Well, it helps them because the more specimens you get of shark teeth, the better your ability to dissect or decide let’s say what they are, and who they’re related to. Associates tell you a lot more because they tell you about the relationship of the teeth to each other in the jaw. And then you can see whether they’re related to modern sharks or not. So shark teeth, I guess, help us better to understand who’s related to who, and who evolved from who, and maybe what’s gonna happen in the future. And have the shark teeth that you have.
