  1. Hello, two more verts I'd quite like to add to my (slowly) growing vert collection. First is a a Kem Kem Theropod Caudal Vert mentioned as possibly Carcharodontosaurus which measures 7 cm x 7.5 cm x 7cm. Many thanks again.
  2. Hello, I'm new on this forum and I've got a fossil of which I don't know what it is so I thought I'd ask. It's from the Kem Kem. I don't know which formation but it comes from Taouz. Only one side has been preparated. I haven't preparated the other side because it's a pretty thin bone and I'm afraid it might break. It seems like it has broken and been repaired before. Also, there's an Onchopristis tooth attached to it. I think it might be a skull fragment because of it's odd shape. Specifically I think it might be some theropod's left postorbital of which only the inside has been preparated. But there aren't a lot of Kem Kem skulls to compare it to. So it might be something entirely else. Any ideas as to what it could be would be highly appreciated. Top view Front view
  3. Spinosaur vert

    Any thoughts on this? Another vert I'd like to add to my buy list. From Kem Kem. 17cm long. Dorsal vert. Is the spinosaur label good, or could it be carcharodontosaur? Or, croc? Also, tge brown line down the middle isn't something suspicious ? Like a sign of restoration?
  4. Hi this is a bone I just repaired originally from Morocco, it was broken into two pieces. Please can I have help to identify it. I am guessing Spinosaurus femur. Its 18 inches long, 2 inch diameter at the smallest point and 3.5 inches diameter at the widest, Thank you
  5. Unidentified Theropod Tooth 3

    I was going to wait until tomorrow night to post the 3rd tooth but i got around to taking some pictures and measurements now so here is Unidentified Theropod Tooth #3. Judith River Formation Hill County Montana Crown height 15 mm ( broken base ) Serration count 17 per 5 mm distal 20 per 5 mm mesial I do not see a twist in the mesial carina This tooth is more compressed than the other two teeth the first being dromaeosaurus. Saurornitholestes perhaps?? @Troodon
  6. JRF Unidentified Theropod 2

    This is the second unidentified theropod tooth i just recently received. This tooth has a broken tip and its missing most of the mesial serrations. These are the measurements i observed followed by pictures for your own assessment. TOOTH 2 JUDITH RIVER FORMATION HILL COUNTY MT Crown height 12 mm ( missing tip ) Distal serrations are 3 per mm Mesial are 4 per mm There looks like there is a twist in the mesial carina Dromaeosaurus/Tyrannosaur?? @Troodon
  7. Unidentified Theropod

    Whats up everyone!? So i just received 3 new " Unidentified Theropod " teeth . I will be posting 1 a night for the next 3 nights. All of these teeth were found in the Judith River Formation in Hill County Montana. Heres Tooth #1 Judith River Formation Hill County MT CH 16.5 mm 14 serrations per 5 mm on the distal side of the tooth 17.5 serrations on the mesial side of the tooth Twist present on the mesial carina My thoughts - Dromaeosaurus Albertensis..... Tell me what you all think? @Troodon
  8. Hello there. I recently received a small theropod tooth from the Morrison Formation, without any ID. Part of the tip is missing/worn out. At its longest dimension, the tooth measures 1,1 cm. The serration count (Both mesial and dermal) are 6-7 serrations per mm, and about 18-19 per 3 mm. Anyone who's got a good guess, feel welcome to drop a comment here, cause I have no clue if this is a baby Allosaurus, or a small Marshosaurus, Ornitholestes, Coelurus or something completely different.
  9. Hi, Saw this for sale and was just wondering if this looks like a theropod toe bone or if it could be narrowed down? it is labelled as from Suchomimus but it could instead be from a croc or another theropod if not Suchomimus. It is 10cm in length and comes from the Elhraz Formation in Gadoufaouna, Africa. Thanks.
  10. First Noasauridae from Australia

    Sadly the paper is paywalled https://www.sciencedirect.com/science/article/abs/pii/S1342937X20301234
  11. Theropod Dinosaur Tooth from Morocco ID

    HI, I purchased this Unidentified theropod tooth a few years ago from a seller that sold it as a "Raptor" tooth. It is from the Kem Kem beds from Morocco, during the late Cretaceous Period. It is 1.3 Centimetres (1/2 inch) long. The seller also mentioned that it may likely be from an Abelisaurid. I think that it is most likely an Abelisaurid tooth and I am looking forward to updating it's identification tag in my collection. Yet I need to be certain that I am correctly identifying this tooth. What are your thoughts about what this tooth could be? I apologize if I spelled/addressed the names incorrectly and I would thank you for the correction. Feel free to ask for better quality pictures if you need any.
  12. Theropod tooth (Labelled as Nano)

