what’s a Stromatolite?: Stromatolites are the earliest fossil evidence of life on Earth. They were the first known organisms to photosynthesis and produce oxygen. They used water, carbon dioxide, and sunlight to create their food, and expel oxygen as a by-product. This particular examples of Stromatolites I have discovered dates from a period of over 750 million years.
