  1. Triceratops Jaw Section

    Hey TFF, I found this Triceratops fossil jaw section online and would really like to purchase it. Though, it looks like it had been found in many pieces and prepared okay. I think it would look great in my fossil collection which are mainly dinosaur material, but was wondering if it was worth purchasing because of its condition. What do you guys think? Thanks for your replies!

  3. Hi all, wondering if I could get your opinion on this frill piece? many thanks in advance!
  4. Black Hills Institute Museum

    So I went to the Black Hills Insitute and I made a lot of photos, so I thought I'd share. The Black Hills Institute museum in Hill City is pretty small, it's just one hall. But this one hall is absolutely packed with stuff. This is also the home of the T. rex Stan. Many of the skeletons are casts, but there are plenty of real fossils here as well. The skeleton of Stan. This is the real skeleton and the real skull is placed beside it in the corner. But I didn't even notice that at the time. Skull of Torosaurus. Notice the holes in the frill. Triceratops doesn't have these holes in it's frill. Tylosaurus proriger. Another real specimen. Two Allosaurus skeletons. An Ornithomimid as well as Stan, the Senckenberg Edmontosaurus mummy and Tarbosaurus skull in the background. Skeleton of Albertosaurus, skull of Albertosaurus on the left and skull of Gorgosaurus on the right. A second T. rex skeleton. And a lineup of T. rex skulls in the background. Thescelosaurus and Pachycephalosaurus. Juvenile Edmontosaurus skeleton below the second T. rex skeleton. Cast of the Triceratops Raymond. Crestless Pteranodon on the left as well as a Nyctosaurus? arm/wing at the bottom. Dromaeosaurus in the middle between the legs of the Triceratops and a primitive Sirenian with legs on the right. Bambiraptor and Archaeopteryx skeletons. Foot and skull of Deinonychus and Herrerasaurus, Dromaeosaurus and Eoraptor skulls at the bottom. T. rex arm (cast of Sue) and brian endocast left. Nanotyrannus skull on the right. Mongolian Dinosaurs. Saichania and Saurolophus skulls at the top. Velociraptor skull and oviraptorid partial skeletons below that. Prenocephale, Oviraptor, Archaeornithimimus and Alioramus at the bottom. Tethyshadros top left, and Psittacosaurus nest, and skeletons on the bottom left. Brontosaurus leg in the middle and baby Apatosaurus on the right. Velociraptor and Protoceratops fighting on the far right. Edaphosaurus skeleton. And this is just a small selection of the photos I took. There's just so much stuff here and I only spent a few hours here. The gift shop is also worth a vist btw. I bought a rather nice replica of a tooth from Stan and a Thescelosaurus phalange.
  5. Is this a Triceratops frill section?

    Hi guys, Is this a real Triceratops frill section? I am not really sure the texture on both of the sides are from blood vessels.. So i like your opinions.
  6. I purchased it from eBay. It's from the Lance Formation of Eastern, WY. The exterior surface of the bone is pitted and has grooves just like a Triceratops brow horn. However, all of the Triceratops horns I have seen are conical, meaning they are round in cross section which this fossil is not. The cross section looks more triangular or diamond-like. This fossil has no compression or cracks in it which leads me to believe that the true cross section is more triangular or diamond-like than round in shape. The only other horns/spikes that would have surface bone texture like this and have that shape would be a large Ankylosaur side/shoulder spike. The fossil is partial so I cannot make a 100% definite ID either way so it is possibly a strangely shaped Triceratops brow horn section or a partial Ankylosaur side spike.
  7. Dinosaur bone- Skull fragment?

    Found this in Glendive, Montana (hell creek). The ranch is best known for triceratops and edmontosaurus. The back of it looks concave, almost like a socket, but the front appears naturally rounded, not like a fragment of a long bone. I'm not even sure whether this is a complete bone or a fragment off something larger. The sides have 2 symmetrical curves that look a little like partial eye or nose sockets (picture 2). Perhaps this is a piece of triceratops frill or a juvenile nose horn? It reminds me of a kneecap, but I think I remember reading nonavian dinosaurs lacked kneecaps. The ranch owners had no idea, said it reminded them of a toebone. I'm really curious what you guys make of this one.
  8. Large dinosaur bone- femur? radius?

    Found this in Glendive, Hell Creek formation. The ranch most commonly produces triceratops and hadrosaur, but when I looked at skeletons in a museum I couldn't seem to find a match. The first picture shows what appears to be a ball (part of a socket?) on the top back end of the bone. Any idea? Sorry the pictures aren't very descriptive- I'm a college kid and had to leave the bone at home. I didn't have the time to prep it:(
  9. Triceratops frill?

    Hi all, i win auction on this, can it be a part of Triceratops frill from Hell Creek? I hope yes but i am not sure. I hope you can help me. Thank you for that
  10. Indianapolis Children's Museum

    Hello, I was stopping through Indianapolis and gave their children's museum a try. It was surprisingly enjoyable! The museum covered topics from agriculture to racing to dinosaurs! These photos are from the dinosaur section. I followed the signs to the Dinosphere. I walked through the entrance and down the ramp. At the end of the ramp was a Sarcosuchus cast (no picture sorry). Following the path I emerged into a huge planetarium like structure filled with dinosaurs.
  11. Leptoceratops or Triceratops?

