MCG DAWG Posted June 27, 2016 Share Posted June 27, 2016 Have no clue what kind of tooth this is. Any help greatly appreciated. Found on Amelia Island Florida. Link to comment Share on other sites More sharing options...

Trilobiting Posted June 28, 2016 Share Posted June 28, 2016 I agree with Edd, it's a deer tooth. "Fossils have richer stories to tell about the lub-dub of dinosaur life than we have been willing to listen to." - Robert T. Bakker Link to comment Share on other sites More sharing options...
CraigHyatt Posted June 28, 2016 Share Posted June 28, 2016 Dumb question: why are so many teeth black? Is the black color present for modern teeth as well as fossilized?

Fossildude19 Posted June 28, 2016 Share Posted June 28, 2016 Craig, I'm sure it has something to do with the mineral replacement of the enamel and bone during the fossilization process. Modern shark teeth and mammal teeth are white (or yellow, depending on dental habits.) as far as I know.

CraigHyatt Posted June 28, 2016 Share Posted June 28, 2016 Thanks, Tim. So those black deer teeth aren't modern, right? That's one reason I asked. I've noticed that many of the teeth posted here for mammals are solid black, but it's not always made clear if they are modern. Can relatively modern teeth--say < 1000 years old--be black? Edit: Of course, I realize there are no hard and fast rules. We can only generalize.

Fossildude19 Posted June 28, 2016 Share Posted June 28, 2016 Correct. I have seen modern bones turn brown/dark brown in very little time (geologically speaking) spent in the river. Not sure the same can be said for teeth. I would think not. So the black teeth are all probably fossil. Someone will be sure to let me know if I am wrong on this.

ynot Posted June 28, 2016 Share Posted June 28, 2016 Bone and the enamel of teeth are very porous and can be stained quite easily. If the minerals in the water are concentrated enough then it could die the teeth or bone very quickly. Look at the teeth of the pacific islanders that chew betel nut, they turn black while still in the owner's mouth. Tony Darwin said: " Man sprang from monkeys."

JohnJ Posted June 29, 2016 Share Posted June 29, 2016 Based on all kinds of mammal teeth I've seen from many different time periods, I don't think you can use color as an indicator of age. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

I asked her about it, thinking it was tooth decay, (she's a dentist), and she said that long ago Vietnamese women did it as a status symbol. She said it was done by painting with some sort of black lacquer. In other cultures, it's done by chewing betel or drinking an iron-based black dye, according to wiki. Thanks to everyone for the info.

Why not pink, blue, or orange?Edit: Mystery solved. I mentioned earlier that some cultures use an iron-based dye to stain their teeth black. So, duh, iron is extremely common in the environment which explains all the black teeth. In fact, even the small amount of iron in supplements and food can stain teeth black.

tmaier Posted June 29, 2016 Share Posted June 29, 2016 I think the jet black color is from carbon, not iron. Link to comment Share on other sites More sharing options...
JohnJ Posted June 29, 2016 Share Posted June 29, 2016 I think the color of teeth, found outside their living owner, has more to do with the minerals in the environment they were deposited.

ynot Posted June 29, 2016 Share Posted June 29, 2016 I think the jet black color is from carbon, not iron. There are several minerals that create a black colored fossil. Iron and carbon are just the most recognized/common. Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

CraigHyatt Posted June 29, 2016 Share Posted June 29, 2016 Next time I find some mammal teeth, I am going to put them in jars of water with different metals to see what happens.
