Dr. Angela Osen, Professor of Geology, helps JtG and BB, the two Geologist on the Rocks, navigate the wondrous world of marine sediments. The journey begins with adventures from the Arlington Archosaur Site and prepping fossils at a museum. In this episode we break down what sediments are; much like weathering did to the sources of lithogenous sediments. Ooids and Manganese nodules battle for weirdest sediment. There were a few twists, such as the demise of the dinosaurs (minus birds) at the K-T boundary, and turns that include why you should always plan for rafting boulders when in a submarine. The conversation closes with another great "That Freaking Rocks" segment and a secret confessions of phantomy musical operas.

Tune in and Keep it on the rocks!
