This video provides some basic insight into Stromatolites are critical geological features as they are the only biogenic sedimentary structures that have an age range extending fully from the early Archean to the Recent, thereby demonstrating a fundamentally uniformitarian phenomenon. Stromatolites are the most common megascopic fossils, contained within ancient rocks dating to 3.5 billion years in age. In both the living and fossil form, they are created by the trapping and binding of sediment particles and the precipitation of calcium carbonate to the sticky surface of mat like filaments grown on a daily cycle by blue-green algae (also known as cyanobacteria).
