Dinosaur teeth

[Capmaker2 <Capmaker2@aol.com>]

Does anyone know if a chemical or structural analysis of dinosaur teeth has
ever been done to see if the actual enamel survives (vs fossilization).

If enamel does fossilize completely it would be at a much slower time frame
than dentin, cementum or bone.  Does anone knows the time frame.

I am a dentist and  have been asked to give a little talk on dinosaur teeth to
my son's 2nd grade class.  Any light that anyone can "shed" ( pun intended)
would be greatly appreciated.

Thanks  very much.
