Stromatolites are layered bio-chemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of micro-organisms, such as cyanobactria. The real significance of stromatolites is that they are the earliest fossil evidence of life on Earth.
