Stromatolites are rock-like constructions of multi-layered sheets of micro-organisms ( microbic mats ) that form in limestone. Stromatolites by and large form from the caparison and binding of atoms by micro-organisms e. g. algae and bacterium. and turn upward to acquire light from photosynthesis. Stromatolites provide scientists with some of the oldest records of early…
