  1. Hi everyone! I have my eye on an interesting claw from Hell Creek in Carter County Montana on "that website" and was wondering if anyone could give some extra insight. The seller listed it as Alvarezsaurus, which I had honestly never heard of before, and a quick search revealed that genus is much older than Hell Creek and from South America. I think they might mean it's from the Alvarezsauridae family, but in any event before I try for it I figured I should ask for an outside opinion on what this is from since this group is new to me.

    Small Hell Creek theropod tooth

    Hey all, What are your thoughts on this on this one? Thanks, as always, for your help! From the hell creek formation, Hill County, Montana CH: 13.5mm CBL: 7.2mm CBW: 3.0mm Mesial serration density: about 5.5/mm Distal serration density: about 4.5/mm

    Theropod foot bones?

    Hello! I found these foot bones (called tarsals I believe?) from Wibaux county Mt in the Hell Creek formation. The seller says that there’s a possibility these are theropod bones, specifically saying bone 1 might be a dromeosaur bone, and bone 2 could possibly be from a tyrannosaur. I looked at some photos online and the only real difference I could tell is some of the dromeosaur bones could be proportionally longer. I also don’t know how to tell if these are even from dinosaurs or some other reptile/bird. Any help would be appreciated! Thanks.

    Wounded tooth?

    Hey all, Do you think it's safe to say that this fella went mouth-to-mouth with a contemporary (antemortem) and got the other's serrations stamped on the tip of his front tooth? In this first pic, it almost looks like the tooth got raked against another's serrations, starting or ending with the point of significant imprint.
  5. Hi all. This specimen is advertised online as a dinosaur metacarpal from Taouz. I don't know much about Maroccan dinosaur bones, but I wouldn't be surprised if this bone a complete fake, composited or heavily restored (some areas appear very smooth) item. Pictures are pretty bad, but it is all I have got. What do you think? If it is real, would it be possible to id it to some level? Thanks!

    Nano or Dromie?

    Hi all, If you have a chance, I'm curious to know what you think this tooth from hell creek, SD likely is. I don't have a provenance, but the seller does the digs themselves is exclusively in the Hell Creek. It was labelled Dromaeosaurus, so we know it needs an fix. I think the thing I'm struggling most with is whether the very weak fluting (or shrink wrapped appearance) is sufficient to call it Acheroraptor rather than Nanotyrannus. I'm thinking that the strong recurve also suggests possibly Acheroraptor. The base has enough pinch that Dakotaraptor is probably out, but
  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

    Carch? Indet?

    Hey all, During a discussion about different locations in the Kem Kem, this tooth came up. It always puzzled me, but I figured it was just an odd Carch tooth. But the reaction I got sounded like it was worth taking some better pics of. Any thoughts? Kem Kem is all I've got CH: 26mm CBL: 16mm CBW: 7.75mm Mesial serration density: about 2.75/mm Distal serration density: about 2.75/mm Thank you!!
  9. Hi, Was wondering what type of claw this could be. It isn't complete and quite small at just over 4cm, but it looks robust which makes me think maybe either Theropod or Sauropod (or maybe croc). It comes from the Elhraz Formation, so maybe if theropod, Suchomimus might be an option. Is something like this identifiable and could it be a hand claw? or is there a lack of papers about claw fossils from this formation. Thank you!
  10. Hi everyone! I recently acquired some really interesting little Theropod teeth from the Hell Creek Formation of Carter County Montana. I have my suspicions on IDs, but I would really like a second opinion. Tooth 1: My first thought with this little guy was Troodontid, but I have no experience with Troodontid teeth. It might also be a really tiny Dromaeosaur. No serrations or even a trace of serrations on the mesial side is kind of a unique feature. It doesn't look like they were there and wore off either, it looks like there were never serrations on that side.
  11. What do you guys think? Full size dromaeosaurus from East Asia I think. Seems too good to be sold

    Are these Juvenile Rexes?

