  1. 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

    Allosaurus ribs or not?

    Hello everyone. A few weeks ago I received this piece of matrix with remains claimed to be Allosaurus, from the Morrison Formation. I'm not sure if they're even dinosaur, but I bought them anyway to experiment with cleaning it. What is highlighted in green, in the first photo, is where I was cleaning up with a dremel engraver. From a previous post that I saw on the forum, where someone was asking about this same fossil (I apologize if I bought it ahead of time), I read that they suggested just exposing the bones a little more, and preparing the matrix. It's
  3. I am a big fan of jurrasic sauropods and I therefore spend most of my time on preparing what is left of them. However, for a change I now started working on a slab of rock that seems to contain a series of fused sacral vertebrae by a theropod. The verts seem to belong to Allosaurus. Maybe not as cool as a sauropod fossil but I think that Allosaurus was a fascinating creature as well. The bones have been collected many years ago at Dana Quarry, Teen Sleep, Wyoming.
  4. Hey there forum folks... anyone in Casper this evening is welcome to come to the Tate Museum's lecture series. These happen every now and then. Tonight's talk is by Joe Peterson of UW (Wisconsin, not Wyoming) at Oshkosh. He will be talking about his research on the Cleveland-Lloyd Allosaurus bonebed in Utah... "How Did they die?" Not in Casper? That's OK, it will be on Facebook Live at 7PM mountain time. We are 7 hrs behind Greenwich. https://www.facebook.com/events/635869241681017 Not on FB? we may try to record it for the museum's YouTube channel
  5. Hi Fossils Preparation Fans, Last week I received 1900kg of unprepared dinosaur bones in plaster jackets. Now my neigborhood thinks I lost my mind and I received a lot of eye-rolling from my wife. However, my two sons (7y and 2.5y old dino fans) and myself think it was an excellent idea to acquire the material. The fossils have been collected in the upper layers of the Morisson Formation. Location: Moffat County, Colorado As always when buying unprepared dinosaur bones you do not really know what you get. However, it seems that most material is Apatosaurus (

    Morrison tooth ID (Allo?)

    As mentioned in the title, I am considering whether this tooth is from Allosaurus sp.? CH 1.7cm CBL 0.9CM CBW 0.35CM MESIAL: 5/MM DISTAL: 5/MM I think mesial serrations extend almost to the base

    Allosaurus Illustration

    Hey everyone, Here is an illustration of an Allosaurus I just finished. I used ink on Bristol board. I plan on doing many more illustrations of other prehistoric animals similar to this and I'll be sure to post those on here too. My two passions are paleontology and art and I strive to learn as much as I can about both. If you want to see some of my other work in the meantime you can visit my website www.mikeosheaart.com. Thanks for looking! -Mike
  9. 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
  10. Hey, headed into Denver tomorrow, passing Dinosaur Ridge in Morrison, then down to Colorado Springs. Can anyone point me in a direction to search for a few fossils along the way? I have heard Florissant is productive, but anywhere else between Denver and Colorado Springs? Thanks for any help,
  11. I sculpt scale model dinosaur skulls (and more) on a popular 3D printing service. I put a lot of research and effort into getting these as accurate as I can. These are my personal copies, painted in acrylic with D.I.Y stands.

    Dinosaur vertebrae

    Hello all I am a new member here.As I don´t have experience in this field,I would appreciate if someone could tell if this vertebrae is original.If so,is it possible to say that it belonged to an Allosaurus? Best Regards, José
  13. I’m wondering if these two teeth (both are from the Morrison Formation in Moffat County, Colorado) have been identified correctly as Allosaurus and Marshosaurus. Here are the measurements of both: Allosaurus: 4cm long serration count is 10/5mm on anterior and posterior carinae base length is 21mm and base width is 13.5 mm (note from dealer: Please note that the base of this tooth is broken and the transition of enamel to root is not present. The base measurement may have been larger.) Marshosaurus: 4cm long se

    Allosaurus or something else

    Hi, Quite interested in this. Supposedly Allosaurus. 1/2 an inch in length. From Morrison Formation, Wyoming. Worn tip, serrations on the back but none on the front. I am wondering if it is too small to be Allosaurus. I'd appreciate any thoughts on the tooth. Thanks

    Morrison Megalosaurid or Allosaurid?

    I bought this tooth and the seller named this 'Allosaurus', but the serrations are more dense and the mesial carina stops far before the root. Is this a megalosaurid or allosaurid? Anyone can help? The base width/base length = 4.2mm/12.3mm Locality: Morrison formation, Wyoming Distal carina Mesial carina
  16. Hi all, Recent find in an old collection. It appears to be a theropod fossil toe bone but I cannot tell what genus or species, or formation. I don’t want to jump to conclusions so I’m putting it out there to all you good people to help hive mind an answer. Thanks!
  17. I have seen constant supply of dinosaur fossils from Hell Creek and Judith River... but not Morrison. I don't see any Allosaurus, Torvosaurus, and Ceratosaurus tooth from the market. Some Jurassic herbivore such as Diplodocus and Camarasaurus are available but not as frequently as Hell Creek herbivores. And I haven't seen any Stegosaurus material as well.. There's no commercial digger working in the Morrison Formation? or there is a legal issue? Or just because they are so rare?
  18. Hi everyone, So today i was researching for a quality tooth, like a Daspletosaur one or an Allosaurus one. Suddendly i notice a tooth that says “Morrison Formation Allosaur/Ceratosaur “shed” tooth” It was in a Matrix, and i never seen in my life a tooth of this caliber, it was very strange. It was like the root was splitted in many pieces, giving you the sensation that the tooth was fused with the matrix. So the question are, what’s the meaning or description of the phrase “shed tooth”? Is a good piece? if you need photo a
  19. Hi I’m looking into buying these three teeth and am wondering if they look good to anyone? Like restoration, repair, composite? And if it’s possible to identify the species? Thank you for any feedback! baby Diplodocid indet, Morrison Formation Theropod indet, Morrison Formation Tyrannosaur indet, Judith River Formation

    Allosaurus tooth?

    Hi all, This is listed as an allosaurus tooth but it can't possibly be? It looks very off, but i figured I'd ask here to see if I'm wrong. I'd say its crocodilian if anything

    Allosaurus Caudal Vertebrae

    This purchase was advertised as an Allosaurus (half) vertebrae obtained from Ernest Shirley inventory. Matches well with exhibits 4,5,6 of the illustration from Charles Gilmore's 1920 report on Osteology of Carniverous Dinosauria... which is considered to be a 5th (?) caudal vertebrae of A fragilis (Antrodemus). I would appreciate any feedback on what details are present in this fossil and perhaps where this may have been collected, as no provenance was provided. There are small pits visible in the side view which may be fossae. I have seen photos of similar looking specim

    Juvenile allosaurus tooth?

    Hey guys, I received this Allosaurus tooth from the Morrisson formation in Wyoming USA. It is tiny (13mm). I was wondering if it was from a Juvenile specimen or just a small adult tooth? Is there any way of telling? Thanks for your help. Regards.

    Morrison Formation Theropods

    Hey everyone, How do you tell the difference between the teeth of theropods from the Morrison formation, such as Allosaurus, Torvosaurus, Marshosaurus, and/or Ceratosaurus? Any information is appreciated! Thanks!

    Allosaurus tooth

    Hello, I saw this for sale and tempted by it, but is it Allo? Seems pretty small to me. And, is it complete? The base seems crooked, so wondering if it may be half a tooth? Labelled as complete but repaired crack. From Morrison Formation. Thanks
