  1. Some different Dino displays

    We starting switching up our displays for the different styles of Dinosaur programs we do. The formation displays are great but we wanted to try this style for the Dino report programs. I like how these are shaping up and they help the flow of the presentations. We can switch fossils between the different displays and this gives us some flexibility. The first one completed is the Ceratopsians. We have two different decent sized Trike frill pieces and various teeth from Hell Creek. The Leptoceratops tooth is from Lance Creek and we have two JRF teeth. From the Aguja, we have a frill piece. Lastly a toe bone and a small frill piece from Horseshoe Canyon. We use a 7” Hell Creek vert and a 3” vert from Horseshoe as touch fossils. The kids like seeing the various pieces of different Ceratopsians from different locations.
  2. Ankylosaur or ceratopsian

    Hi i was wondering how to tell ankylosaur from ceratopsian vertabrea? Thanks.
  3. Is this akylosaur skin

    Is this akylosaur skin it matches the euoplcephalus skin above found in dinosaur provincial park.
  4. Ankylosaur armor?

    I was hoping some folks on the forum could confirm this ID for me. I found this interesting little piece in the hell creek formation of South Dakota back in July with Paleoprospectors. I was told by one of the guides that it could potentially be a piece of skull armor from a young ankylosaur. I want to know what everyone here thinks.
  5. Hi all, I am considering buying this fossil and I was wondering whether it is a ankylosaur spike or a bone? I was wondering what peoples opinions of this are? Many Thanks, Danny
  6. Spikes or Scutes

    Found several, 25-30 of these yesterday. Seem more like spikes to me. Can anyone confirm if they are from an Ankylosaur?
  7. Fossil of new dinosaur discovered in Texas by Hillsboro paleontologist, KWTX, April 22, 2019 https://www.kwtx.com/content/news/Fossil-of-new-dinosaur-discovered-in-Texas-by-Hillsboro-paleontologist--508882331.html New Dinosaur Discovered in Texas, Now What Should We Call It, Stryker, The 1063 Buzz, April 22, 2019 https://1063thebuzz.com/new-dinosaur-discovered-in-texas-now-what-should-we-call-it/ Yours, Paul H.
  8. Closer inspection to my collection of bone pieces from trips to the Lance formation in Wyoming has resulted in me wondering if I had a few pieces of Ankylosaur osteoderm in my possession. I want to know what the folks on the forum think.
  9. Ankylosaur or Nodosaur Scute ?

    One of my goals is to bring a very tactile element to our education programs. I think adding a piece of dino armor is going to be a real hit with the kids. I have been trying to brush up on ankylosaur and nodosaur scutes in preparation of getting one at some point in the near future. I am not to the level of being able to recognize them yet but I did see one in our price range. I am not sure about this one. The seller lists it as being from Hell Creek. It is 2.5"x1.5" and is 1/2 inch thick. Anybody have any thoughts about this one ?
  10. Hell Creek Formation Rooted Tooth ID

    I recently purchased this tooth from a collector at the Tucson Gem and Mineral Show. He wasn't sure if the tooth was Pachy or Thescelosaur but upon looking at it more closely I'm not even sure if it isn't some sort of Ankylosaur. Any help would be great. The tooth was found in the Hell Creek Formation Perkins County, SD. Thanks! Ryan
  11. Mystery dinosaur Horn

