Stromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), especially cyanobacteria. Although they are rare today, they are a major constituent of the fossil record of the first forms of life on earth.

Stromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), especially cyanobacteria. Although they are rare today, they are a major constituent of the fossil record of the first forms of life on earth.
