Bradley Flynn Posted September 15, 2020 Share Posted September 15, 2020 Visited a friend this weekend who gave me some nice fossils. I know where the black teeth come from and I'm guessing that the lighter teeth are from Morocco. The circled tooth I'm unsure about, any ideas?

ThePhysicist Posted September 15, 2020 Share Posted September 15, 2020 Indeed the lighter ones are Moroccan. Squalicorax pristodontus (serrated) and Serratolamna sp. The dark ones are makos. The tooth circled is mosasaur. The "ribbed ring" is a piece of ammonite. 1 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...
Bradley Flynn Posted September 15, 2020 Author Share Posted September 15, 2020 I'm thinking that the ammonite piece is dactylioceras sp. Had an idea it might be mosasaur, but had to make sure. Thanks for all your help Link to comment Share on other sites More sharing options...

I agree with ThePhysicist on all the other IDs. 1 Link to comment Share on other sites More sharing options...
