Stories trapped in ancient teeth: Reconstructing megalodon’s diet and retracing the steps of woolly mammoths

Tiny Matters

How often do you think about your teeth? In this episode of Tiny Matters, we talk about how the atoms trapped within teeth can reveal what an animal ate and where it lived, and how studying teeth has helped ecologists reconstruct prehistoric food webs of megatooth sharks and retrace the steps of woolly mammoths across the Arctic. And hopefully, we’ll give you a few new reasons to appreciate your own pearly whites.
