  1. Hello, I got some sad news... The most complete Stegosaurus specimen named "Apex" is about to be sold at auction at the Sotheby's auction house in New York. This specimen was found in 2022 by so called "commercial paleontologist", Jasoon Cooper, who almost immediatly began working with the auction house to detail the specimen and get it sold at the auction house, after he found the fossil on his land. The fossil is the most complete Stegosaurus specimen ever found so far and even preserves skin impressions, wich makes it very requested under scientists. But it is questionable if it is ever going to get studied by them, as it is sadly going to get sold. This is the worst fate for this specimen, as this might be the last time we'll ever see it again, as it could be sold into a private collection. So lets hope, pray for a miracle, that this amazing fossil will find its way into a museum to get studied. What are your thoughts on this topic ? Should it be allowed to sell such important paleontological finds at an auction house to potentialy never see them again and loose much inportant knowledge ? I think not ! https://www.barrons.com/articles/20-foot-stegosaurus-fossil-expected-to-sell-for-6-million-at-sothebys-new-york-95138ff0

Presented on Wednesday, before being exhibited until its sale on July 17, this stegosaurus, recognizable by its pointed plates along the back, and about 150 million years old, impresses with its size (3.3 meters high, 6 meters long) and its state of conservation, with 254 bone fossils out of a total of 319. Including a femur of about 1.10 m. "Apex", its name, "is a very rare animal, and finding one of this size, and so complete, is phenomenal," Cassandra Hatton, head of science and popular culture at Sotheby’s, told AFP. The auction house has estimated its value at between $4 million and $6 million, one of the highest prices on the market, even if this remains far from the record of 31.8 million reached in 2020 in New York for a Tyrannosaurus Rex, the star of dinosaurs. The skeleton of "Apex" was discovered in May 2022 on the private property of a famous paleontologist, Jason Cooper, and Sotheby’s says it has worked with him since the beginning to organize this sale, a guarantee of "transparency" according to the company. In 2022, the auction house Christie’s had to remove a skeleton of T-Rex from the state of Montana a few days before the sale in Hong Kong, due to doubts about the authenticity of parts of the fossil. These auctions have multiplied in recent years, causing debate and frustration among paleontologists who see extraordinary fossils go into the hands of private collectors and escape museums and scientific research. Skeletons of stegosaurs are already on display around the world, but according to Sotheby’s, "Apex" is 30% larger than "Sophie", the most complete specimen shown to the public, at the Natural History Museum in London. "This is a debate that we hear a lot (...) but most of the people I work with give or lend these specimens to museums, they understand the meaning," Cassandra Hatton relativizes. According to her, a museum can always be acquired with the help of a patron. According to Sotheby’s, Jason Cooper has already donated a "significant number" of specimens to institutions "around the world". This dinosaur is the main piece of a wide series of scientific souvenir sales". Translated for you with an automatic translator. Coco

    Unidentified Dinosaur tooth.

    I found this tooth recently at Pett Level in Hastings. I've found loads of teeth including some rare ones.. but nothing like this ..at first I thought maybe ankylosaur or something similar... What's your thoughts ? I've added pictures next to an ankylosaur tooth
  5. Hi everyone! Past summer I visited London for a comic con, but I always try to visit the NHM as well when I am in London. Luckily this time I had an entire day stretched since I also wanted to make some photo's of the collection and I thought, why no share it here. A bit overdue but let's start with my most recent visit to my favorite place on earth: The amazing thing about the NHM is that the entrance is free, but since I like to support the museum and don't like to wait for hours in line I always book a ticket for the current special exhibition which was the Patagotitan skeleton currently on display. I entered from the side entrance were I was greeted by Sophie the Stegosaurus stenops which is the most complete skeleton ever found. Before we headed to the Titanosaur exhibition I came across this cool new Jurassic World Shop with everything JP & JW merchandise. I got myself a 30 year anniversary gilded ticket from Jurassic Park as a souvenir After our quick detour we entered the new temporary exhibition: Titanosaur: Life as the Biggest Dinosaur The actual Patagotitan mayorum femur found in the La Fletcha Ranch, Patagonia, Argentina - Cretaceous, Albian, 101.62 mya Patagotitan scapula, humerus, ulna & radius found in the La Flecha Ranch, Patagonia, Argentina Haestasaurus becklesii skin impression found in Hastings, East Sussex, UK - Cretaceous, Valanginian, 140 - 133 mya Titanosaur coprolite found in Maharashtra, India - Cretaceous, Maastrichtian, 72 - 66 mya Patagotitan mayorum tooth replica
  6. This specimen is about 60 pounds and 19 x 17 x 6 inches. It has what look like tubular areas on one side, and is smooth on the other sides. Although at first glance it may look like a rock, please see other specimens from Nevada that look similar with white mineralization, etc. It is smooth on all sides except where broken. It flares up and down in opposite directions on each end. Possible Suspects: 7 Dinosaurs That Lived in Nevada (And Where to See Fossils Today) One opinion: Looks like a chunk of Morrison dinosaur pelvis..particularly ilium. The busy side is the inner surface where the sacrum fits on, big hole for femur head. Size-wise, Allosaurus, Stegosaurus" Wish the photos were in color, but one looks like the same dark stone with white mineral streaks: https://www.researchgate.net/figure/Right-lateral-view-of-pubic-foot-of-Allosaurus-AMNH-813-Ventral-view-of-pubic_fig1_268274412
  7. Hi. Thanks in advance for help from anyone. I recently bought these bones from someone with access to Bone Cabin Quarry, I am 100% confident these came from there. I can tell that some look like limb bones, #3 looks to me like part of a sauropod vertebra (but I could be wrong). I am fairly new at this. The person said the other Jurassic dinosaurs from the general area included Sauropods: Diplodocus, Camarasaurus, Apatosaurus, also Allosaurus and Stegosaurus. There are 15 bones in the photos, numbered 1-15. If anyone can tell me with any reasonable confidence about any of these, and how they know (I want to learn), it would be a valuable learning experience for me. I forgot to put in a ruler, but the box is 16" by 12". I do appreciate it! Gordon

