Fossil Shark Tooth

Shark Tooth Fossil
These are shark teeth turned to stone, fossilized.  Pliny the Elder who died in the Mt. Vesuvius eruption of 79 AD thought they were objects which fell from the sky during lunar eclipses.  Danish naturalist Nicolaus Steno in 1667 correctly identified them as shark's teeth.  This one and the next one look so much like a tooth I can not see how they could be mistaken. I purchased these from Pam Laurer.  I think they are very nice.

Others, not shown look more or less triangular and I can see how they might be less identifiable.  Apparently, the teeth are about the only parts of the shark that fossilizes.  I obtained my information from Wikipedia.
