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!
