By the close of the Proterozoic, the abundance of stromatolites decreased markedly, though cyanobacteria continued to leave a fossil record, such as Langiella and Kidstoniella known from the Lower Devonian Rhynie chert. 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.
