So you can see like literally dinosaur bones that are like fragmented and look like wood.

No, I mean, things die out there and then get flooded over or buried secondarily.

Yeah.

So on diet, we know a bunch about what animals ate based on their teeth in general, just morphology.

So people will actually quantify the shape and then be able to be like, okay, this is best for this kind of diet or this kind of diet.

But also, especially more recently, people are taking the enamel, analyzing the isotopes in there.

So maybe you can explain what isotopes are.

But basically, they can find isotopes that link to diet.

So now we know that some dinosaurs were eating like C4 plants or like this type of plant.

Or we know they ate more seafood because that has a different type of isotope.

So teeth shape-wise will inform diet.

Chemistry-wise will also inform diet.

Super interesting.

Yeah, it's the actual enamel that holds onto it because basically these animals are replacing their teeth all the time, right?

So constantly, whatever they're eating is what's getting incorporated into their tissues and then expressed in their enamel as they make new enamel.

So it's kind of like a continuous dental history, continuous chemical history.

I don't, although my most recent paper did get covered in a creationist article.

What did they say?

Well, they said that I needed Jesus.

They said that teeth have been around forever and therefore my study was wrong and I hadn't considered this and that and that I need Jesus.
