Hexanchus 2

An 8mm tooth from the same family. This comes from a sulphur mine in Morocco. I got a kilo with teeth and the vast majority of them in pieces and with damage. I kept dozens of different teeth in the best possible shape to myself and gave the rest to a biology colleague.  I had to use a magnifying glass to get a little more detail in the photo.   It's not the smallest, which is about 1.5mm.
