Microbial Mat- Paleoarchean

Paleoarchean microbial mats are 3.3 to 3.5-billion-year-old fossilised sheets of microscopic life that represent the oldest definitive evidence of life on Earth.Discovered in pristine condition within the ancient volcanic and sedimentary rocks of Western Australia's Pilbara region, these ancient biological structures predated the dinosaurs by billions of years. They provide scientists with a direct window into how primitive organisms lived on a volatile, young Earth.
