How do I tell whether teeth are modern or not?

Hey,

I was wondering what ways to tell whether teeth are modern or fossils, I know there’s the burn test for bones, but I was wondering if there was something like that for teeth? TIA!

Fossilized teeth are mostly black (but not always). More important is to know what modern and fossilized teeth you can encounter in a given place, so it's pure logic. If you see a big reptile tooth, it can't be modern, for example. Or a camel in the US. Or a fish in the woods. Modern teeth are mostly mammal from common animals: dog, cat, horse, cow, etc. So it's good to know how they look in the 1st place

In my experience, fossil teeth are NOT mostly black.  For a grand example, consider the teeth from Moroccan phosphates or Florida phosphates or from China.

 

RuMert does offer some good advice about distinguishing between fossil and non-fossil teeth:  Consider the context of the find.  And, as RuMert suggests, know your recent animals.  I suggest you build a comparison collection of modern and fossil teeth.

Thank you, I try my best to know first, but I was more talking about teeth that are in the area as fossils and modern teeth. I’ve got a raccoon tooth from Florida, and I was in the tanin stained water so I can’t tell by color, I was wondering what I could do to see if it’s modern or a fossil.

Thanks, Harry:tiphat:

@Familyroadtrip, I don't know if there are easy and affordable methods of telling modern and fossilized teeth apart if they look the same. Fossilized material from a given locality usually has a specific manner of preservation. So I'd keep anything that looks in this manner. If there are raccoons in your formation and your tooth looks like raccoon's and has that preservation type, why not accept it's fossilized?

The tooth I’m talking about is a raccoon molar from Florida, but if it’s a fossil it’s ice age, so it wouldn’t look to much different for a raccoon molar. The guide we went with couldn’t tell if it was a fossil or modern(he was more of a shark tooth person, and wasn’t a familiar with mammal fossils), but it was in the water, so I can’t go off of color, if you try burning the root of the tooth, would that work?

Ok, it’s almost exactly 3/8 of an inch from tip of the tooth to the bottom of the root.

Root measurements are not useful.  Length, width, and (sometimes) height of the enamel crown are significant.  If I had found this tooth in the Peace River, I would call it recent just based on its appearance.  Recent raccoon remains are far more common than fossil raccoon.

Yeah, it was found on the peace river. thanks for the help! The guide said he thought it was modern, but not new either, he thought maybe a couple hundred years old, would you agree with that, or newer?

I think the 'coon died on February 12, 2018 -- just my speculation.  Two years or two hundred years old is just not significant when you're collecting fossils.
