  1. 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?
  2. 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.
  3. 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.
  4. 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 ?
  5. 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
  6. 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?
  7. 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
  8. 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.
  9. 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"
  10. 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.
  11. 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!
  12. 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.
  15. 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 Ankylosaurids and Nodosaurids. 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, like your in-laws. So when these teeth come up for sale most are very worn and it can get difficult to ID. There is also a variation in the jaw. Wear facets are 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 the genus. There are three typical genus that you run into Ankylosaurus, Euoplocephlaus and Edmontonia and the species are dependent on what formation you are in. Some have yet to be described to a species level due to lack of skeletal remains but teeth are plentiful. There also no guarantee that there are not additional Nodosaurids or Ankylosaurids in these formations so identification below a family level can be problematic. For Ankylosaurids: Ankylosaurus , Euoplocephlaus For Nodosaurids : Edmontonia Ankylosaurus Teeth: There are two distinguishing features to identify these teeth. The arrow on second picture points to a bulbous base and the straight lines point to a prominent central ridge. Euoplocephlaus Teeth: These are typically smaller teeth in the 3-5 mm height range. They have no shelf at the base of the crown and the ridges and grooves have no regular pattern to the edge of the cusp. The second photo was borrowed from the Paleo Direct site was a good photo tooth Edmontonia Teeth: These teeth are bigger than the others, have a clear shelf and no additional ornamentation or ridges on their face. I show two different teeth and the arrow on the last photo shows the shelf. If you are interested in additional reading let me suggest Dinosaur Systematics by Ken Carpenter. Its also a good book describing theropod teeth. Edit: the validation of the Nodosaur : Denversaurus schlessmani in 2015 makes diagnosing Nodosaurids in the Hell Creek or Lance Formations impossible since there is nothing diagnostic on the crowns. They should be identified as Nodosaurid indet.
