For the ones I find here in Florida, this is the biggest yet. Are the black ones recent or fossil? They look very old up close. What about gray one? Thanks.
Nice tooth, I have found 1000s of shark's teeth, both are fossilized, you will see them black, gray, brown, and even an off white color, the color comes from the sediments and minerals the tooth has been exposed too during the time it took it to become fossilized.
Unfossilzed teeth will almost always be a pearly white color, just like our teeth.
Great looking teeth there! When I was attending Venice elementary school I would walk home down a shell rock road from the bus stop and find teeth like that on a regular basis.
