Sélacien34 Posted May 23, 2013 Share Posted May 23, 2013 I hope someone will know what kind it is. Origin: near Montpellier, Miocene, France. Kind of scyliorhinus ? Thank you for your answers Link to comment Share on other sites More sharing options...
zachj Posted May 23, 2013 Share Posted May 23, 2013 angel shark? one day i will find a tooth over 3 inches in good conditon haha. Link to comment Share on other sites More sharing options...
Al Dente Posted May 23, 2013 Share Posted May 23, 2013 The closest I can think of is Trigonognathus but I think the European ones are Eocene. The first tooth can't be angle shark because it is lacking the overhanging enamel apron. The second tooth does look like Squatina. Does it have an enamel apron?

siteseer Posted May 24, 2013 Share Posted May 24, 2013 Al Dente, It does look like Trigonognathus and the size seems right. It might be a new species but hard to say based on one tooth. The genus is otherwise poorly known in the fossil record - a Middle Eocene (Lutetian) form from France and the modern species known from the coast of Japan. Do you have Cappetta and Adnet (2001), which describes the Eocene species and reviews the dentition of the modern one? It's in French. There is an English translation on the Polyglot Paleontologist site: http://www.paleoglot.org/browse.cfm Scroll down to find the download for a pdf of the translation.

Sélacien34 Posted May 25, 2013 Author Share Posted May 25, 2013 (edited) I don't think that is squatina subserrata. I have looked at Cappetta's book about Loupian and i didn't find what it could be... Thank you very much for the publications, i will download that and will try to find something Inside. Here more photos about more of those teeth. I have put some S. subserrata to make the difference clear. I'm not a specialist but i see no type of tooth like this in the miocen of the South of France. there's a tranverse nutrient groove on the root in the middle of the root of the holaulacorhizous type, looks like a kind of scyliorhinus ? It also looks a bit like some teeth of squatina hassei from Cretaceous. Is that Young Squatina subserrata may have teeth like that ? Or maybe it's just Physodon fischeuri, i'm not sure because i have no complete views of this specie. What do you think ?

siteseer Posted May 26, 2013 Share Posted May 26, 2013 Hi Selacien34, I know about that translation because I'm the one who did it. I don't know with certainty but I believe the Polyglot Paleo site offers translations with the assumption that the people downloading them already have the originals. The article is: Cappetta, H. and S. Adnet. 2001. Decouverte du genre actuel Trigonognathus (Squaliformes: Etmopteridae) dans le Lutetien des Landes (sud-ouest de la France). Remarques sur la denture de l'espece actuelle Trigonognathus kabeyi. Palaontologische Zeitschrift 74(4):575-581. I don't have a pdf of this article but you should be able to find Henri Cappetta's email address. He would be interested in that tooth.

Sélacien34 Posted May 27, 2013 Author Share Posted May 27, 2013 (edited) Thank you very much for your answer. I may contact him but i have to be sure for that that those teeth are unknown. It could be possibly Physodon Fischeuri, i'm not sure because the only representation that i have about it is from capetta's thesis of 1970 and the teeth can be seen only from behind and in black and white... Do you know Physodon fischeuri ? It has became Rhizopriononsdon fischeuri. Would you have some pictures about this specie ? It could help.
