Weird sharktooth from Hoevenen

[Max-fossils]

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

Maybe it is a brachycarcharias sp. But I am not an expert. So lets wait until there are some other answers

It looks like Lamna nasus.

Maybe you are right. Thanks for the help!

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?

 

Best regards,

Looks like a Lamna tooth to me

Another name for Brachycarcharias lerichei is Lamna lerichei

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.

Seems like I was wrong... Sorry @Al Dente !

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!

 

Best regards and thanks for your help,

But in hoevene you can find teeth from the eocene too.

Yeah. Species like Otodus aurculatus and abdounia sp. are from the eocene

Actually, Lamna lerichei is the old name from back when many teeth of this general shape were considered species within Lamna.  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.
