  1. Hands are very important to everyone including Dinosaurs .. here are some photos of your not so ordinary ones ........both herbivore and theropod. Some pretty cool configurations.. Paper on the evolution of Theropod dinosaur Hands https://onlinelibrary.wiley.com/doi/full/10.1111/joa.12719 The evolution of the manus of early theropod dinosaurs is characterized by high inter‐ and intraspecific variation Daniel E. Barta, Sterling J. Nesbitt, Mark A. Norell First published: 08 November 2017 https://doi.org/10.1111/joa.12719 Have to thank Joao Vasco Leite for a bunch of these photos and info.from Twitter From the Triassic dawn of Dinosaurs here is the left hand of Herrerasaurus from Argentina Also from the late Triassic a sauropodomorph Plateosaurus, a beautiful specimen From the Early Jurassic of Argentina the ariticulated hands of the sauropodomorph Adeopapposaurus , wow The Jurassic brought us Dilophosaurus and sorry Jurassic Park fans there is no conclusive scientific evidence that it could spit poison Staying in the Jurassic here is Allosaurus and the different growth stages of its hand claws Also from the Morisson the tiny hand of the herbivore Camptosaurus The Jurassic also brought us the exquisite left forelimb of the stegosaur Gigantspinosaurus, from the Zigong Dinosaur Museum Stegosaurus hand material is quite rare, especially fairly complete ones. Morisson Formation One of the classics, first described by O.C. Marsh back in 1884. The left hand of Ceratosaurus. The bone to the right is metacarpal I, the first bone of the "thumb" . Have to wonder what it was used for. The Late Jurassic theropod Tanycolagreus ..cast From the early Cretaceous the hand of the recently described alvarezsaurid, Bannykus from China Also from the Early Cretaceous of Utah the left hand of Cedrorestes an iguanodontian Everyones favorite the hands of Deinonychus
  2. Hello my name is Tijn. I love Dinosaurs and am already building a decent collection. I already have most species from the Hell Creek Formation, Lance Formation and Judith River Formation. I am mainly interested in species from the Jurassic, triassic or early cretaceous. I've got a couple Dinosaur fossils and shark teeth im willing to trade. I am not looking for anything big but small partial Bones and teeth are fine! Who can help me out? P.S. ill make some pictures of the material i am willing to trade later. Thanks in advance Tijn
  3. I haven't posted in a long time. I used to draw the occasional prehistoric beast but looking back, they always left a lot to be desired. Anyway, I have honed my craft and have since started a drawing degree. I don't do much paleo related drawings as the accuracy needed to be really good scares me! So while I've tried to keep mine reasonably accurate, they are always just for my own enjoyment. Here's a few I've done over the last year or so. First off, something special. This ichthyosaur skull was drawn from life in the Lyme Regis Museum. It was drawn with Jurassic squid ink that was extracted from a fossil found in Lyme. Not easy to draw with as it's quite pale and I couldn't get the contrast I usually like, but a very cool thing to have done. Next up we have a Promicroceras ammonite drawn in brown ink. An Allosaurus skull drawn in ink and copic markers. Quite pleased with how this came out. And finally one I did for part of my degree, my Apoderoceras ammonite. This was done in pen and coloured pencil and was drawn from life. This piece is as accurate as I could make it to the original and was drawn full scale. Hope you like them! Edit: Ignore the order, the pictures came out in the wrong order!
  4. I know that T. rex used to be considered the biggest meat eating theropod dinosaur until the discovery of Giganotosaurus, but Spinosaurus is now considered the biggest theropod of all time. Who first considered Spinosaurus to be larger than T. rex. Is it possible that the emergence of giant carcharodontosaurs and tyrannosaurs in North America and Asia prompted ankylosaurids to develop tail clubs to fend off those predators.
  5. Allosaurus sp.

    From the album My Collection

    Allosaurus sp. Morrison Formation Upper Jurassic Moffat County, Colorado Size: 6cm
  6. Allosaurus Tooth

    Morning all! Wanted to know if this looks like an Allosaurus tooth. Seller says it’s from Dana Quarry in Wyoming. Says it measures 5/8 at longest side.
  7. On Sunday I took a trip to the Natural History Museum in London. I queued up before it opened at 10am and even before then there was a long queue. I have not visited this museum since I was a child and spent an entire day there (10am to 4.30pm - a long time). I was surprised as it is a lot bigger than I remembered and there was so much to see. This place has the most wonderful things and is an incredible place to learn. The museum showcases a Baryonyx, Sophie the Stegosaurus (the world's most complete Stegosaurus) and more! The moving Trex and Deinonychus are also really realistic in the way they move. If you like your dinosaur teeth, the Megalosaurus and Daspletosaurus teeth are out of this world! There is something for everyone in this museum and I would highly recommend that you visit here if you have not already! A lot of the dinosaur specimens are casts taken from other museums but they are still cool to look at. I had taken the photos on my SLR and due to the size of the photos I had to reduce the quality of them to be able to post on the forum which is unfortunate but it's the only way otherwise the photos would take a really long time to load. There are more non-dinosaur related photos that I will be posting at some point later on but may take me some time to pick out. Enjoy the photos from this section of the museum! Blue Zone Dinosaurs (has a mix of some photos of crocs too)
  8. Thoughts on this Allosaurus claw

