Key concept: Most plant fossils are impressions, but the ones in  Clarkia, Idaho are actual leaves encased in rock for the last 15 millions years… and we might be able to use their DNA. Guest experts for this episode of “Plants are Cool, Too!”: Drs. Bill Rember, Dave Tank, Hannah Marx, and Simon Uribe-Convers, all from the University of Idaho.

Hosted by Chris Martine, Bucknell University.

Producers C. Martine, Paul Frederick, Tim Kramer. Shot and edited by P. Frederick.