    Ok, I have given a go at doing some ID on this myself, using the very helpful "identifying theropod teeth from the Hell Creek/Lance Formation." thread. But hit a brick wall. So, if anyone could A) Let me know what this tooth is and B -- If I am on the right track with my amateurish ID attempts, that would be amazing. So, I got to eliminating it as being a Nano (Because Nano teeth are apparently rectangular and this is quite ovalish. And eliminating it as being a small version of a T-rex tooth because it isn't fat and the tip doesn't look right. And eliminated Archaeoraptor as it being a bit big. Eliminated Dakoraptor because the recurve isn't enough. This is my first time having a proper go at IDing a tooth for sale beyond googling similar--so odds are I've missed something obvious or got it completely wrong. So, it is labelled as theropod Nanotyrannus, Lance Formation, 0.5 inches in length. Any help, as always, much appreciated.
  13. https://www.nature.com/articles/s41586-020-2190-3 For your reading pleasure.
  14. Hi all, I am looking for the following publication: Mongelli & Varricchio. 1998. Theropod teeth of the lower Two Medicine Formation (Campanian) of Northwestern Montana. JVP. 18: 65A In particular I am looking for a description of Dromaeosaurus sp. and Dromaeosauridae indet. mentioned in Weishampel. 2004. The Dinosauria. Thanks for your help. JoeS
  15. Tarbosaurus tooth

    I obtained a 1.5 inch tarbosaurus tooth from a very old collection decades ago. One that had not been prepped since the day it was collected. I decided to finally prep it and wanted to show you all the final product. Very happy. Amazing serrations.
  16. Confused

    Digging through some bags of bones, looking for something to work on during the virus crisis. Glued the pieces I and collected and this is what I have. I believe this was collected in Wyoming, near Newcastle. What is it? I think it is Theropod, possibly a partial pubis bone. 10.5inches long, 1.5 inch flat bottom, approx 1 inch depth large marrow pores.
  17. Theropod caudal vertebra?

    Hello, this spring break I found this vertebra in late Campanian sediments from southern Coahuila, Mexico. It comes from the Late Campanian, Cerró del Pueblo Formation, around 73-71 million years. This was found along with marine and terrestrial fossils. It is about 1 cm long (3/8) of an inch, 1 cm in width, and 1.1 cm in height. I want to know what type of dinosaur this vertebra belonged to and whether it’s a caudal vertebra or not. My thoughts on this specimen at the moment, is that it’s probably a caudal (tail) vertebra from a small theropod dinosaur, something like a dromeosaur or a troodontid. I hope some dinosaur experts on this forum can give me more insight on this small vertebra.. Side view Other side Front view Bottom Top view
  18. Black Creek Group

    Here are a couple of dinosaur teeth (tyrannosauroid and hadrosaurid) from Bladen County, North Carolina.
  19. What is your opinion on its classification and if so is the material we have sufficient enough to make it a distinct taxon? Joan Wiffen Reference material
  20. Hi I’m wondering what Ceratosaurus and other horned Theropods used there horns for? I’ve heard it was display but I’ve also heard it was for pushing rivals. Is there any evidence for these? Thank you!!
  21. Removing hard rock matrix

    I have a theropod tooth that has hard rock matrix attached to base. What is the best technique to remove it safely? Thanks in advance.
  22. Hi, I saw this tooth for sale and i am wondering if it looks like it could be a Ceratosaurus tooth. I read something about Ceratosaurus teeth having vertical ridges on the inner crown so i think it could possibly be a good match. It is .75 inches long and comes from the Morrison Formation in Wyoming. Thanks.
  23. Argentine tooth ID

    Hello Everyone, I have had this beautiful Argentine theropod tooth for 18 months now and the previous owner 25-30 years before the ban was introduced. The locality information is a bit flakey, however I thought it would be worth a try to get some kind of ID if possible if there are any Argentine friends out there with some information to hand. I have taken some measurements as follows: Distal - 12 per 5mm Mesial - 12 per 5mm MCL - 18mm MCW - 10mm crown height - 39mm If any further measurements are needed let me know Thanks!
  24. Looking for confirmation on this theropod bone being sold. Seller is identifying it as a theropod (Anzu?) Arctometatarsal from the Hell Creek of Montana, Powder River County.. 10.4" Long. They indicate it cannot definitely provide an ID but the giant raptor Anzu Wylie is a likely candidate be cause other material from this theropod has been found at the quarry. What is a Arctometatarsal?
  25. Dinosaur Tracks

    Thought I would share some of my Acrocanthosaurus tracks in my collection from Texas. These are from the Glen Rose Formation. Anyone who has dino tracks, please feel free to post them here on this thread too...would love to see them! The associated pair are big...both over 20 inches long.
