Teeth identification

[jan09]

Hello,

I found this teeth at a beach on the great ocean road in Australia.

Has anyone a idea of which species it could be?

Thanks
Jan

I don't know what or how big that coin is, but there are a LOT of web resources you can look through.
For example, Finding Seaside Shark?s Teeth and Creating DIY Jewelry : The Scuttlefish.
My first guess would be a sand tiger, by the way. Or a sand bar, if the tooth is small.

Thanks for your reply. The Australian 2 Dollar coin is 20.5mm in diameter.

When I checked pics of Sand Tiger Sharks they all seem to have small "tips" next to the teeth ( sorry, I dont know how to describe it better in english).

Thanks for the web resources.

Yes, that is a characteristic of the sand tiger teeth, but I'm not sure it is always there. The tooth is too big for a sand bar shark, but the right shape, I think.

What is the shape from the side? I have a number of sand tiger teeth and from the side they all curve.

Perhaps the "tips" had been worn off by the sand.
