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!

Anomotodon Posted October 25, 2020 Share Posted October 25, 2020 I believe this is Cantioscyllium or some other Ginglymostomatid (nurse shark) 1 Quote Link to post Share on other sites

PaleoNoel Posted October 25, 2020 Share Posted October 25, 2020 The potential turtle looks like turtle to me. 1 Quote Link to post Share on other sites
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 Quote Link to post Share on other sites
