Stromatolites and their close cousins the thrombolites, are rock-like buildups of microbial mats that form in limestone- or dolostone-forming environments. Together with oncoids (formerly called "algal biscuits" or "Girvanella"), they typically form by the baffling, trapping, and precipitation of particles by communities of microorganisms such as bacteria and algae. In some cases, they can form inorganically, for example when seawaters are oversaturated with certains chemicals resulting in precipitation. Stromatolites are defined as laminated accretionary structures that have synoptic relief (., they stick up above the seafloor). Stromatolite-building communities include the oldest known fossils , dating back some billion years when the environments of Earth were too hostile to support life as we know it today. We can presume that the microbial communities consisted of complex consortia of species with diverse metabolic needs, and that competition for resources and differing motility among them created the intricate structures we observe in these ancient fossils. Microbial communities diversified through time, with eukaryotic organisms eventually joining the mix.
