  6. Hi everyone. I'm doing a project on earthworms, and I was hoping you might be able to provide the names of some dinosaurs that existed in at the same time and in the same geographical locations as early earthworms, in periods of both extreme cold, and extreme heat. So for example: X Dinos existed along side worms during the extreme cold of period (or dates) X X Dinos existed along side worms during the extreme heat of period (or dates) X I've been cobbling together bits and pieces from Google and thought it couldn't hurt to seek the advice of experts. Any help would be greatly appreciated. Thanks in advance. Best regards Mike.

    Morroco Tooth ID

    Hi all, Looking for tooth ID. This little guy was sold as an abelisaur but something looks off. Looks almost like a carch. Either way, at the price I'm more than happy with it just looking to confirm the ID. Quite a nice little thing. Kem Kem find in the Taouz area per the seller. Measurement for ID below in mm CH - 9.83 AL - 12.12 CBL - 7.41 CBW 3.27 Denticle on both sides are 13 (over 3mm since tooth is tiny). Thanks for any help!

    Ceratopsian fossil

    I got this fossil from a Wyoming in Tucson, Arizona. I was thinking it's a jugual bone from a Ceratopsian or a Hadrosaur.

    Triceratops material

    Years ago I purchased a Triceratops brow horn that I was told collapsed when the jacket was flipped. There is some material that didn't look the same and I was wondering if it was material from another part of the animal.

    Lance Formation Dinosaur Bones ID

    For Christmas, I'd gotten a box of matrix from the Lance formation. I have some fossils that I am not sure what they are and would like to get your opinions. All of these fossils are from the Lance formation of Weston Co. WY. The first one is I think a theropod ungual, missing both the distal and proximal ends. Here are the pictures. The second one I'm pretty sure is a partial Edmontosaurus metacarpal. The The third one might be a ornithischian ungual. And here is the final one, I think that it might be a jaw section.
  14. http://www.sci-news.com/paleontology/dinosaur-carotenoid-coloration-10354.html Non-avian dinosaurs may have had bright color on their skin, scales and beaks in a manner similar to modern birds, according to a paper published in the journal Evolution. http://cdn.sci-news.com/images/2021/12/image_10354-Orange-Dinosaurs.jpg Link to article: Estimating the distribution of carotenoid coloration in skin and integumentary structures of birds and extinct dinosaurs [paywalled, sadly] My Uni does not have access- I'd love to read this one if someone has a copy-

    The Jurassic Games - a movie

    Has anyone else here seen The Jurassic Games? I’m not saying it’s scientifically accurate or any of the sorts, but for a “B-rate” movie, it’s actually really good! I was really impressed with the graphics. I tend to really like “B-Rate” movies though.

    Montana fossils

    Hello, I recently acquired a small box of fossils from someone who had passed away recently. Inside were many fossils including those pictured. The only indicator of where they are from is that the box says "MONTANA". I can tell there are dromeosaur teeth, hadrosaur teeth, ankylosaur teeth and such. I know the man I got them from would routinely dig in the hell creek formation but I just wanted to make sure there wasn't anything obvious that I'm missing that would indicate that these fossils were collected elsewhere. My guess is that they are from the hell creek formation however. Any feedback is appreciated!!
  18. An overlooked fossil turned out to be a new herbivorous dinosaur with an oddly shaped nose Brighstoneus simmondsi has a big lump around the nostrils, like a chunky alligator.

  19. So this is my 1st time on the trade forum, so I hope I'm doing it right. I have this partial green river formation Eohiodon fish that is about 6 inches long that I self-collected from the split fish layer and I would like to trade it for dinosaur fossils. The fossils that I would want would be tyrannosaur teeth partials, and fossils from the Hell Creek and Judith River formations. Here are the pictures of the fish.
  20. Greetings! This is my first share on this forum. I was looking through my collections, and one thing popped my mind was this tooth -- a tooth of Xiongguanlong baomoensis,which i found in 2014 but I could not give a very conclusive identification until earlier this year. I was lucky enough to travel along with a group of scientists into the Gobi desert in Northern China. That day we was traveling in the border zone of three different provinces, basically middle of nowhere. This basin is where most dinosaur from Gansu found -- including X. baomoensis, Auroraceratop rugosus, Lanzhousaurus magnidens, etc. I found two dozen of borken teeth on a random hill. In the beginning I thought those teeth could be either iguanadon, hadrosaurus or some crocodilians. After collecting them and bringing them back to Beijing, I went focusing on other real-life project (preparing for college, preparing for grad-school, etc.). It became a memory sealed in attic and lost until I was re-examining the crocodilian fossils I found from the same trip. Then my eyes fell on this tooth, which I recalled seeing similar teeth from the Lanzhou Geological Mesuem and labelled X. baimoensis. After a further comparing with other teeth from the same clade in museums in China, I am certain that this tooth could belongs to X. baomoensis. X. baomoensis is one of the most mysterious member of the superfamily Tyrannosauroidea, and only thing I could be sure that they could grow larger than the specimen preserved in Lanzhou -- for I found a large theropodian matatarsal from the same site and it's certainly larger than the skeleton they demonstrates. I put it somewhere in my mountains of boxes, please allows me some time to look for it.

    Hell creek dinosaur fossil

    Good evening, I recently went fossil hunting in Dawson county MT in the Hell Creek formation. I believe that the fossil I collected is a possible dinosaur vertebra. Is there any way to determine what dinosaur this maybe and if it is a vertebra? The measurement is 7 inches long and 4 inches wide. Thank you, geogrl

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.
  23. We’ve just been to the Scottish National Gallery of Modern Art in Edinburgh to see the Ray Harryhausen exhibition. The exhibition contains models and drawings that Ray Harryhausen made for his various movies. It was a great exhibition and well worth a visit. It had all the models from my favourite films like Jason and the Argonauts, Clash of the Titans and the three Sinbad movies. Why this thread on the fossil forum. Well Ray loved dinosaurs and he was lifelong friends with Ray Bradbury who also loved dinosaurs.
