fifbrindacier Posted March 21, 2021 Share Posted March 21, 2021 (edited) Hi, I found that tooth of 3 centimeters long in a Serravalian layer. I believe this is an odontaspis, what is your opinion? @Darktooth@Al Dente @Troodon@Harry Pristis?

Darktooth Posted March 21, 2021 Share Posted March 21, 2021 Nice Tooth Sophie! Unfortunately I do not have enough experience with this species to give an accurate ID. This is a lovely matrix specimen for sure. Congratulations on the find! 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Harry Pristis Posted March 21, 2021 Share Posted March 21, 2021 If I found your tooth here in Florida, I would call it Odontaspis. Nice example! 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...

Coco Posted March 21, 2021 Share Posted March 21, 2021 Hi, Since Serravalien is Miocene, Ondontaspis is a very old name for French teeth. It has been changed to Synodontaspis to be Carcharias for 10 or 20 years. Your very beautiful tooth is probably a Carcharias acutissima.

Al Dente Posted March 21, 2021 Share Posted March 21, 2021 Maybe Carcharias or Araloselachus. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted March 21, 2021 Share Posted March 21, 2021 Gorgeous! It looks like Carcharias (sometimes ones of this age are called Araloselachus). Recent mtDNA analysis has suggested Odontaspis and Carcharias might not actually be closely related, the tooth shape similarity being convergent “...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...
Ludwigia Posted March 21, 2021 Share Posted March 21, 2021 Araloselachus cuspidatus maybe? Nice tooth anyway. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

sharkdoctor Posted March 24, 2021 Share Posted March 24, 2021 Sophie, that is a gorgeous tooth! Congrats on the find. We don't have Miocene Odontaspis in this area (according to Kent's Calvert Volume chapter). However, elasmo.com has a nice summary of Odontaspis that I've included below: "Diagnostic tooth details included: Narrow sharp primary cusps with multiple slender lateral cusplets, Broadly splayed, U-shaped, narrow (when viewed labially) deep (when viewed laterally) root lobes, Incomplete (basally) cutting-edge. Cappetta (1987: 88) included four species known from the fossil record: O. aculeatus (CAPPETTA & CASE, 1975) [Upper Campanian of New Jersey], O. ferox [Lower Pliocene of Italy], O. speyeri (DARTEVELLE & CASIER, 1943) [Palaeocene of Africa] and O. winkleri LERICHE, 1905 [Lower - Middle Eocene of the Anglo-Franco-Belgian basin and Eocene of Maryland]." Based on that summary, it seems that Odontaspis is only known in your area from the Middle Eocene and that the tooth doesn't really conform to the description of Odontaspis. I'm with @WhodamanHD, you'll want to consider another genus for this beauty. 1 Link to comment Share on other sites More sharing options...
fifbrindacier Posted March 25, 2021 Author Share Posted March 25, 2021 Thank you man, i'll wait for whodamanHD's opinion. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."