    Here's another Cretaceous western fossil that needs an ID. Its either from Hell Creek or Lance Creek (will have to check my records again), and I initially purchased it as a young triceratops nasal horn. After looking at it some more, I'm wondering if it might be an ankylosaur spike, or maybe something else. Thoughts?
  12. This report is a bit late, but better late than never! During late July through to mid August 2018 i was on a research trip to study a new Canadian dinosaur footprint site for my Masters degree project. I am based in Australia, and this was the first time i had been to Canada! So of course i had to make the most of it and pay a visit to the world renowned Dinosaur Provincial Park in southern Alberta, arguably the richest site in the world for dinosaur fossils. The park is the best exposure of the Dinosaur Park Formation (which it is now named after), which dates to about 76.5 million years ago during the mid-Campanian. I had long read about this location and watched it on documentaries for so many years growing up as a kid. Finally being there in person was very surreal! I was quite lucky and managed to go on a long, extended walk through the park with one of the guides for about 6 hours in total. In this relatively short amount of time i observed so many amazing fossils. I must have been completely desensitised within the first 30 minutes! It really is incredible how much fossil material there is lying all over the park. In Australia, whole scientific papers are written about isolated or fragmentary dinosaur bones, yet here they were just lying everywhere! The pictures really speak for themselves. As said, all of these fossils were observed in the field during a single days visit to the park. As this is a World Heritage site, nothing was taken, all finds were put straight back onto the ground after i took these photos. It's a VERY hard thing to do, but rules are rules. The only thing that was removed from the park on my trip was my best find of the day... a near-perfect 5.3 cm tyrannosaur tooth from Gorgosaurus!!!! This find was too special to leave behind, so the park tour guide GPS marked the location and brought it back for display, likely at the visitor centre or as a demonstration piece for their guided tours. To say that i have found a tyrannosaur tooth is a great honour! You may remember it from the July 2018 VFOTM poll. Without further ado, here are the pics! It is going to take multiple posts to fit them all in, so scroll all the way down to see them all! Various dinosaur vertebrae. Everything from hadrosaurs (duck billed dinosaurs) and ceratopsians (horned dinosaurs) to theropods (two legged meat eaters) and ankylosaurs (armoured dinosaurs). These were so common! I would probably pick a new one up every 5 minutes or so. Ankylosaur tooth
  13. Hello. This little tooth popped up on my radar recently. This tooth is .5 inch in length and it comes from the Judith River Formation. The seller describes it as Euoplocephalus but I'm not sure if that ID is correct. Interestingly I've found that this tooth has a slight resemblance to teeth from Edmontonia, but I have found no information on Edmontonia being described from the Judith River Formation. I know this is likely Ankylosaur indet. because there is still so much Ankylosaur material yet to be described, but is an ID on this tooth possible? Thanks for the help! I posted a reference photo of an Edmontonia tooth credited to @Troodon's collection.
  14. These are both from the Aguja Formation of Texas. Just would like to confirm the ID supplied by the seller. Thanks in advance for the help. Ankylosaur foot claw, ungual 3.1" Hadrosaur, Kritosaurus Toe bone 13"
  15. Recent acquisitions...new pics

    Here are some new pictures of fossil number two from an earlier post. I posted this piece a few days ago. I'm hoping new pictures may help further the identification as either a ceratops horn core or piece of ankylosaur armor. If it's horn core I'm curious, is it possible it's not nose horn core but maybe a side of the face horn from a variety of ceratops? If ankylosaur armor, would this be called a spike or a scute? Thank you again for any and all assistance.
  16. Possible scute?

    Hey everyone, I was out hiking in southern Alberta when i discovered this guy. I thought it could possibly be a scute? Maybe from an ankylosaur? The reason why i think it could be a scute is necause of the ridge in the centre. Any help with identification would be appreciated!
  17. Hi guys, On a auction website I bought a collection of small Dinosaur/ Mammal fossils from the Lance Formation in Wyoming. First photo: Have you any idea which teeth belong to what dinosaur or Mammal? And is the central left piece an crocodile scute? Second and third photo : Is it true, this could be an Ankylosaur scute? thank you very much!

    Great condition.
  20. I see a lot of misunderstanding on what is being sold online at auctions and dealers sites. Some have it correct but most mix up the terminology. So here is Anky 101 aimed at Novice collectors and I will keep it simple. What you see sold in most markets are teeth from late Cretaceous North American locations mostly Montana, Wyoming and the Dakota's so I will focus on those areas. (Hell Creek, Lance, Two Medicine and Judith River Formations) Teeth from Canadian locations will have similar characteristics. There are two basic families of armored dinosaurs in these regions Ankylosauridae and Nodosauridae. Ankylosaurids are the brutes with big tail clubs. Nodosaurids have no clubs but are fierce looking with big spikes projecting from its sides. You don't want to meet up with either family. So when these teeth come up for sale most are very worn and it can get difficult to ID, so if possible avoid buying those. There is also a variation in the teeth with jaw position. Wear facets are also very common on these teeth. My photographs show complete teeth that have little wear so you can see what they typically should look like. Let me call them your generic teeth and are good representation of these families. There are multiple genus that you run into and the species is dependent on what formation you are in, see below with what is currently understood. Some have yet to be described to a species level due to lack of skeletal remains but teeth are plentiful. Differentiating teeth between the two families is quite easy. For Ankylosaurids crowns are small with long roots with two key characteristics, a bulbous base, see white arrow and a prominent central ridge on SOME species like Ankylosaurus in the Hell Creek others it covers the entire face of the crown. Other examples of North American Ankylosaurids Nodosaur Teeth: Are much larger, both taller and wider than Ankylosaurids, a shelf is visible below a pocket in the crown, no center ridge. Looks like a mit. Hell Creek Formation Two Medicine Fm Undescribed Nodosaur Judith River FM If you are interested in additional reading let me suggest Dinosaur Systematics by Ken Carpenter. Its also a good book describing theropod teeth. Our current understanding of species described: based on the revised analysis by Paul Penkalski, 2018. These views might not be share by some paleontologists but thats normal. Let me also say that with new discoveries and research some of this is subject to change.
