Any pterosaur experts able to ID an old Mongolian tooth? I've been looking into it and believe it could be Noripterus, going by the description of Noripterus been cone-shaped teeth and, the fish-based diet of Noripterus also fits conical teeth. It's an old collection tooth and seller doesn't have the formation, unfortunately, other than it being early cretaceous. I believe it might be from Tsagaantsav Formation which is one of the few formations I could find which fits the early Cretaceous age and has pterosaur remains found. Now, I personally haven't seen any teeth which resemble this one. The closest is Lyme Regis ichthyosaur, but I don't think Ichthyosaur has been found in Mongolia, I don't think it's a marine formation and there are no striations on the tooth. The base doesn't have a great photo, but it is oval in shape--matching the one pic I could find of Noripterus jaw. I haven't heard anything back from a couple I've emailed it too, except for one paleontologist who didn't recognise it. It's a very small tooth. 12mm in length. If someone is able to take a look, that would be great.

Hi all. A new type of dinosaur egg just went online recently, and is being sold at a rather startling price of multiple thousands. Question is, are these genuine dinosaur eggs? If so, or if not, what could they be? They come from Negmegt Valley, Bugin tsav. EDIT: These are 4.5 - 5cm each.
