53: The Great Fossil Debate

At long last, we finish the cliffhanger from Episode 52!

Last time, I introduced one of the greatest debates in paleontology and geology. Are a few little triangles on the Greenland tundra Earth's oldest visible fossils, or just some funny-looking rocks? Today, we'll discuss both sides like a court case, laying out a decade of debate. This has been an episode Dylan has waited a long, long time to produce!

About the Podcast

Bedrock: Earth's Earliest History
Explore Earth's history from the beginning.
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.
