On Earth, present day stromatolites are often found exposed at the surface as the water level drops or evaporates, and they have distinct mineralogies and morphologies from the surrounding rocks which typically helps distinguish them in the field. A stromatolite is a sedimentary structure formed when minerals precipitate out of water due to the metabolic activity of organisms in a microbial mat. One of the common fossils is of stromatolites, photosynthetic Bacteria that grew in layers and formed columns in shallow oceans. But it wasn't always like that.

Stromatolites, the biosedimentary products of microbe-sediment interactions, have the potential to provide significant information on the interaction of the biosphere, atmosphere, hydrosphere, and litho-sphere throughout the entire history of life on this planet. "Stromatolites are really important because they're actually the first evidence that we have of life on this planet, they go back nearly 3.5 billion years," Dr Camens said. The Hindu. Before the cyanobacteria, the air had only 1% oxygen. Carbon isotope dates indicate that stromatolites in the Stocking Island reef complex began forming 1000-2000 years ago. The sand and seagrass banks make it difficult for water to . important role in identifying stromatolites. They were the first known organisms to photosynthesis and produce free oxygen. The Oldest Fossils. These organisms, blue-green algae (picture of stromatolite, which is the rock formed by these algae), fed off atmospheric carbon dioxide and converted much of it into marine sediments consisting of the . Importance of Cyanobacteria. "Sharks we caught a great many of, which our men eat very savourily," wrote English explorer William Dampier in 1699. Photosynthesis is the only major source of free oxygen gas in the atmosphere.

Stromatolites are not only Earth's oldest of fossils, but are intriguing in that they are our singular visual portal (except for phylogenetic determination of conserved nucleic acid sequences and some subtle molecular fossils) into deep time on earth, the emergence of life, and the evolving of the beautiful forms of life of modern time. Why their discovery is important to understand geological history of the earth? Stromatoporoids are body fossils from a once living animal, whereas stromatolites are sedimentary structures left behind by a microbial mat. It is also the longest geologic eon, beginning 2.5 billion years ago and ending 541 million years ago.
