You're not wrong about the size Michael, going from the what has been identified as a reliable correlation between the size of a shark tooth and body length of it's owner, you're looking at something in the region of 5 metres long! And that's just going off what's left of the tooth...

So in layman terms, what you have there is likely to be a fossilised front tooth from an ancestor of either: the Mako shark, (the Mako is usually considered to be The Great White's prettier sister); or it could be from an extinct form of GW.
Agewise, it could be between 2 and 37 million years old but to be more exact the paleontologist would have needed to see the rock and soil etc that it came from.
Pretty cool find eh?