    Hi there, Let me know your thoughts on this allosaurus claw? I think it has a small bit of resto to it, thanks! Location: Morrison Formation, Bone Cabin Quarry, Wyoming
  9. Carnivorous theropod claw

    Correct me if I'm wrong, but this is definitely not the end of a digit from a large carnivorous theropod. The only potentials from the Morrison formation where it was found, would be different species of ceratasaurs, allosaurs, and torvosaurus, right? and they, along with most carnivorous theropods have claws at the end of every digit, including the little foot&heel stubbies, don't they? wouldnt this have to be from something without claws? Or at least no claw on this?
  10. Allosaurid

    From the album Dinosaurs and Reptiles

    Morrison fm, Moffat county, Colorado 1.6 cm tall
  11. Totally unintentional. I decided to buy this cushion-like material for safely displaying my allosaurus bone on its stand. Backfired on me because I found out that my fossil was sticking to this material. Most of it peeled off fine, but there is some residue left over. Could anyone please tell me the safest way to take the rest off? It’s not a matter of scratching it off, the stuff sticks very well.
  12. Ok, so I know these are kinda small, but hopefully it's good enough to tell. The tyrannosaur fossil was originally compacted, so keep that in mind if there's anything that would be attributed to that. Pic 1:unidentified tyrannosaur 2:stegosaurus 3&4:allosaurus (I know the allo metacarpal may be hard to destinguish, so I'm not expecting anything concrete on that one)
  13. Dinosaur bone? Allosaurus?

    This one I'm actually really worried about, cause I wasn't aware of trying to get something ID'd on here, and so took the seller at their word and bought it. It seemed a little weird, but Ive seen plenty of fossilized bones look weird and "off", so it didn't REALLY strike me as a red flag. after I got it though, the striped coloring looked even weirder in person, and the gravelly matrix on the bottom made it seem much thinner and more off. There was never any claim as to what bone it was, but it's supposed to be from an allosaurus from the Morrison formation. I couldn't fit all the pics in one post, so the rest are following.
  14. 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
  15. My Morrison formation collection

    Here is my Jurassic collection from the Morrison formation. This is a collection I really want to expand so if anyone has any fossils from the Morrison they'd be willing to trade definitely message me. the latest addition to my Morrison formation collection is the large partial Allosaurus vert my parents got me for Christmas. The fossil in the bottom right of the first pic is a chunk of bone, probably Camarasaurus. The fossil in the top right of the first pic is a chunk of bone, probably theropod. Pics 2,3,4= Partial Allosaurus fragilis vertebra, Hanksville Utah Pics 5,6= Allosaurus fragilis vertebra, Wyoming Pics 7,8,9= Allosaurus fragilis tooth, Hanksville Utah

  17. 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
  18. Allosaurus bone fragment?

    I purchased this bone fragment at a fossil show. It's from the Morrison formation of Utah. I suspect it's theropod, most likely Allosaurus because of its hollow nature but I just wanted to get other opinions on it. Thanks everyone!
  19. Allosaurus axe-like skull

    Do you know that an Allosaurus used it head like an axe? Makes it's prey die of blood loss and shock. Do you know any another animal with weird adaptations like that?
  20. Allosaurus fragilis

    From the album Dinosaur teeth

    Large Allosaurus tooth. Measures 3.5" tip to base Jurassic (155-148 myo) Morrison Formation Como Bluff, Wyoming
  21. Allosaurus tooth

    I purchased this tooth yesterday at the NY/NJ 22nd street fossil show and looking to see if the ID given by the dealer is correct. Allosaurus fragilis pre-maxillary tooth Morrison Formation Vernal, Utah. The tooth is 1-1/4" long. I count 3 serrations per mm.
  22. What do you think of this allosaurus tooth with root ?
  23. It's been awhile since I posted so I thought I would share a few recent buys. These two claws are definitely some of my grail fossils. Enjoy!! Allosaurus hand claw, digit 2:
  24. I picked up a number of fossils, minerals, and petrified wood at an estate sale. My assumption was that they were real based on circumstantial evidence (he had a lot of other collectibles that were real and expensive). I will post 3 fossil photos and one "what the @%$# is it" picture. That one was supposedly petrified wood, but I cant find anything else like it on the internet. I am wondering if it is plant based or some type of other organism. The photos of the teeth and claw have a measuring tape next to it. The mystery item's are about 7"-13" long and about 6" tall. What are they and are they real. Claw was supposedly Allosaurus. Teeth are supposed to be a spinosaurus tooth and two big megalodon teeth. Thanks for your help. Also.... I was thinking about giving one to my son for his birthday unless they are worth hundreds of dollars. I am not looking for an appraisal but any ball park idea would be great.
