Scientist strengthens tools to track animal, ecosystem responses to environmental changes

By charting the slopes and crags on animals’ teeth as if they were mountain ranges, scientists have created a powerful new way to learn about the diets of extinct animals from the fossil record. Understanding the diets of animals that lived long ago can tell researchers about the environments they lived in and help them piece together a picture of how the planet has changed over deep time.
