Hi There,
I just wanted to confirm that I think (?) these are examples of the large Sand Tiger shark from the Chattian. Jaekelotodus trigonalis ? ... This time period is not one I'm yet familiar with. Though, it is in a similar area to where the O. auriculatus I just received was found.
Mangystau (Mangyshlak), Kazakhstan
The preservation in this area is poor but the teeth are much larger. You can see the cusps have been worn down/away
