Listed in the World Heritage, Shark Bay’s stromatolites are modern living stromatolites that are 2000 to 3000 years old. Perfect for healers and spiritual seekers. Cyanobacteria released oxygen as a byproduct of the photosynthesis. Bernhard, Edgcomb, and colleagues looked for foraminifera in living stromatolite and thrombolite formations from Highborne Cay in the Bahamas. Stromatolites are dominated by cyanobacteria that shed their polysaccharide sheaths and move up in search of light in an incremental process (often less than 1 mm per year). Stromatolites need sun to perform photosynthesis, which is why they are found in shallow waters. remains are presumed to be colonies of cyanobacteria, younger (that is, Proterozoic) fossils may be primordial forms of the eukaryote chlorophytes (that is, green algae). Stromatolites have been traced back over 3.5 billion years to the early Archean period; giving them the title of the longest living a… Some of the first forms of life on Earth are recorded in stromatolites present in rocks 3.5 billion years old. Stromatolites near Shark Bay in Australia. Cookie Policy These structures are made by the activities of microbes. A reasonable guess might be hard coral, but coral has only been in existence a mere 542 million years, or since the Cambrian Period. On a concluding note, many geologists are of the opinion that cellular life may have existed millions of years before the signs appear in the fossil record, and believe that the study of rock-like structures called stromatolites and microbially-induced sedimentary structures might help them find traces or origins of cellular life or early life forms on Earth. In a previous forum post where I asked for travel advice, I asked if the approx two-day roundtrip north from Perth to see the stromatolites in Shark Bay was worth the diversion. Consequently the origin of precambrian stromatolites has been a subject of considerable controversy. Living stromatolites can still be found today, in limited and widely scattered locales, as if a few velociraptors still roamed in remote valleys.
