I believe I have made quite well with collecting Moroccan mosasaurs, so I wish to set my eyes for new goals. And first US mosasaur material is already heading its way. I have been hoping to learn more about American mosasaurs in general and also basic tooth characteristic of more common species. Only one Im relatively familiar with is Tylosaurus proriger. With Platecarpus tympaniticus only by few articles. I managed to find information about most formations where material seem to come from, but not Ozan fm. What species were present besides Tylosaurus proriger? Thanks for replies.

New mosasaur species named from the Pierre Shale of North Dakota: Jormungandr walhallaensis
pachy-pleuro-whatnot-odon posted a topic in Fossil News
A new mosasaur, related to the genus Clidastes, has been described from the Middle Campanian Pembina Member of the Pierre Shale Formation of North Dakota near the town of Walhalla and has been given the undeniably cool name of Jormungandr walhallaensis, after the world serpent of Norse mythology! Zietlow, Boyd and Van Vranken, 2023. Jormungandr walhallaensis: a new mosasaurine (Squamata: Mosasauroidae) from the Pierre Shale Formation (Pembina Member: Middle Campanian) of North Dakota. -

*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 spotted the exposed section of the tip of the dentary which was only an inch above the marl, and kept walking thinking that it was just wood sticking out of the riverbed. Keep in mind it was after a two hour drive and seven hour hike, I hadn’t read much about fossils, and had no idea about how to properly collect a more complete vertebrate. I continued walking and my exhausted heat addled brain finally processed that the chances of there being an old black piece of wood stuck in the bottom of the riverbed wasn’t that likely. So I walked a few yards back and was lucky enough to find it. Beginners luck! I didn’t take a picture of it until I exposed the first tooth. First picture though is just the anatomy of my find as I understand it. This was the first picture I did take of the right dentary. The NSR can rise pretty fast, especially when it’s raining out west and it was slowly rising so my find started going under water. I was stuck between trying to get it exposed and out of the ground in as best shape as possible and risking it going under which I didn’t know how would effect it. To top it all off the only tool I had was a screwdriver. Here is the dentary nearly exposed. And exposed. I dug a little channel that diverted some of the water away, but it was only effective for a few minutes. And here’s the shape it left in the river bottom. By the time I had the find out of the ground the water level was well over the site and the sun was going down. I decided I'd go back as soon as possible to see if I could find any more.

Hi all, I have a set of three lovely reptilian teeth from Barbour and Russell Counties of Alabama that I need help identifying. First up, the large mosasaur tooth. The size and general shape of this points to Tylosaurus, Second, the smaller mosasaur tooth. The size and shape points either to Platecarpus or Clidastes propython. I can't decide. Third, the croc. As far as I know, Deinosuchus and Bottosaurus are the only crocs from this area. The tooth looks like Bottosaurus to me. I'm unfamiliar with teeth from this locality, so I'd appreciate any help in getting them identified.
