Very enjoyable, thanks for posting that! The micro-fossil discussion was an education, and will have to look at some of my shales (Devonian) under a microscope. The driveway is shale gravel and full of decent shellfish fossils...betting there's small ones too.
I really wallow in our local geologic history (yankee end of the Appalachians, the Helderberg Escarpment north of the Catskills) from the unusual mountain building method creating the Appalachians to the recent mile of ice that sat on top of us.
