JamieLynn Posted October 25, 2020 Share Posted October 25, 2020 Hello all! Sorting through some new Cretaceous Post Oak Creek matrix and have a few questions on what some of these might be. Thanks for any help! First is this round tooth....could it be croc? It doesn't have any striations, which I think croc would, but it is perfectly round so not a worn shark blade, I think. Anyways, any suggestions would be appreciated! 1. Tooth? 5 mm 2. This little piece...may not be identifiable as anything, but the surface texture is just interesting. 2mm other side 3. Possibly a denticle? Or tooth? I've found lots of sawfish teeth but this one doesn't seem to match anything else. 2mm other side 4. is this turtle? 1.5 cm 6, And lastly....this "claw" thingie. . 2 mm Thanks for looking! www.fossil-quest.com Link to comment Share on other sites More sharing options...
Anomotodon Posted October 25, 2020 Share Posted October 25, 2020 I believe this is Cantioscyllium or some other Ginglymostomatid (nurse shark) 1 The Tooth Fairy Link to comment Share on other sites More sharing options...

PaleoNoel Posted October 25, 2020 Share Posted October 25, 2020 The potential turtle looks like turtle to me. 1 Link to comment Share on other sites More sharing options...
ThePhysicist Posted October 25, 2020 Share Posted October 25, 2020 1. Probably fish... very unlikely for there to be croc in POC as it was an open ocean environment 2. Ptychodus. Compare: 3. agree with nurse shark 4. ya probably turtle 5. no idea 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...
