About this episode

This episode explores the formation, discovery, and variety of fossils with guest Charlotte Mehrtens.

What is a fossil? How are they formed? Where are they found? What’s the oldest fossil, and what’s the biggest? When you think of a fossil you might be picturing a full dino skeleton preserved at a museum. But fossils come in many different shapes and sizes. We taped this episode all about fossils in front of a live audience at the South Burlington Public Library in Vermont, with special guest Charlotte Mehrtens, a retired geology professor from the University of Vermont.
