Meganeura Posted July 16, 2022 Share Posted July 16, 2022 Finally back from the creek and had some more ID’s I’d like to ask about! Mostly teeth, and one bone. 1+2) Thresher shark teeth? Never seen this type of shark tooth before. 3) Thinking this is Carcharhinus sp. and is a just posterior tooth, but I’m not sure. It is serrated. 4) Dolphin tooth - 99% sure on this one but wanted to confirm 5) Rhino tooth fragment? Note the vertical HS bands. 6) Toe/finger bone? 1+2) Thresher Shark? 3) Not sure - Carcharhinus sp? Has serrations though the pic doesn’t show em too well 4) Dolphin tooth? 5) Rhino tooth? @Shellseeker there’s vertical HSBs 6) Toe bone? 1 Fossils? I dig it.

ThePhysicist Posted July 16, 2022 Share Posted July 16, 2022 I agree 1,2 are threshers! Congrats! 3. is actually a tiger-like shark, Physogaleus ?contortus (not as familiar with the PR fauna so could be other species). 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...
Done Drillin Posted July 16, 2022 Share Posted July 16, 2022 Proboscidean enamel will show the striations you are seeing and is not the same as the vertical Hunter-Shreager bands being discussed in relation to the rhino teeth 1 1 Link to comment Share on other sites More sharing options...

Crazy, never found a thresher before today and I've been hunting for months - and I find 2 in one day. 3 - Interesting! I can see that being a tiger, just broken in exactly the right spots to obscure the usual tell-tale features. I thought the shape of the blade was weird for a Carcharhinus sp. Fossils? I dig it.

Filing that piece of knowledge away for now then, it's my first piece of Mastodon enamel so that's neat. All the other pieces I've found have been the root. Fossils? I dig it.

Fin Lover Posted July 17, 2022 Share Posted July 17, 2022 Your first 2 threshers and your first mastodon enamel...I think you can consider this trip a win. Just not for the shovel. 2 Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

Meganeura Posted July 20, 2022 Author Share Posted July 20, 2022 @Harry Pristis do you know what #6 here is? It seems similar to a phalanx/toe bone but I’m terrible with bones Fossils? I dig it. Link to comment Share on other sites More sharing options...

Thank you! I'll grab more pics when I'm home in a couple hours! Also looking at pics online, that appears to be a dead-on ID! Edited July 20, 2022 by Meganeura Fossils? I dig it.

Harry Pristis Posted July 20, 2022 Share Posted July 20, 2022 Not armadillo, I think. I don't know what medial phalanx it is, but I'd investigate bobcat. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