    Hi everyone! I acquired these two pretty recently and immediately though Juvenile Rex, but after that other one I figured I should be more careful and ask for a second opinion. Both are from the Hell Creek of Powder River County, Montana. Tooth 1: Crown Height: 11 mm Crown Base Length: 5.5 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density: 4 per mm Tooth 2: Crown Height: 14 mm Crown Base length: 7 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density:
  13. Hi, I have been offered a Kem Kem claw which I think is a theropod hand claw, but when it comes to claws from the Kem Kem, I have little idea on how to spot composites or claws made out of carved bone (or at least, I worry too much about Kem Kem claws no matter how good they seem). Wanted to ask if someone can help me determine if this claw is real, and if so, are there any repairs done on it. Thank you!
  14. I found something from our favorite auction site that looks very interesting, however I have my doubts if it is legitimate or allosaurus, and would like to hear someone else's input. Seller describes the item as a fused humerus and radius, but I am guessing they mean ulna and radius, of an Allosaurus, found in the morrison formation. Do anyone have information regarding whether these bones even fuse in theropods, or whether they even resemble the ulna/radius bones of Allosaurus? Thanks

    Theropod tooth Hell Creek

    I got another odd man out in my hell creek group. What do you think? The hell creek formation CH: 11mm CBL: 6mm CBW: 3mm Mesial serration density: about 5.5/mm Distal serration density: about 4/mm Serration shape: Hard to tell, given that it looks like half of each denticle is worn away Base cross-section: Almond Mesial carina: Straight Thanks in advance!

    Allosaurus tooth?

    Hi Everyone! I've been looking around at some potential Allosaurus teeth I'd like to buy but before I do I'd like to make sure that's actually what they are and learn how to id them, as I'm assuming the Jurassic fossil market is as rife with misidentification as the Cretaceous one. Here's one I'm curious about, very clearly a Theropod tooth. Apparently found in the Morrison Formation of Washakie County, Wyoming and measures 1.08 Inches in a straight line measurement. So what do you all think? Is it Allosaurus? How do you know? Is it even possible to pin a Morrison tooth o
  17. Hi All, I'm new to this forum and thought I'd send over images of my theropod teeth plus one extremely impressive sauropod from Madagascar. Hope you like them! Paul

    Possible Dromaeosaurid Tooth?

    Hello, So I came across this seller offering a “Dromaeosaurus tooth”, and I was wondering if it was properly ID’d. The serrations are pretty worn up front, so I’m unsure. The only locality that I can get is Judith River Formation, Montana. (IIRC, Dromaeosaurus isn’t found in the Judith River Formation.) The dimensions of the tooth are 1.3 inches long, 0.2 inches wide, and 0.1 inches thick. It’s been a little while since I’ve last posted here, because I was busy with life and university. Hopefully I did things correctly.
  19. Listed as a partial tibia and being hollow, possible theropod? Very small--just under 1inch. Is there any other possibilities for such a small, hollow bone? Could it be a type of small reptile for instance? Also, is it Tibia, or another type of bone? Wealden Clay, Hastings Sub Group Thanks for the help

    Theropod Teeth from Niger

    Hello, I've got 5 teeth from Niger I thought I'd post all at once to get ID input. Thanks for any help you can offer. (1) Labeled Afrovenator. Tiouraren Formation of the Agadez region of Niger: Posterior looks to be about 2.75/mm Anterior looks to be about 2.5/mm (2) Labeled Afrovenator. Tiouraren Formation (Niger) Posterior looks to be about 2.25/mm Anterior
  21. Sorry if I break any rules or etiquette in regard to identifying these teeth. At the estate sale I asked the person in charge of the items about the teeth, and they said they had no idea where they were from or what dinosaur/s it could be. I looked through some fossil websites and they looked most similar to raptor teeth however I am unsure. Thanks in advance for any help! I can take more pictures if that would help as well.

    A visit from the ghost of hell creek?

    Hi, What do you think? From the hell creek formation, Harding Co, South Dakota CH: 12.7mm is showing, but with the significant tip wear facet, I estimate at least 14mm CBL: 7.5mm CBW: 3.3mm Mesial serration density: about 7/mm !! Distal serration density: about 4.5/mm Serration shape: raptor (I think) Base cross-section: Oval Mesial carina: Straight Sorry, I'm stuck with caliper pics at the moment, but might

    A minute Hell Creek theropod tooth?

    This tooth is from Harding County, Hell Creek formation. Now--it is tiny. 1mm long, so is the smallest tooth I own by far, but it has quite clear serrtations that can be photographed. It came with a few others and this one stands out because of its fatness and squatness (most of the others are long, relatively speaking) I am wondering if possibly, maybe, hopefully .... I may have a baby/infant Rex? Now, unfortunately, the base is a bit thin--but could that be because of the size of the tooth? It's quite an unusual one and hope it can be ID'd
