  1. Hadrosaurid teeth ID

    Hey everyone, I recently came across these two teeth online. They're both pretty worn down and might no longer possess the features necessary for a more detailed ID, but I'd appreciate your help in confirming that these are actually Hadrosaurid teeth. [images attached are the seller's] Tooth 1 comes from the Judith River Formation of Montana; measuring roughly 9mm [not specified in which direction; I assume depth].  Tooth 2 comes from parts of the Aguja Formation in Western Texas; measuring approximately 13x11mm [not specified along which sides]. Thank you for your help!
  2. What are the odds? A chunk of amber with an aphid fossil pressed against a Dinosaur jawbone from Alberta. https://www.sciencemag.org/news/2019/11/remarkable-fossil-features-insect-trapped-amber-stuck-dinosaur-jaw
  3. Two new from Aguja formation

    I found these two teeth in some matrix that I recently brought back from the Aguja formation in West Texas, Brewster county. I think one is a dromaeosaur tooth and the other a hadrosaur tooth.The serrations on both sides of the theropod tooth are about 6 per 1mm. The scale in the photos is 1mm. What do you think? Thanks for any help.
  4. Hadrosaur Tibia?

    Another piece from the collection at work: Description given is Hadrosaur Tibia. It was in the collection before I started here. It is in 2 distinct pieces, and it has been that way the entire time, since the foam cutouts in its box are shaped for them. It has broken in other places, but I've fixed those with paleobond (although I do have pictures of the broken cross sections somewhere) I'm mostly looking to confirm or disprove whether or not it's existing ID is plausible, and maybe identifying which side (right/left) it's from. Pictures: https://drive.google.com/folderview?id=17X4lkoWQODdUw1G4k12LclGVWYnwcAik
  5. Hadrosaur pubis:

    Another piece from the collection at work: All I've been told is that it was donated to us by a customer at a show in Helena, Montana. Its described as a Hadrosaur pubis. It's clearly seen some restoration work at some point, with many fractures mended together. Its in two pieces currently, which is how it was when I came on the show. One side is gently cambered, the other side is almost unnaturally flat, which is why a pubis bone makes sense to me. It was at one point called a Tyrannosaur scapula, but I'm not clear if that was actually what the donor called it before we decided it was a pubis, or if a former employee was calling it that to make it seem sexier.

  6. Hadrosaur Humerus Repair/Prep

    I recently got this lovely mess of bone, which is a mostly complete hadrosaur right humerus that only requires some assembling. I actually bought this with the idea that it might be a fun project. But then it broke even more in the shipping. So I have my work cut out for me. It's from Judith River formation, Montana. It's hard to tell at the moment, but it seems to be a rather slender humerus. So that would make it more likely to be from the saurolophinae subfamily. But I will look into that some more when I have it assembled. So I will be doing lots of reassembling on this piece as well as prepping away some excess matrix that's still present. Besides the obvious problems, the bone itself is actually in very nice condition with some really smooth cortical bone as well as some lovely visible muscle scars. This is how it looked when I first opened it. Quite a mess. Also a drawing of what it should look like in context. And here I have slightly ordered the pieces. There's 5 big main pieces, three medium pieces and a whole bunch of tiny chunks. One of the bigger pieces that includes the ulnar and radial condyles. The shaft of the bone has had a pretty bad recent fracture. This is also where most of the smaller pieces come from.
  7. New Primitive Hadrosaur From Texas

    Newly described hadrosaur may have used its teeth to scoop or saw. https://blogs.scientificamerican.com/laelaps/paleontologists-unveil-shovel-billed-dinosaur/
  8. Hi all, please be careful whenever you purchase Chinese vertebrate fossils or dinosaur eggs, especially turtles and birds. While some of these may look laughably fake, a search on purchase history reveals that these fossils have been sold over and over again. No prize for guessing which auction site these fossils were sold. I notice three devious techniques used by these sellers: 1) Issuing a certificate, claiming it's been examined by experts etc - Certs mean nothing, unless they are provided by actual museums 2) Selling some real fossils - I've been monitoring this seller's listings for years. Every now and then, a real one shows up. His victims may have bought something genuine from him before, and assumed all his listings are good. 3) Selling replicas alongside his fake fossils - By outright proclaiming some of his listings as replicas, this seller creates the impression that he is a responsible seller who would inform people about the true nature of their purchases. "The best lies have an element of truth" Remember, if you aren't absolutely sure of your purchase, post some pics here on TFF. We have experts who would help you if they can. Also, if you need more info about this listings or the seller, feel free to PM me.
  9. I am in the market to buy some dinosaur eggs and want to make sure these are real before buying them. Any help would be greatly appreciated. Thank you all in advance! I can get more/better pictures if needed.
  10. Did I find a Dino tooth

    Went hunting in the Antlers formation (same age as Cloverly Formation) i found this when looking. It stuck out as it was a different color then nearly every other rock I saw and it resembles some other worn hadrosaur teeth I’ve seen. Known Hadrosaur from the formation is Tenontosaurus. Thanks for the help everyone
  11. Fossil found in 1980's helps point to Hadrosaur origins in American Southwest. https://m.phys.org/news/2019-07-strange-species-duck-billed-dinosaur.html
  12. A Few Small But Cool New Dino Fossils

    We have been working primarily on our shark program material but we did add a few new dinosaur fossils. For the most part they are pretty small in size but add quite a bit to the education we do. These represent some iconic and scientifically important dinosaurs. In addition to these small fossils, we added a 6" Trike frill piece from HC, a smaller piece of a Horseshoe Canyon Ceratopsian frill, and a 2.5" Hadro vert from that formation. These are excellent touch fossils so I am happy ! The small fossils are..... Dromaeosaurus sp. Judith River. I big thank you thank you to @Troodon for some ID help. This is a really nice tooth and I am really excited about this one. We can get into some fun science about the study of tooth wear in determining what dinosaurs ate.
  13. Dino Bone NJ Cretaceous stream

