33: A Thin Line

What are the oldest disputed fossils on Earth? Why are they disputed?

Today, we wrap up our tour of Nuvvuagittuq in northern Quebec, 3.8 billion years ago, March 3rd on the Earth Calendar. In 2017, microscopic rusty threads were discovered inside these rocks, thinner than a human hair. Were they bacteria, or something else entirely? Stay tuned to find out!

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.
