Max-fossils Posted February 19, 2017 Share Posted February 19, 2017 Hi, Here is a very weird sharktooth from Hoevenen (BE) --> Miocene. I can't find anything that looks similar to it, therefore I'd like your help on this one. Note that the tip is a bit broken off. Also, does anyone know a good guide that could be used to IDing sharkteeth? Best regards, Max Max Derème "I feel an echo of the lightning each time I find a fossil.

gigantoraptor Posted February 19, 2017 Share Posted February 19, 2017 Maybe it is a brachycarcharias sp. But I am not an expert. So lets wait until there are some other answers Link to comment Share on other sites More sharing options...
Al Dente Posted February 19, 2017 Share Posted February 19, 2017 It looks like Lamna nasus. Link to comment Share on other sites More sharing options...

Thanks for the help, but I really don't agree with that guess... I found this topic, I think it could help: What do you think?

Troodon Posted February 19, 2017 Share Posted February 19, 2017 Looks like a Lamna tooth to me Check this site for Belgium teeth http://www.belgiansharkteeth.be OR the elasmo.com site for most other material Link to comment Share on other sites More sharing options...

Angie Posted February 19, 2017 Share Posted February 19, 2017 I agree with Al Dente, it does look like a Lamna nasus, compare it with the ones on this https://english.fossiel.net/id_system/fossil_id_search.php?zoek=2781-0006 and on this https://english.fossiel.net/id_system/fossil_id_search.php?zoek=558-0015 picture. The tooth in the topic you've mentioned has langer cusps than yours and it's from the Eocene, while the condition of a Eocene tooth from Hoevenen would be much worse generally. Same for Brachycarcharias lerichei, this is a species that lived until the Eocene so one in this condition from that location would be very unlikely.

My lack of knowledge got me thinking wrongly again... I would never have thought of this as being a Lamna nasus, so thanks all for guiding me in the right direction!

Brachycarcharias was erected to account for the species lerichei because it seems to belong to a group more closely related to Carcharias than to Lamna or at least distant enough from Lamna to deserve a separate genus. It may be debatable whether a new genus needed to be named as lerichei seems like it could fit under a broader definition of Carcharias. Link to comment Share on other sites More sharing options...
