Fossil Imprints of Rain Reveal Clues About Early EarthIn South Africa, 2.7 billion years ago, it rained. We don’t know how much, and we don’t know what day, but we know it happened. How? Fossilized rain drops.
These newly discovered impressions, made when fresh volcanic ash was rained upon, and then covered by more sediment, reveal clues to our early atmosphere. The scientists behind the study say that these fossilized pock marks tell them that our atmosphere was not much more dense back then than it is today, and perhaps less. This aids in understanding the evolution of our climate over time based on the sun’s varying output.
Whatever the case, never let a rainy day get you down. It could be someone’s window back in time!
