Bails Posted December 15, 2020 Share Posted December 15, 2020 Hey All, I found this tooth on an early afternoon hunt today in Charleston, SC. I wanted to see if anyone could confirm if it is a Carcharocles angustiden or if it could possibly be a Carcharocles chubutensis. Reason I ask is the cusps on the side seem less pronounced then other Angy’s I have found and seen. They don’t appear to have broken off. My initial thought is that it is an Angy, but wanted to doubles check. Happy to post additional pics if needed. Thanks in advance! 1 Link to comment Share on other sites More sharing options...
Macrophyseter Posted December 15, 2020 Share Posted December 15, 2020 The integration of what appears to be the cusps with the main crown makes this something of a chubutensis or juvenile megalodon IMO. 1 If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Bails Posted December 15, 2020 Author Share Posted December 15, 2020 @WhodamanHD @Al Dente @BellamyBlake @Praefectus Let me know if you have any insight on this one as well! Thanks! And thanks @Macrophyseter! The more I have examined the more I agree with your comment above. Link to comment Share on other sites More sharing options...

Miocene_Mason Posted December 16, 2020 Share Posted December 16, 2020 Definitely not an angustidens, probably a late chub, early meg.

Bails Posted December 16, 2020 Author Share Posted December 16, 2020 @WhodamanHD yeah that makes sense and thanks! I realized it looked more like a meg opposed to angustidens the more I examined after the post. I also read juvenile megs can retain ancestral traits such as lateral cusps which I wasn’t aware of. Thanks for your insight! The coloring on this one is great. Here is a pic after it dried out. Link to comment Share on other sites More sharing options...
BellamyBlake Posted December 17, 2020 Share Posted December 17, 2020 Chub/Meg imo! Link to comment Share on other sites More sharing options...
Bails Posted January 22, 2021 Author Share Posted January 22, 2021 Found this guy in the same exact spot yesterday! Pretty sure that one is a C. angustiden. Would y’all agree? Link to comment Share on other sites More sharing options...
Boesse Posted January 23, 2021 Share Posted January 23, 2021 Agreed with C. chubutensis or juvenile (not even necessarily early) C. megalodon - and for what it's worth, seaward of downtown, bona fide Oligocene fossils become quite a bit less common and instead Miocene and Pliocene marine verts are more common, with Pliocene fossils being the predominant finds along the coast and Miocene material along the harbor.

Bails Posted January 23, 2021 Author Share Posted January 23, 2021 @Boesse so you think the most recent one I found is a early/juvenile Meg or Chub? I definitely think the first one I found is an early/juvenile Meg or Chub. For what it’s worth it was found along the harbor. Thanks for your help!

Bails Posted January 23, 2021 Author Share Posted January 23, 2021 Also found this one in the same location yesterday. Is this an Angustiden? It’s so tough for me to differentiate auriculatus, angustiden, and chubutensis. 1 Link to comment Share on other sites More sharing options...
BellamyBlake Posted January 23, 2021 Share Posted January 23, 2021 I'd say your second one is Angustidens, while the third one almost certainly appears to be Angustidens. Link to comment Share on other sites More sharing options...
Bails Posted January 23, 2021 Author Share Posted January 23, 2021 My thought as well. Thanks @BellamyBlake Link to comment Share on other sites More sharing options...
Boesse Posted January 23, 2021 Share Posted January 23, 2021 As far as C. angustidens is concerned, there's quite a bit of variation. The last specimen has more of a notch between the cusplet and crown - typical for about 2/3 of specimens from the Chandler Bridge Formation. Perhaps 1 in 10 or so look like the C. chubutensis posted originally - but cannot be, since it is Oligocene, and therefore C. angustidens, whereas C. chubutensis is an early Miocene chronospecies. So, the age is somewhat more important than the anatomy, but the age is virtually impossible to know for many of these ex situ finds made along lowcountry waterways. 1 Link to comment Share on other sites More sharing options...
Shellseeker Posted January 23, 2021 Share Posted January 23, 2021 I always loved this one... and in looking for an ID, I came to realize that there are no Rics, Chubs or Angys in the Peace River. In addition to the cusps, I have always liked the "rawness" of this juvenile Meg. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Bails Posted January 23, 2021 Author Share Posted January 23, 2021 @Shellseeker awesome tooth! And yeah it’s tough in Charleston, SC because there are Rics, Chubs, and Angys and as @Boesse pointed out it’s very hard to tell age from these teeth that wash ashore from the Charleston Harbor.
