Have no clue what kind of tooth this is. Any help greatly appreciated. Found on Amelia Island Florida.

I agree with Edd, it's a deer tooth.

Dumb question: why are so many teeth black? Is the black color present for modern teeth as well as fossilized?

Info: Craig Hyatt, retired software/electrical engineer

Experience: Beginner, fossil hunting less than a year

Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert

Formation: Escondido, Marine, Upper Cretaceous

Materials: Sandstone, Mudstone, Shale, Chert, Chalk

Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus

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.

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.

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.

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.

Thanks for that, Tony! :)

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.

My wife is Vietnamese. Some old photos of her relatives showed blackened teeth. 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.

The other question I had, aside from age, is why black is such a popular color. 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.

I think the color of teeth, found outside their living owner, has more to do with the minerals in the environment they were deposited.

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.

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