Isurus retroflexus?


Hastalis

Recommended Posts

Hello, I have found this tooth last year in Lučenec region, southern Slovakia. Age: lower Miocene/Eggenburgian (Central Paratethys). Scale is in cm. It looks like Isurus retroflexus tooth, but I want to be 100% about it. If it is the one, I can finaly add the first of this kind to my collection. Thank you in advance.

I am not the person to ID a shark tooth, but I just wanted to say these are great photos! Someone who is better versed in shark teeth will be along to help you soon.

Yeah, I'm not especially confident, but it seems plausible to me. The weak cusplets rule out other possibilities like lower lateral hastalis.

I would say so, yes.

 

Thank you for posting closeup photos of high quality from all angles needed for an ID.  Makes an identification much easier.
