Bedrock: Earth's Earliest HistoryExplore Earth's history from the beginning. Author: Dylan Wilmeth
This podcast starts at the beginning of Earth's prehistory and works forward through time. Bedrock will explore the first 90% of Earths 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.

52: The Thing in the Ice
Thursday, 8 January, 2026
Until now, all the clues for ancient life have been microscopic, beyond the realm of sight. Today, that begins to change. Ten years ago, a team of scientists showed the world a weird, lumpy rock that they claimed was the oldest microbial colony. Like a sci-fi movie, this specimen was found under melting ice in the high Arctic, unveiled from 3.7 billion years ago. But is it actually a fossil? Welcome to the debate that has defined my corner of geology. Extra Credit: Check your house for hard water damage, or watch The Thing (1982). Want bonus content? Check out the Patreon!
