  1. Hadrosaur jaw fragments

    These are two Hadrosaurus jaw fragments I’ve had for awhile. As far as I know they are from the Hell Creek formation of Montana. I think they might be Edmontosaurus but I really can’t tell. The fragment exhibiting tooth channels is about 8 inches in length. The other fragment or chunk exhibits many broken teeth and is about 4 inches in length. @Troodon @jpc might like to have a look?
  2. Fossilized Vertebra identification

    Hello, I am hoping someone can help identify this fossilized vertebrae that was found along the Missouri River near St. Louis, MO. It is 2" across.
  3. Hadrosaur tooth variation?

    Howdy all I’m wondering if there is any variation in the teeth between different hadrosaur species? In the guide to common vertebrate fossils of Alberta there is a diagram that portrays a supposed Corythosaurus tooth and that some other tooth diagrams do not represent Corythosaurus. There’s a bit of a difference between the diagrams, but I’m unsure if it warrants identification to a genus level. I took a look at my hadrosaur teeth and noticed there is a difference between these two. The one on the right is wider and has a more prominent central carina. Could this be taxonomic variation, or is it just individual variation? Any help is appreciated, thanks.
  4. Hello all. A decade ago, before I started keeping proper track of the specimens I own, I purchased a partial femur specimen (for context, it was fairly cheap, less than $150 I think). Anyway, I 'think' that it was from a Hadrosaur, but I don't think the seller knew for sure -- and I know for sure that I don't know for sure! Anyway, I don't recall the formation (I'm going to guess Judith River, but that's based on very little). Any, if anyone is able to readily identify/confirm that the partial femur is from a hadrosaur, or from something else, I'd deeply appreciate it. The specimen is highly mineralized and heavy; please see photos. Thanks!
  5. Ajnabia dinosaur jaw?

    Hello! I see this jaw with teeth from Ouled Abdoun Basin (Morocco). I read about the new Ajnabia descovered this year. What do you think? Real dinosaur or only a fish? Thank you so much.
  6. Montana Hadrosaur Bone?

    Greetings Found this section of Dino bone in a local antique shop. It was from an estate of a man who found it and a few others in Montana in the 1950s. Thought it was cool and it was listed as a Hadrosaur bone. Some great colours. I have included end shots to show the marrow in cross-section. I know there is not much to work with but would anyone know from what bone this section would be from? It is a long shot but ... it is worth a try. Best Regards Rob
  7. Possible skull of Hadrosauriea genus

    Hello, I am in possession of a dino skull that I believe to be of the genus Hadrosauriea. This skull was collected by my grandfather in the 40's in Platte Valley, WY near Saratoga. Also, for more questions or photos, I'll be happy to accommodate. Thanks for the help! RockhoundBrycer
  8. I am thinking about buying a Hadrosaur center toe fossil. Before I buy the fossil I am wondering if they are real or fake and how I can tell.
  9. Hi My son has recently been given this ‘fossil’ by a relative. They bought it about 20 years or so ago from an antique shop in Hong Kong. They were sold it as a hadrosaur egg but we have no idea really if it is or not. I’m inclined to think not simply because I’m always suspicious
  10. Hadrosaur Phalanx?

    I'm wondering what this is. My best (non-expert) guess is that it is a toe bone of some sort. It's about a couple inches (appx. 5cm) in length & equally wide. It resembles some smaller Hadrosaur phalanges I've come across, but that is just a guess. To the best of my knowledge, it hails from Hell Creek. Any thoughts? Thanks in advance!
  11. Two eggs--if someone can take a look and let me know what you think, that would be great. They are Hadrosaur eggs from China. From the Nanxiong Formation in Guangdong Province. Seller says no repairs or restoration. And adds that the first egg is more complete than the 2nd. Egg 1: 10cm x 6CM Egg 2: 11cm x 7 cm Now, does the slight difference in size mean they could be from different species, or can dino eggs from same species sometimes be slightly smaller? Or could the size difference just be due to fossilisation--one getting a bit more squashed and elongated than the other? Now, with these--I assume the brown stuff is sand and matrix covering the shell---that wouldn't be a cause for concern and be hiding something shady?
  12. A new study got published on some new hadrosaur material from Spain. https://www.sciencedirect.com/science/article/abs/pii/S0195667120303645?via%3Dihub Abstract It's paywalled sadly.
  13. Hey! These are just a few of the bones I found recently which were all found near each other in horseshoe canyon AB. I found what I believe to be albertosaurus teeth and a piece of a hadrosaur jaw as well with them which makes me assume they are from one of those two species. However, I need help identifying which species each one might be from and what part of the dinosaur they are. If you need measurements I'm happy to post pics next to a ruler!
  14. Hi, I recently bought these Dino eggs.I would appreciate any opinions on these as far as being real or fake?Quality etc.Thanks
  15. Tooth Id

    Hey! Both of these teeth were found in the horseshoe canyon in the same place. I was thinking Albertosaurus but I don't know(They are serrated if you couldn't tell from the photos). Any ideas? (sorry for the low quality images)
  16. Unfortunaterly, there's not much information--the seller doesn't usually deal with dinosaur fossils and has had it instorage for over a decade, so the only info available is that it's a Hadrosaur egg, from China and cretaceous with shell loss to one side. No more specific as to location/formation. Length = 17.5 cm Weight = 4.3 kg So, what do people think about it? Now, I was wondering, could the base be hiding some damage/a hole? The base looks a bit off to me, like it's been added---is it a common bit of fakery to make a partial egg look complete by applying a base to them and could that be the case here? Thanks for any help and opinions.

  20. Hadrosaur bone

    Hi again everyone Here is Bone likely from Hadrosaur (as far as seller told me) from Lance creek formation . It look like to be a partial section of Metatarsal bone ? what do you think guy??? Thank you in advance !
  21. I found a bunch of these teeth on the Judith River Formation yesterday and not sure of the identification. Based on google searches they appear to be (from left to right) triceratops, ankylosaurus, and Hadrosaur. The one on the left is about 3/4" as a reference. Any direction would be greatly appreciated.
  22. I found these toe bones yesterday in the Judith River Formation near the Canadian border. I have found several bones like these but not completely sure of the identification to give them. They appear hadrosaur or triceratops like based on a google search of other similar bones. Let me know if you can identify them.
  23. These pieces were both found in the horseshoe canyon cretaceous formation in Alberta. There were multiple hadrosaur teeth and bones nearby, so that could be a starting point. Could anybody help me with an ID?
  24. Edmontosaurus annectens

    From the album Dinosaurs

    Hadrosaurs evolved very interesting teeth and complex mastication. Read "Complex Dental Structure and Wear Biomechanics in Hadrosaurid Dinosaurs:" https://science.sciencemag.org/content/338/6103/98
