Notes
Paleoproterozoic was the first era of the Proterozoic eon (2.5 billion to 541 million years ago).Stromatolites are layered mounds, columns, and sheet-like sedimentary rocks. They were originally formed by the growth of layer upon layer of cyanobacteria, a single-celled photosynthesizing microbe that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils. Fossilized stromatolites provide ancient records of life on Earth by these remains, some of which date from more than 3.5 billion years ago. Stromatolites are still forming on earth today. Cyanobacteria were ultimately responsible for one of the most important global changes that the Earth has undergone. Being photosynthetic, cyanobacteria produce oxygen as a by-product. As stromatolites became more common 2.5 billion years ago, they gradually changed the Earth's atmosphere from a carbon dioxide-rich mixture to the present-day oxygen-rich atmosphere.
