Stromatolites

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. The Strelley Pool Formation is dated to more than 3.5 billion years old and found in Australia. This formation is within the Pilbara Supergroup and an extremely important site for scientists to study.
