Dave talks to Russell Shapiro, a geology professor at California State University at Chico. Dr. Shapiro has a fascinating array of interests and adventures from seeking evidence for ancient life on Earth to helping NASA craft science goals searching for evidence of ancient life on Mars.
Shapiro is also a seasoned paleontologist who regularly works in the field and recently helped uncover one of the great fossil finds in California history, unearthing Miocene period mammals that dominated the California landscape sometime between 5 and 20 million years ago.
It's a trip through space and time you won't want to miss!
