Hello,
I´m not sure about the ID. For me the tooth looks like a Hemipristis or a bull shark tooth. The tooth is from the Indo-Pacific (Phillippines) and 1/2" (1,5cm) in lenght. I want to be sure with the ID because I do not want to buy a tooth of a protected species.
I don´t know, if the question is correctly ask in the Fossilforum, but I hope, that you can help me.
Kind regards from Germany
