  1. A 12-year-old found a 69 million-year-old dinosaur fossil while hiking with his dad By David Williams, CNN, October 16, 2020 Twelve-year old boy finds dinosaur fossil at Nature Conservancy of Canada Horseshoe Canyon site, October 15, 2020, Calgary, AB Yours, Paul H.
  2. Is it easy to find the size of the animal with a tooth? For example, i have a spinosaurid tooth from morroco 2.75 inch long (approx. 2 cm is root), a large mosasaur tooth about 2 inch, a Carcharodontosaurus 1.94 inch. My estimation: my spino tooth belong to an animal about 7-10 meters long if it is a of the large teeth on this spino mouth, for the carcha i think that came from the middle or the back of the jaw of an animal 5-8 meters long, and the mosasaur from a 7-8 meters long mosasaur, and is a very thick tooth.
  3. dinosaurs are lizards

    I am making a book showing evreyone that dinosauria is part of squamata. You will realize all of you are wrong when it comes to dinosaurs (thats how good it will be), I want to challenge pre concived notions and fill them with new ones. If you want to have a conversation with me that would be great!
  4. What dinosaur does this bone belong to?

    Morrison formation, Jurassic period, grand junction Colorado
  5. Yesterday I received received a PM from Rich @stats to see if I wanted to go collecting with him on Mazon Creek, but I told him that I had to pass since I was going to the zoo with my grandson AJ. Now, if I was just going with my wife to the zoo, I would have been on the creek right now collecting- It was a great day, with great weather and there is no better way to spend a Sunday that with my son and his family. Here are a bunch of pictures of the exhibits, it was great for everyone. Here is a picture of me and AJ. And now a picture of my son Alex and wife Izzy + AJ. Now on with the other pics.
  6. Came across this tooth labeled as an abelisaurus belonging to chinanisaurus barbaricus from the Maastrichtian supposedly found in the phosphate mines of the Ouled Abdoun basin. Looks pretty thick to be abelisaurus and comparable to an extent to some carcharodontosaurus teeth. Is there a way tell the difference or will there need to be more specifics involved.

  10. Dinosaurs

    Last night I was flipping through Amazon Prime and found a Dinosaur documentary that I had not seen yet... https://www.amazon.com/Dinosaurs-Francesco-Invernizzi/dp/B07V3X6L14 ...part way through I recognized one of the paleontologists as our very own, @jpc! I love a good Dinosaur flick and this one was worth watching...enjoy.

  12. What About Birds ?

    I dont mean to sound so ignorant but ive been watching some dino type shows on TV and I realized a question. On one of the shows a guy was pointing out the KT boundry. Then he goes on to say that below this boundry dinosaurs can be found and that above this bondry no dinosaurs can be found. On another show they were talking about how birds are decendants of the dinosaurs. So, my question is, How can birds have evovled from something that went extinct 65 million years ago? I know there must be a simple answer,,,,, but what the heck is it? RB
  13. I've noticed while my library of fossil books is very small, I have not come across a book about dinosaur fossils that is picture heavy with photographs of dinosaur fossils compared to everything else. Would anyone be able to recommend any picture heavy books that focus on dinosaur fossils (teeth, bones, skeletons, etc) that would make for a good flip through?
  14. Unidentified Dino bone

    Hi, I was wondering if anyone could identify this for me? it was found in the lance formation, and is just over an inch long.
  15. MusicnFossils’ Living Room

    Hello all, I was waiting a while to show my ever growing collection until I finally got this new shelf. I wanted to paint it to look similar to my other shelf, install these neat colour changing lights, organize things and move everything...then take photos! I had stored everything in my bedroom for a while but now everything is front & center for visitors. As has has been made obvious by my many ID posts and couple threads in the, “fossil hunting trips” section, I live in a fossil rich area have access to much land to collect from frequently, so I will use this thread for updates with future finds. I’m very proud to say that much of my collection, mostly the dinosaur stuff, has been found by me rather than been bought, though there is a lot of money invested here. If you would like more or better pictures, info or would like to help me ID anything in this collection that I’m unsure about (I’m severely lacking in physical labels at the moment) don’t hesitate to ask.

