BellamyBlake Posted February 23, 2021 Share Posted February 23, 2021 I bought a set of shark teeth from the Eocene of Fürstenau, Germany. I have some pretty decent shots of them, though these are the only photographs available for now. 1 cm - 3.5 cm is the range Really I have no idea on species, and nor does the seller. Some appear to be sand tigers, and indeed upon researching the locality those are described from there. Others from that locality include Otodus auriculatus and Isurus praecursor, and those were the ones I was really after. And while I cannot seem to see any of the former, I do believe a few are Praecursor. I'm attaching photographs here. The third photograph has the teeth I believe to be Isurus praecursor highlighted. Could anyone confirm this? I'd also appreciate any IDs on the others. Thank you, Bellamy Link to comment Share on other sites More sharing options...

Notidanodon Posted February 23, 2021 Share Posted February 23, 2021 The ones with striations on the blade are likely striatolamia, they are a bit fragmentary to get a sold id 1 Link to comment Share on other sites More sharing options...
siteseer Posted February 23, 2021 Share Posted February 23, 2021 Hi Bellamy, First of all, the teeth from Furstenau do tend to look like those - broken or worn or broken and worn. The more slender of the circled teeth is too slender for Isurus praecursor. The other one may be an early mako. Jess 1 Link to comment Share on other sites More sharing options...

The bottom circled tooth certainly looks like the other Praecursor teeth I have, and it seems you also believe it could be. I'll go with that ID on that one :) Link to comment Share on other sites More sharing options...

From the angle provided it looks a bit flat for a mako and I think someone said the early ones from Europe are thicker than the early ones from North America.

Jess Thank you Jess, I appreciate the insight; I'll post more detailed photographs once they arrive. Those were just pics from the individual who sold them Link to comment Share on other sites More sharing options...

I got them in a trade a long time ago. Jess 1 Link to comment Share on other sites More sharing options...
