mako or ancestral great white, can’t tell which without it being less worn

@bill-heim I excluded Isurus sharks because of its small size

In my smallest juvenile shortfin mako jaw, the slant height of the enamel of the equivalent tooth is 7mm

thank you, I will reconsider it then

Do you know the formation?

Pretty

Think tiger shark

@isaiah-hernandez yes it is extinct tiger shark

@bill-heim unfortunately no, but I may try to find it out.

@jenna-miller thank you, I tried to clean it but roots of the teeth are really fragile

Ok

ID is correct