    I can't really tell if this had a single or double root. Cool shed tooth either way. The seller said it's from the Lance Formation, near Newcastle, Wyoming.
  12. Hi all, I just purchased a large Triceratops nasal horn. I'm unfamiliar with Trikes fossils though. I believe it's real(which is why I bought it), but it's a pretty expensive buy, so I'd like your opinions on this piece. It comes from Glendive, Montana.
  13. Dinosaur Teeth

    Hey guys, I'm new to the forum and wanted to share a few Dinosaur teeth I have and see what you guys think of them. Thanks for looking!
  14. Rare dino tooth found in Mississippi!

    https://www.msn.com/en-us/video/wonder/rare-dinosaur-tooth-discovery-sheds-light-on-history-of-north-america/vi-BBBsJL7?ocid=edgsp Check out his cool video! Basically a Ceratopsian tooth discovered in Mississippi. From the Owl Creek Formation of sediments roughly 68-66 myo The gentleman that found it stated that ceratopsid fossils have never been found in the eastern US before!!
  15. My first cast and paint EVER!

    Last Saturday I decided to try something new. I had made a couple of plaster casts in the past, but NEVER painted any before. I don't like painting the walls in my house so never though I would enjoy painting a replica but by golly it was a BLAST! To start with the casting I made 5 teeth, and 3 broke, but 2 came out somewhat decent. I decided to paint my 3 broken ones first just to try it. The fourth tooth in the pictures is a REAL fossil rom Hell Creek, not a cast! I did not have it with me while I was painting so I was just trying to go off of memory. I used a matte sealer for the root, and a high gloss sealer for the crown. They both have a shine to them though! Tell me what you guys and gals think! I promise I won't be offended, in fact if you can offend me you have done something no one has done before! Hmm which one is real? Nope not this one. It could use a little more blending at the crown and root I think. The mold I used seems a bit fabricated from the real deal, but it looks nice! I think the white I added on the tips bothers me the most, but I was trying to give it that shine. Lets see what the real deal looks like. Not the greatest trike tooth out there, but its nice! No idea what is going on with this side of it. A little enamel peel, but it is to be expected. I thought I remembered the crown being darker? Eh, its still a cool piece!

    Hi everyone! Just wanted to share with you all this great Triceratops tooth I recently acquired at a very low price! This is the first dinosaur tooth in my collection, and though it's small, I really like it!
  19. dinosaur wedding....

    Hi folks... It has been a long summer, but it is finally starting to snow here. Thought I would share a few adventures from this past summer. This first post is about a wedding. On the 4th of July, my honey and I got married. We had thought of just going to the judge and get it done, but I showed her a cool spot for a wedding, and she agreed. We got married on a not-yet-excavated dinosaur in the late Cretaceous of eastern Wyoming. Here is the site. It is on a buffalo ranch. That is the herd in the distance. We went out on the spring with some friends who actually like to plan weddings (I don't get it), and this big guy prevented us from going to the site. We had to wait. Of course this led to the question of what if the herd is right here on wedding day? I guess you gotta have something to worry about in a wedding. And here are Pickles and Snickers, two dogs named after food. They are standing on the bones we were to get married on. This is on that same spring recon outing with the wedding planners. The bones are orange-ish. They are encased in a white rock. Between the photographer's feet and the dogs is the sacrum of the animal. I am tentatively IDing this as a ceratopsian. Between the dogs and under Pickles (the black dog) is what I think is the pubis or ischium. And lots of pieces of bone all over the place. The next photo shows the same pile of bones in the foreground. In the background is Becky (future wife in this photo) pointing to another bone coming out of the continuation of the same white rock. I suspect there is quite a bit of this guy in the ground. Fast Forward to the fourth of July. We managed to drag 100 plus people out to this site, an hour plus north of Lusk, Wyoming; 20 plus miles down a dirt road. Our friends the wedding planners did a great job setting up things like the arbor (chuppah in Hebrew) and the shelter for the sun sensitive, like my 80 year old parents. Note the school bus and porta potty on the horizon. The weather was actually quite perfect. We did the ceremony in the morning to avoid the possibility of 100 plus degrees in July. This is incredibly green for this time of year. We had a wet spring and summer. And here is my lovely bride in among the hoodoos. And now for the official ceremony. And there was much rejoicing. But you guys are here for fossils. so on to chapter two.
  20. Triceratops toe bone?

    Hi everyone! I found this in Montana this summer, and I'm pretty sure it's a triceratops digit. If so, is there a way to tell which it is? Just bored and curious. Also, which side would the vale core have attached to? The bumpy, textured side? It was pretty shattered when I found it, so I pieced it together. The white stuff is pales putty I just haven't painted yet. Thank you! -Lauren
  21. Did i find a dinosaur bone?

    I was raking leaves in the backyard, and in the water of a tiny stream in the wooded/swamp area i found what appears to be a large, petrified bone of some kind. Who can tell me what it is? Its hard and brittle like rock and ive found native american artifacts in the same area. Found in Channahon, Illinois.
  22. Reading technical papers (pdf) is like going to the dentist you would rather not do it but you may get something out of it and I'll try one every once and a while. Here is an interesting one that discusses the two Triceratops described in the Hell Creek Formation Triceratops horridus and Triceratops prorsus. The main authors of this paper are pretty well recognized Ceratopsian experts. The two species are basically identical and the only known differences are variations in cranial features like the length of the postorbital and nasal horns. This paper suggest that the long held hypothesis that the differences are just sexual or ontogenetic variations is not valid and is primarily an evolutionary transformation. In the attached figure they placed all known skulls stratigraphically across the entire Hell Creek Formation and found that T. horridus "features" were found only in the lower Hell Creek (L3) while the upper Hell Creek (U3)contained "features" of T. prorsus. The middle Hell Creek (M3) was a transitional zone. This transformation occurred in a relatively short period of time 1-2 million years and it's difficult to argue against sound evidence. The paper again supports the need to have good information on where your specimen comes from. To get a proper species identification it may not only be necessary to know the formation but specific locality. Paper pnas.201313334.pdf FYI ...R. Boessenecker (aka Boesse) was acknowledged in this paper Next we need to settle the debate around Triceratops and Torosaurus .
