  1. Hello all- It is time again to announce to the masses another exciting Tate Conference. Happening June 7-9 at the Tate Museum in Casper, Wyoming, USA. We have 11 speakers plus a Keynote over dinner lined up to talk about the Morrison Fm and its beasts on Saturday the 8th, and a field trip to the local Jurassic rocks south of Casper on Friday and a second field trip to the historic Como Bluff on Sunday. More info can be found here: https://www.caspercollege.edu/tate-geological-museum/events/conference/ Hope to see a few Forum members in Casper for this. -jpc
  2. Happy Saturday, all! I'm helping a woman to photograph her brother's fossil collection. Everything was collected prior to 1967, after which he left the country. He's still living, but not easy to get a hold of. All of these items have been sitting in storage since then. I understand most of these may not be able to be identified. It's well outside of my wheelhouse, and I imagine many on here may be more familiar with material form the Morrison Formation. I'm going to add one or two per post to make it easy to differentiate. I'm most curious about the first piece which appears to be section of a jaw. If any additional photos are needed, please let me know. Thank you in advance! Label on storage boxes Some labels were included, but they were all jumbled. Fragments from the envelope.
  3. Found this in Colorado where I live, it is brown, the top is smooth and feels polished. There are tiny cracks and holes. They are rough inside Wanted to know what it is, thought maybe a Gastrolith? It was found in a horse pasture laying on the ground. Any help would be appreciated!
  4. 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

    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 what I'm doing. But since I don't have paraloid or butvar, in some parts to reinforce the fragile bones I applied super glue, one that is quite liquid and absorbs very well through the cracks, I apply it by drops using a syringe. Maybe I did wrong, but it is the only thing that could have been done in the absence of something better, and I find that it has stabilized the bones very well so that they do not crumble. In the parts highlighted in blue in the first photo and those that follow, there are spaces in the matrix where there was bone, which surely eroded and only the mold remained. The matrix is quite hard, so I don't think it needs any additional need. My doubts are: a) Are Allosaurus rib fragments effectively treated, as suggested in the publication? b) If they are not, is it possible to tell if it is a theropod, sauropod or other type of animal? Thank you very much in advance.

    Morrison Formation Sediment

    I got a box of sediment from the Morrison Formation. But everything is gray and I am having a lot of trouble determining what's big bone and what's rock. Here is one example. Any advice on this?
  8. Hi, I’ve been wanting to prep some Morrison formation material for a while now however I’ve never prepped Morrison stuff. I have prepped many Hell creek and lance creek fossils. So what are the best tooth for preparing Morrison formation material specifically things like sauropod and theropod vertebrae’s? Thanks!
  9. Hello! Does anyone know any good locations for hunting for dinosaur teeth and bones in the Morrison formation formation specifically in the Colorado and Wyoming area and any good locations for the Hell creek formation in South Dakota. I understand fossil hunters are reluctant to share this information but any information helps!
  10. Hey there, got a pickle for y’all. This one was given to me and it was said it was from Dakota sandstone in central Utah. Not sure if this means the Naturita Formation, very low Mancos Shale, or very high part of the Morrison formation. I was thinking it was a vertebra but with how deep the curve is I am wondering if it is a toe or extremity bone or some sort? added some closeups of it under a microscope, varied from 600x to 2000x magnification
  11. Hello, I have what was traded to me as an ornithischian jaw from the Morrison Formation of Wyoming. It measures 5 cm high and has 2 teeth sockets. I believe it may be a Camptosaurus (due to being the only large ornithischian there) partial jaw, but I cannot exclude the possibility of it being a partial theropod jaw. May I have your thoughts? Thank you.

    Is this a Camarosaurus tooth?

    Hello! I am interested in purchasing this sauropod tooth labeled as a Camarasaurus from Kaycee county Wyoming. This tooth looks very odd to me and doesn’t really look like a Camarasaurus. If it is a Camaroasaurus more information on the species and where the tooth was in the jaw would be great! Thank you!
  13. Hi and thanks for looking at this. While looking for shark teeth in Northwestern New Mexico, I coaxed out a nodule that had half weathered out of the lower section of a sandstone ridge. It was fairly large (approx. 2ft diameter) and was crumbling apart, so I only grabbed the big piece as I thought the quartz looked pretty cool. It cracked open on the ride home and revealed what I think is a fossilized bone. It is a small bone and I'm not sure it can be identified; maybe a confirmation that it is actually a bone fossil would be great. The pictures are terrible right? This phone....

    Camptosaurus Ischium

    Hi folks, I just wanted to share my latest addition to the Jurassic wing of my humble collection! This is a beautiful near complete Camptosaurus ischium. It has great bone quality despite being extremely fragile. It's about 14" long and is just missing some of the flanges but is otherwise complete. The Morrison Formation is one of my favourites and I'm extremely lucky to have secured this specimen, as they don't come around very often in all my years of scouring the internet. I absolutely love it Cheers Marcus

    Type of Dino ID possible from vertebrae?

