Pale Blue Dot

This week we dive into an introduction of fossils - what exactly are they? Is a turd considered a fossil? How have they helped define periods in our vast geological time scale? Fossils can invoke feverish pursuit of the perfect specimen and give windows to the lives past that otherwise would be lost to time.

Hosted by Dr Luke Nothdurft and Dr David Flannery.
