\n"A dome-shaped structure consisting of alternating layers of carbonate or silicate sediment and fossilized algal mats. Stromatolites are produced over geologic time by the trapping, binding, or precipitating of sediment by groups of microorganisms, primarily cyanobacteria. They are widely distributed in the fossil record and contain some of the oldest recorded forms of life, from over three billion years ago. They continue to form today especially in western Australia."

\nLife:
\n(Taken from Wikipedia, but we've learned this before...)
\nConventional definition: Often scientists say that life is a characteristic of organisms that exhibit the following phenomena:
\n(Processes of life)
\n 1. Homeostasis: Regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature.
\n 2. Organization: Being composed of one or more cells, which are the basic units of life.
\n 3. Metabolism: Consumption of energy by converting nonliving material into cellular components (anabolism) and decomposing organic matter (catabolism). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life.
\n 4. Growth: Maintenance of a higher rate of synthesis than catalysis. A growing organism increases in size in all of its parts, rather than simply accumulating matter. The particular species begins to multiply and expand as the evolution continues to flourish.
\n 5. Adaptation: The ability to change over a period of time in response to the environment. This ability is fundamental to the process of evolution and is determined by the organism's heredity as well as the composition of metabolized substances, and external factors present.
\n 6. Response to stimuli: A response can take many forms, from the contraction of a unicellular organism when touched to complex reactions involving all the senses of higher animals. A response is often expressed by motion, for example, the leaves of a plant turning toward the sun or an animal chasing its prey.
\n 7. Reproduction: The ability to produce new organisms. Reproduction can be the division of one cell to form two new cells. Usually the term is applied to the production of a new individual (either asexually, from a single parent organism, or sexually, from at least two differing parent organisms), although strictly speaking it also describes the production of new cells in the process of growth.

\n
\n"Evidence of ancient cyanobacteria (also called blue-green algae) is provided by interesting rocklike formations of limestone called stromatolites. During countless centuries of time, calcareous sediments (limestone) and other materials are trapped in layers of filamentous colonies of cyanobacteria."
\n
\n"Stromatolites are formed through the activity of primitive unicellular organisms: cyanobacteria (which used to be called blue-green algae) and other algae. These grow through sediment and sand, binding the sedimentary particles together, resulting in successive layers which, over a long period of time, harden to form rock. For at least three-quarters of the earth's history stromatolites were the main reef building organisms, constructing large masses of calcium carbonate."
\n
\nThe rock is layers of...rock (lime), produced by the cyanobacteria's photosynthesis. I'm guessing since they need sunlight, they "trap (and etc)" sedimentary grains as so not to obstruct their source of light.
