Hello! I recently got this tooth as a birthday present. It's a roughly .5" tyrannosaur tooth from the Hell Creek formation. I'm pretty confident this is a Tyrannosaurus tooth based on the very circular thick base, but I wanted to check in case it could possibly something else. Also, when I first looked at it I thought it was an anterior dentary tooth, but now I'm starting to think it may be a lateral dentary tooth. I was hoping someone could tell me roughly which position it would be in? I can provide any additional pictures. The tooth is very worn, and I circled both sets serrations so they w

Had another busy and enjoyable afternoon volunteering at the FLMNH vertebrate paleontology warehouse which was part of the reason why Tammy and I moved up to Gainesville. This afternoon started out with sorting the bones from non-bone for the last couple of bags of the > 1/4" chunky matrix pieces from sandbags collected at the Montbrook site in 2017. Now they can start screen-washing 2018...and then 2019...and maybe someday get caught-up to the present. In some of my first 1/4" matrix bags, sorting the complete bones (to be cataloged) from the scrappy broken bones, I had missed

*Just a note that this is a follow-up post to the VFOTM post that I wanted to share.* After reading a few posts here on the forum I decided I’d go to the NSR when I got the chance. I’d read it was good for beginners and the opportunity presented itself in April, 2020. I decided I’d make the trip and see what I could find. The first trip I hunted I found very little and walked a great deal until the very end of the day when I finally found two small mosasaur teeth. One of which was a Globidens sp. I was instantly hooked. Two weeks later, on my second ever fossil hunting trip I spott

This 215 m.y. old dentary was only 2 cm long, but it tells a big story in early mammalian evolution. https://phys.org/news/2020-10-tiny-jaw-greenland-complex-teeth.html

I've got five jaw fragments from the Kem Kem of which I think they are from crocodilians. Any ideas as to what genus or species these belong would be appriciated. 1. No idea what this jaw is from, but my best guess is some crocodilian. 2. I also don't know what this is but also probably some crocodilian. 3. This one has a hard layer of sediment covering it and it's missing the underside of the jaw. It looks a bit like the dented part of a Spinosaurus dentary but it's more likely also crocodilian. 4. Definitely crocodilian, has a typical croc texture (lots of dents). To me i

Any repair work on this Pterosaur jaw?
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
Recently i purchased this lower pterosaur jaw fragment (23cm in length) and i have been paying it off bit by bit (currently on hold). The seller claims absolutely no work has been done to it though it looks like there has been a repaired crack about one third down the jaw. I wanted to ask whether anyone can see if there has been any work done to it that isn't listed or that i haven't spotted. To me it looks good and looks mostly natural (except maybe the repaired crack). I don't have the fossil yet so i hope the pictures are enough. Thanks in advance. -
A partial left dentary (lower jaw) of a small mosasaur. On the side there is a large pathology visible on the bone surface.

So I got gobs of turtle stuff as many of us Floridians have and there were all kinds of these guys crawling and swimming around here. I was wondering if any of you have run across complete turtle/tortoise jaw/dentary's and might confirm these fragments might be. So here are 3 fragments that have interesting textures. All 3 have a gentle curve/arch/narrowing to them. 1) seems to have a porosity/pitting very similar to alligator or croc and I'm not sure if that immediately excludes it as part of a turtle jaw.
