Bails Posted August 14, 2020 Share Posted August 14, 2020 Hey all, I found these 3 teeth and vertebrae on a hunt this week and was hoping to get an ID on them since I do not recognize them. Any help would be greatly appreciated! If a need to post any other pictures please let me know! Link to comment Share on other sites More sharing options...

ThePhysicist Posted August 14, 2020 Share Posted August 14, 2020 For future posts, it's also helpful to tell us where you found them. 1. Angustidens 2. Mako 3. Mako 4. Not a vertebra, but a pufferfish/porcupine fish mouthplate Shark/fish vertebrae are typically cylindrical with conical depressions in each of the circular faces, and holes (called "foramina") on the other, lateral surface. I'll let others who are more familiar with these teeth be more specific on 2 and 3.

ThePhysicist Posted August 14, 2020 Share Posted August 14, 2020 Here are some shark vertebrae (from a post on the forum) "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...
Bails Posted August 14, 2020 Author Share Posted August 14, 2020 Do you think that the chipped pieces on the Angustidens happened from the shark itself or is it too hard to tell? Interesting how preserved the serrated edges are except for those couple of spots. Link to comment Share on other sites More sharing options...
PrehistoricWonders Posted August 14, 2020 Share Posted August 14, 2020 I’d say the damage on the first two are feeding damage from the shark eating! Good finds, I LOVE the colors on the angustiden!!!!! Link to comment Share on other sites More sharing options...
Praefectus Posted August 14, 2020 Share Posted August 14, 2020 1 - Otodus angustidens 2 - Anotodus retroflexus 3 - Also retroflexus??? Mind if I phone a friend @WhodamanHD 4 - Pufferfish mouthplate. Link to comment Share on other sites More sharing options...
Bails Posted August 14, 2020 Author Share Posted August 14, 2020 Thanks so much @Praefectus! Do you know where I can find some more info on Anotodus Retroflexus? I didn't see much on a quick google search. Thanks, Bailey Link to comment Share on other sites More sharing options...

I didn't see much on a quick google search. Thanks, Bailey Try looking under Isurus retroflexus. A debate exists over whether it should be classified under the genus Isurus or Anotodus. Here is a link to the elasmo page. http://www.elasmo.com/frameMe.html?file=heim/leecreek/lc-isurus.html&menu=bin/menu_topics-alt.html Here are 3 TFF topics that discuss them. 1 Link to comment Share on other sites More sharing options...

Mind if I phone a friend @WhodamanHD Tough call, but I think it’s actually Parotodus benedeni, which is an even more awesome tooth in my opinion. I have also decided to lean towards to retroflexus being Isurus if not flat out conspecific with I. paucus, but that is simply my opinion (which changes frequently.) 2 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

I wasn't even considering benedeni. Now that you mention it, it does look like a match. Thanks for the help. Link to comment Share on other sites More sharing options...

Bails Posted August 14, 2020 Author Share Posted August 14, 2020 Thanks @WhodamanHD!! New to all of this, but I have seen people talk about a Benedini and they seem a bit rarer. Any Info on them or explanation for that? Thanks so much for helping us new collectors out! Link to comment Share on other sites More sharing options...

P. benedeni was a pelagic shark, meaning it spent much of its time in the open ocean. Most marine fossil deposits on land today are from shallower deposits. Due to this, it is usually rather rare. However, for whatever reason it seems to be more common in South Carolina’s Oligocene than in the Miocene elsewhere, for example some never find one in Maryland after a lifetime of Fossil hunting. Let me know if you have any further questions, I’m happy to help “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
