Cyanobacteria are microscopic and hard to see, unless they live in colonies like stromatolites. Their carbon rich residua may Stromatolites are formed through the activity of primitive unicellular organisms: cyanobacteria (blue-green algae) and other algae. These grow through sediment By the Late Archean, stromatolites (microbial mat-like structures) started to appear in the rock record. Stromatolites are the most common Precambrian fossils.

Stromatolites are a major constituent of the fossil record for about the first 3.5 billion years of life on earth, peaking about 1.25 billion years ago. They subsequently declined in abundance and diversity, which by the start of the Cambrian had fallen to 20% of their peak.

In fact, sedimentary structures that are around 3.5 billion years old are believed to be the oldest evidence of life on Earth. A stromatolite is a preserved structure in sedimentary rock that is a series of thin layers of sediment. These layers formed when a colony of algae trapped loose sediment particles. Stromatolites occur in rocks that range in age from very recent to more than 3.5 billion years old.

Stromatolite definition, a laminated calcareous fossil structure built by marine algae and having a rounded or columnar form.

Abstract - Subtidal columnar stromatolites up to 2.5 m high near Lee Stocking Island in the Exuma conch has been dated using 14C and has an age of 480.

Stromatolites have been recorded in many parts of Western Australia. Geologists from GSWA use fossil stromatolites as a mapping tool, specifically to correlate rocks across vast distances of the State. This correlation helps geologists to work out the age of rocks that cannot be dated using other methods such as radiometric geochronology. 1997-04-15 · Stromatolites are thought to have been common from 3.5 billion years ago until multicelled animal predators became common about 600 million years ago. Fossilized stromatolites, first found in the Gunflint formation, have subsequently been found in numerous places around the world, including Steep Rock Lake near Atikokan in northwestern Ontario. These structures are modern equivalents of the earliest signs of life on Earth, with fossilized stromatolites being found dating from 3.5 billion years ago at North Pole near Marble Bar, in Western Australia, and are considered the longest continuing biological lineage.