    My dog and I were out rock hunting in Utah, right outside the dinosaur national monument park boundaries and she started digging furiously at a rock that I had tripped over. I looked back and I couldn’t believe what was sticking up out of the ground. It was a Dino bone vertebrae! I was in complete shock! I helped my dog clear the earth around it and found more and more pieces. Whole pieces. I knew I was supposed to do something but my mind went completely blank. I took the pieces that we had found to a paleontologist that lived on the same block as me. He told me that ‘they aren’t interested in small specimens’, and ‘if you find like a leg bone, that’s another story’. So I kept the pieces that we already had taken. I recently contacted a lady that works in the utah blm network and she contacted like 5 or 6 other people, all of them emailed me and I told them my story. One guy seemed really interested because he had taken a bunch of students out to the site 4 years earlier and hadn’t found anything. I mean, literally, this bone jumped out at me! I tripped over it! Anyways, I read about a man from Moab that basically had the same story happen to him and he was charged with theft and sentenced to prison for taking Dino bone. The guy I was emailing (I am pretty sure his name is Steve) asked me to come show him where I found this dinosaur. I don’t want to go to prison. But I really think this dinosaur needs and deserves to be ‘found’ so nothing else will happen to it.
  16. Hi all, new member here! I was exploring "Dinosaur Ridge" in Colorado near Red Rocks and found this interesting looking piece - any ideas as to what the cut-out bit might be? It's from the Morrison Fossil Area, which I believe produces Cretaceous period fossils. The part in question is about an inch long. Let me know if anybody needs more info/pics to help ID, thanks to all!

    Colorado coprolite?

    Hello I'm Andy. I've been on the collecting scene for about a year. I live in the foothills on the Eastern face of pikes peak. I have found many baculites and some ammonite pieces and all my treasures have been found while walking my great dane. This one is beyond what I've read over the last few months. And help you can give me is greatly appreciated. Thanks

  20. Hi Everyone - I came across this Camarasaurus vertebra and was curious how much restoration has been done to it. I'm trying to train my eye for Morrison Formation material which can be a little tricky . Camarasaurus Tail Vertebrae Jurassic (145 Million – 155 Million Years Ago) Morrison Formation - Wyoming 4 1/4" long Thanks for taking a look!
  21. Quick guide to help identify a few Sauropod teeth from the Morrison Formation. Corrections and additional info always appreciated Please Note: Variations in the morphology of these teeth can vary significantly do to, species, jaw position and ontogenetic changes. This is just a high level guide. Camarasaurus: - Crown is wider than the root - Anterior Teeth are spoon-like and symmetrical, mid and posterior teeth are asymmetrical - The crown enamel ends sharply where the root begins - Wear facet, if present, can be on both sides of the tip From my collection 14.5 cm long and 7 cm long Jaw mechanics showing wear facets Brachiosaurus - Crown are only slightly wider or equal to their root - Teeth are intermediate between spoon-like and peg-like depending on jaw position - The crowns typically have an axial twist relative to the root - Crowns are Conical and Chisel-Shaped - Wear facet, if present, is sharp and at the tip but almost always pointed - The crown enamel blends into the root area. Not has sharp of a cutoff as Camarasaurus From my collection 9.5 cm long From the collection of @hxmendoza from a previous post Jaw mechanics showing wear faceting Diplodocus - Peg-like teeth long and narrow - Slightly curved teeth - Crown enamel blends slightly into the root Jaw Mechanics of Diplodocus showing wear faceting From Supplier, Paleo Gallery Apatosaurus Dont have much published on teeth but from examining ones in my collection they appear to be faceted, grooved toward the base some more than others with sharper edges. More compressed than Diplo. Provided by hxmendoza on a previous post, he made similar comments From Paleo Gallery you can see the faceting References 1) Tooth Replacement of Euhelopus zdanskyi (Dinosauria: Sauropoda) and the Evolution of Titanosaurian Tooth Morphology, Sept 2014 Salakka, Seela 2) Jaw mechanics in sauropod dinosaurs, Jan 1994 Jorge Calvo 3)The dentition of a well-preserved specimen of Camarasaurus sp .: implications for function, tooth replacement, soft part reconstruction, and food intake.

    Animal or Vegetable?

    This is a rock shop purchase. The owner is an expert in dinosaur gembone from the Morrison. He also deals in Hermanophyton ferns, etc so he also knows a bit about paleobotany. But this piece was a mystery to him. Its very well agatized and the fine details are preserved. At first it looks like a limb cast. The exterior is coarsely wrinkled, like bark. The cross-section does not preserve a convincing ring of a bark layer, but there is some kind of concentric character. It has some characteristics of a limb bone. The geometry and size fit that thought. But the rough exterior is a contradiction. The interior has some well developed cell structure, but its patchy. As I write this I am thinking maybe its a petrified root. Or maybe not. The first 2 photos are the same (could not delete) and are a cut and polished face. Last photo is an unpolished cut end. Its a fun one. Enjoy and I look forward to your comments.

    Morrison Formation toe ID

    Got a bit of a potential challenge here today! I recently bought this little toe bone (phalanx or metatarsal I guess) online. It was cheap, I guess because it doesn't have anything in terms of location/age other than Morrison Formation. It is about 6 cm long, 6-ish on its widest point and about 5 high at the highest point. It is quite heavy and stubby. Slightly distorted at the front and the circular parts at the front are partially worn off. Has a piece knocked out of it. Which is kind of neat because you can see the internal bone structure in that part. But the main question of course is: what species is it? Can't imagine this being theropod and it doesn't really match any pictures of stuff like Allosaurus you can find online. I'm leaning towards Camptosaurus or maybe something like one of the stegosaur species, but can't really pin point it. Hoping you guys can help out! More pics in post below.
  24. Hi, this just arrived along with a few other teeth, and I was wondering if it was possible to identify which species it could be. It’s a Crocodile indet. tooth from the Morrison Formation Is all I know. Thank you for any reply’s
