Bedrock: Earth's Earliest History

無料で聴く

This podcast starts at the beginning of Earth's prehistory and works forward through time. Bedrock will explore the first 90% of Earth’s past, a time known as the Precambrian Era. Before humans, before dinosaurs… there was the Precambrian. The Earth was an incredibly alien world, but not a dead one. Along the way, you will build a mental toolkit to see the world like a geologist. You will never look at a mountain, the moon, or pond scum in quite the same way again. Welcome to Bedrock.

    Mail Time! Dylan answers your questions
    2026/08/27

    While we're on a break between seasons, and while I'm starting my new job, I figured this would be a nice palate cleanser. There's no script, just answers like I'd actually give in person.

    If YOU want your question to be on a future Mail Time (and listen to bonus episodes), join our Patreon here!

    Today, I talk about the day I fell in love with "fossil pond scum", some of my favorite field locations, and my favorite time period in Earth history. Enjoy!

    Season 2 Finale!

    For 50 years, the title of "USA's Oldest Rock" was held on the prairies of western Minnesota. In 2025, that throne was usurped by a brand new study. Where is this "new" ancient location, what rocks are here, and how old are they? Stay tuned to find out!

    Dylan has an exciting announcement: he has a new visiting professor job at Gustavus Adolphus College in Minnesota! Thanks to everyone for their support.