  17. My “Mesozoic Park”

    Well, I figured that I should start a member’s collection. Sorry for my absence, I was busy with college classes. I did great this semester, and I even won a student leadership award! With that being said, I’m gonna start my collection off with a piece that I acquired for my birthday! My 22nd Birthday is tomorrow (June 14th), and I was strapped for money. My father and grandmother chipped in, and helped me acquire this chromium woodworthia piece from a local rock shop that I frequent! It’s from Arizona, and it only cost $60 USD! I’ll try to be active here whenever I can, as I am exhausted from this semester of college (having to abruptly switch to an online format due to COVID-19). I’ll have to link other threads of my fossils and post pictures of my previous additions to my collection to this thread whenever I have the time!

  19. Took A Long Hike Today

    I wanted to try some new spots that are closer to home, so a family here was nice enough to take me out to their land near Dinosaur Provincial Park and allow me to surface collect. I only kept two things (wasted a good portion of the day searching for tyrannosaur teeth to no avail) but I did find some neat stuff so I thought I’d share. Please excuse the circling and the caption, those were for Instagram. Nice & green this time of year. Won’t look like that for long. Heres something I found a few times today; random pits of petrified wood just shattered. Here’s a good 10 inch chunk that I kept. More petrified wood. Dino bones. Most of them were broken and difficult to tell what they were, as the dinosaur park area bones usually are. Please excuse the circling. It was for Instagram. This was the largest bone I seen today, was over 2 feet long most likely but it was at an awkward place so I didn’t climb any higher to get close. Excuse the caption. This one was fairly large as well. This one I kept because it was one of the only good condition bones that wouldn’t require excavation. Hadrosaur toe bone. (thanks jpc for the help)
  20. Raptor tooth

    If a site write "raptor" tooth, in what species is more possible to belong the tooth? (from morocco)
  21. I have a question, have any dinosaurs been found in Kothapalli, Maharashtra, India?
  22. Hey guys hope everyone is staying safe during this time of uncertainty. Me and friend have created a fossil Instagram page to share our collection and have a platform to show it off while we are all in lockdown. Not just are we going to be sharing fossils and hopefully when this is all over showing field work we also have got a few friends who are currently publishing work during there PhD’s all across the world. Having discussed with them earlier we are gonna be promoting paper and stuff when released and sharing links to where you can find them as well as a little blurb each time they get one publish- here’s the link to the first i hope to see you all on our page! kaiser

  24. Hello, I've put teeth here for Id a couple of times and always received a satisfactory answer. I hope you can help me this time too. It is about this Ceratopsidae tooth from the Niobrara Formationn (Wyoming). Unfortunately no fossils of this group are known from this formation and I therefore wanted to ask you if you have any idea what species of dinosaurs the tooth could belong to. The tooth is 1,5cm in size. I hope if you can help me with this! Best regards from Germany!
  25. Dinosaur fossils from the mid Jurassic are generally rare but the Isle of Skye in Scotland has revealed fossils sites preserving around 50 footprints on ancient coastal mudflats. The footprints suggest that Stegosaurs and possible ancient cousins of duck billed dinosaurs were living in the Isle of Skye around 170mya along with large Sauropods & Carnivores, suggesting a high diversity of dinosaurs from the mid Jurassic in Scotland. https://www.sciencedaily.com/releases/2020/03/200311140536.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ffossils_ruins%2Fpaleontology+(Paleontology+News+--+ScienceDaily) The Journal article is listed below and is open access https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0229640 1. dePolo PE, Brusatte SL, Challands TJ, Foffa D, Wilkinson M, Clark NDL, et al.
