Had an idea a while back to try and make a replica maxillary cast of a tyrannosaur and set some of my real teeth I’ve collected from the JRF in it. This was attempt one - took me about an hour. Wanted to see if it was worth putting more effort into it. Next step would be getting someone much smarter than me to help identify some of my teeth so they can be in the correct area of the mouth. I’ve got about 40 to choose from. For now, it was just to get an idea.

I'll start with the jrf vertebrae which I believe to be a hadrosaur cervical wondering if it is possible to narrow it down to a species if possible? And again anyone who is taking the time to look over these I thank you very much in advance.

My three year old was playing with a box of random Dino bones this morning and he handed me this one - which I hadn’t really paid attention to before. It seems like they’re vessel grooves on the smooth surfaces? I know it’s tough to see the symmetry on my pics, and I know it’s pretty chunkosaurus, but I didn’t know with the unique convex and concave surfaces including the unique surface texture if it was at all identifiable. Unique shape. Frill piece? Unidentifiable? judith river formation of northern Montana - milk river thanks folks

Sorry about my not sweet picture skills. found Judith river formation of Montana - milk river. obviously a chunk of jaw, but we usually just find little croc jaws. This one is bigger, and the sockets just seemed theropod to me right off the bat. Grabbed a couple tyrannosaur teeth from my daughters display in her room and they fit like a glove. Super scientific, I know - but thoughts? thansk!

Hello all! I have acquired a very nice juvenile tyrannosaurid tooth from the Judith River Formation. I am fully aware that teeth from there are very difficult to be assigned a specie, but I was wondering if it could be narrowed down a little. Last time @Troodon was able to give me awesome info and help. The tooth is a premax tooth and is 1,7cm in length. I have a serration count for both distal and mesial sides: hard to tell for sure but it looks like 3/mm for the distal 4/mm for the mesial Thank you