  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,

  12. Hi all, I have 3 teeth here I need help with The first is a Stegosaurus tooth: It comes from Wyoming, USA. Morrison Formation. It looks like a Stego tooth to me in terms of size and morphology, based off this thread > --- Next, a supposed Barosaurus tooth: It comes from Sundance, Wyoming. Morrison Formation. I cannot find any good literature on Barosaurus teeth. This tooth doesn't seem to have the spade-like shape I usually associate with Camarasaurus teeth. --- Lastly, there is a sauropod tooth from the Cloverly Formation: It comes from Montana, USA. Cloverly Formation. I presume it is a Titanosauriform indet. based off these two papers: https://www.researchgate.net/publication/254315252_The_Beginning_of_the_Sauropod_Dinosaur_Hiatus_in_North_America_Insights_from_the_Lower_Cretaceous_Cloverly_Formation_of_Wyoming https://www.researchgate.net/publication/236886285_Vertebrate_Paleontology_of_the_Cloverly_Formation_Lower_Cretaceous_I_Faunal_Composition_Biogeographic_Relationships_and_Sampling Can I have your thoughts on these 3 teeth? Thank you. - Andy

    Dinosaur Postures

    After the satisfying outcome of my sloth-experiment (changing geoworld megatherium to Thalassocnus) I took another look at some older dinosaur models. Sauropoda- Giraffatitan: "Edutoys Brachiosaurus", added teeth and one cervical vertebra to give him a more erect pose, Changed cervical ribs from medial "monorib". changed leg pose. Thyreophora- Stegosaurus: Glencoe models , changed tail and thagomizer to more modern pose Ceratopsia- Triceratops: Kaiyodo "Wild rush" gave him a treetrunk to look over. Ornithopoda- Parasaurolophus: Geoworld, drilled out intercostal plastik. painted it. Theropoda- Spinosaurus: had it 3d printed. I wonder if I should give it a swimming pose, what do you think?
  14. Hello! I see these spikes from Atlas mountains. I read about stegosaurus (Adratiklit boulahfa) in this formation. Could be a stegosaurus thagomizer? Thank you so much!

    Stegosaurus sketch

    Hi I just sketched this yesterday and would like to share it.
  17. I am looking into building a project for my partner, and she loves the Stegosaurus...so I go looking at whats out there....seems like fossil dorsal armor plates are extremely pricey and other fossils are rare. I know many of them come out of the Morrison Formation and I found some small fossils for sale that claim they are neck scutes...but they are VERY small and the price seems ridiculously low for how rare they are supposed to be. Is there anyway to tell if these are real and actually from the correct species?

    Ornithischian Vertebra

    Hey everyone, recently came across this partial vertebra from the Kimmeridge Clay online, apparently collected south of Oxford. It measures 9.5cm x 8.5cm. The seller tentatively identified it as a Stegosaurid based on the internal pattern visible on the polished side, and subsequently assigned it to Dacentrurus, since it's the only Stegosaurid fitting the time and location. I tried to find more information on these supposed patterns indicative of Stegosaurs without much success, so I'd like to ask: › Is the vertebra actually identifiable on a family level? › If so, what are the defining characteristics and where could I read up about them? Thanks for your help!
  19. 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
  20. 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)
  21. I found this listed as a Stegosaurus stenops ischium (looks like a left illium to me) found in Moffat County, Colorado. It looks mostly real to me, but definitely has some restoration in two places (marked in red) (edit: the smaller area looks like it might be only one side). Is the rest of it all real, or am I missing anything? Something about the area between the restored areas looks slightly off to me, though I lean a bit toward real on that. (edit: removed question on value) I would of course prefer something with no restoration, but Stegosaurus fossils are awfully hard to come by.
  22. 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)
  23. What is a Thyreophoran you may ask? Its the group of armored dinosaurs that existed from the early Jurassic to late Cretaceous. Included are iconic dinosaurs like Stegosaurus and Ankylosaurus. Here are a few photos Tom Raven provided a number of photos: This image of the beautiful Kunbarrasaurus from the Cretaceous of Queensland, Australia And this photoHere's the skull of the basal thyreophoran Scelidosaurus harrisonii from NHM London And, from Beijing, the beautiful lower jaw and articulated cervical vertebrae of the Chinese stegosaur Jiangjunosaurus And the cheeky grin of the Chinese stegosaur Huayangosaurus in Beijing Possible Polacanthus teeth from Bill Blows Susie Maidment provided a photo of tiny tooth from Sophie the Stegosaurus. Crown height ~5 mm She also provided a photo the skull of the basal thyreophoran Emausaurus David Evans photo Here's Zuul crurivastator staring you down The nodosaur Edmontonia at the AMNH Here's a plate and a tail spike from the UK, stegosaur Dacentrurus, from Tom Raven Denversaurus holotype at the Black Hills Institute Gastonia at the Utah Museum of NH Skeleton of the armored early Jurassic, Scutellosaurus in the Museum of Northern Arizona
