Listen for free

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.

    Today, we visit the three major locations for Season 3. A three-ring circus of rocks, if you will. One area is a remote desert full of ancient fossils. One area is a forested mountainland with evidence for global catastrophes. One area is our most populated region yet, full of iron mines. Dylan has visited two of these three locations, and hints at a few personal field stories that will set Season 3 apart.

    56: The Council of Time (Season 3 Premiere)
    Sep 24 2026

    Welcome to Season 3 of Bedrock!

    This season will cover the Paleoarchean Era, from 3.6 to 3.2 billion years ago, or March to April on the "Earth Calendar". Get ready for more fossils and strange new rocks! In this episode, we'll see why Season 3 begins and ends when it does: an extinction? an impact? or something more random?

    On the way, we'll visit geology's great "Council of Time", meet a bishop who was a founder of modern geology, and make a cake on the edge of the Grand Canyon.