    Any chance this is some sort of dino bone? Found in NJ Cretaceous stream. The strange color, shine and texture just struck my eye outside of the usual tricky rocks.
  14. One of my favorite fossil types. Dinosaur eggs come in all shapes and sizes — from an oval as small as a thumb, to a sphere as big as a basketball. These fossils are often faked by the hundreds, if not thousands, in Chinese factories (China is also the world's richest source of true dinosaur eggs). However, there are also many natural-occurring objects mistaken as dinosaur eggs such as concretions or even fortuitously-shaped rocks. Despite these hurdles, dinosaur eggs remain one of the most desirable of all fossils. NOTE: Dinosaur egg and eggshells, by their nature as an ichnofossil, are challenging for private collectors to identify. None of the IDs I provide here are acceptable on a scientific level as I lack the tools to examine the cross section slices of my eggshells. However, for the sake of documentation I will still provide accurate names and locality here to the best of my ability. First up are my Oviraptorid eggs "Common" Name: Oviraptor egg Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong "Common" Name: Citipati egg Macroolithus yaotunensis 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong Length: 8.78 inches (Note: Has composited eggshells) "Common" Name: Oviraptorid(small type) Nest Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Formation Guangdong
  15. I purchased these two fossils a while ago. Both are from the Hell Creek Formation in South Dakota, and both were described as hadrosaur jaws. They definitely seem to resemble the jaws of hadrosaurs, however I've noticed that the empty tooth rows of ceratopsians look extremely similar (to my untrained eyes), which is making me reconsider the seller's ID. I am hoping that someone out there with more knowledge can state confidently if these are ceratopsian or hadrosaur, and preferably if they can briefly explain why they think so. Bonus points if you can state if these are from the upper or lower jaws, or confidently state the genus. (From my limited research, it seems Edmontosaurus is the only hadrosaur described for the Hell Creek in South Dakota; the most abundant ceratopsian is Triceratops, but Torosaurus is also possible, as is Tatankaceratops, and of course the always popular "not yet described".) Let me know if additional photos would help your ID.
  16. Can anyone indentify the species of hadrosaur or ceratopsian left this leg bone in dinosaur provincial park Alberta Canada?
  17. Hello! Well following the thread of the other post I found 3 eggs of better quality but much more expensive ... What do you think is better preserved and is of better quality? Right now I can only choose one ... Thank you so much.
  18. Hadrosaur Tooth

    From the album Judith River fm. Fossil Finds

    This tooth comes from a hadrosaur of some variety (difficult to assert a genus over one tooth) and is the biggest herbivorous dinosaur tooth in my collection and among my best fossils altogether. It was found by my dad in northern Montana in 2017. It measures over an inch and half in length. If you have any ideas as to what kind of hadrosaur this tooth belongs to feel free to let me know your thoughts.
  19. Fun with 3D Printing Fossils

    So recently my father bought a 3D printer and we've been experimenting printing some cool fossils for a while now. It's a really cool technology. Though it can take a while to print a piece the results are really quite cool. A life size Archaeopteryx can take a few days to print if you don't keep printing during the night. Finishing up the prints afterwards can also take a bit of time. Cleaning off all the supports and sanding down rough surfaces can be quite the process. Then there's painting depending on the desired result of course. There are actually a lot of nice things that can be found for download on the internet. Though many of these models still require a bit of digital cleanup before they could be printed. So here are a number of the painted, unpainted and half painted results. Most of the printed stuff is dinosaur. Photo of the 3D printer and the just finished print of a juvenile Edmontosaurus lower jaw. And here's the same Edmontosaurus jaw print half painted again with the real fossil in mirror image next to it. I scanned the original bone that I then mirrored digitaly so that I could print out the other side of the jaw. Allosaurus hand claw. Clidastes Mosasaur quadrate bone. Skull of the "Prosauropod" Massospondylus. Holotype right lower jaw of Owenodon hoggi, an Iguanodontid. Download link: https://sketchfab.com/3d-models/iguanodon-jawbone-f016ad38ebb647988dafd6bbdc1510d0 1/5th scale Nanotyrannus lancensis skull. The Cleveland specimen. Download link for original file: https://sketchfab.com/3d-models/nanotyrannus-lancensis-young-t-rex-7b0967fa27674d959647868686b6717b One of my favourites. The Eichstatt Archaeopteryx specimen. Download link for original file: https://sketchfab.com/3d-models/eichstatt-archaeopteryx-b71872ad42794ef7883021f2fa9a8079 The right side skeleton of the baby Parasaurolophus "Joe". Printed at 1/5th scale. Right humerus and pedal phalanges printed at life size. Most of the fossil prints are for my collection. But my dad also wanted a few cool things which I painted for him. Skulls of Dodo and Australopithecus Taung Child. Download link for Dodo original file: https://sketchfab.com/3d-models/dodo-264b7746a42b41b2845a499de16f8538 Most are painted roughly to look like their real counter parts.
  20. Hi everyone, I am interested in picking up a hadrosaur egg as a gift to my wife, who is a dinosaur enthusiast. However, I'm worried about picking up a fake. I have found a couple of online listings, and I was wondering if I could get some feedback. As far as I can tell, one of the sellers is from a long-established group in the fossil community but I would like to double check this with someone through private messages. Attached are the photos. The ones with a light blue background are from the first seller (hence Seller_1), and the others are from another (Seller_2).
