten into fossil collecting. It's very addicting, I'll admit. Anyway, I recently bought a neat little Kem Kem tooth that was supposedly listed as a "dromaeosaur" or "raptor" tooth. It wasn't too expensive, and of a decent size and quality, so if by chance it wasn't some sort of raptor tooth, I wasn't going to cry about wasting money. I have no idea why, since ignorance is bliss, but I had a sudden urge to look up identifying raptor teeth and stumbled across this impressive site (thank you for existing!!!!). I am now quite certain that my Kem Kem "dromaeosaur" tooth is most likely from some abelisaurid species, which I'm totally fine with since I was planning on buying one anyway. I'll post pictures of it later, since I already own it and can (hopefully) have it identified to the most likely species at my leisure. However, I stumbled across this tooth on my search for elusive raptor teeth. The seller has surprisingly (and respectably) titled it as an unclassified tooth from the Kem Kem area. To my amateur eyes, it looks like it might possibly belong to a raptor? It is supposedly 0.6 inch long. These are the only pictures the seller has provided so far, hopefully they will work. It looks like the mesial serrations (hopefully I'm using that right! New words, yay!) look like they curve slightly to the lingual surface at the base, at least to me.... I roughly sized up a picture of a ruler with millimeters to the pictures of the tooth. There are roughly 4 serrations per millimeter on the mesial side, and 3 per millimeter on the distal. What do you think? Lingual surface is the first picture, labial is the second.
  24. This is my first time posting on this site. I have the opportunity to purchase a potential Dromaeosaur type dinosaur fossil from the Yixian Formation of China. I know there are laws about exporting these types of fossils but the dealer assures me it has been in his possession for a long time. Also, I am willing to take the risk to own an incredible piece of history like this. However, I am not sure if the fossil is real. Based on what I have seen and read the fossil looks like the real deal but would like some other people's advice about it. It is described as a Dromaeosaur type dinosaur which is what the skeleton looks like but would like anyone else's opinion on whether it is authentic or not. Thanks for you help! -Ryan
