stromatolite

stromatolite A rocky cushion-like mass formed by the unchecked growth of millions of lime-secreting cyanobacteria. Stromatolites are found only in areas where other organisms that would normally keep down the bacterial numbers cannot survive, such as extremely salty bays. Such bacteria were abundant during the Proterozoic and Archaean eons, perhaps from as early as 3900 million years ago. The white rings of fossilized microorganisms found in rocks of this age are the remains of stromatolites.

stromatolite

stromatolite A rock-like or firmly gelatinous structure, built up over long periods of time from many layers or mats of cyanobacteria together with trapped sedimentary material. Stromatolites are found mainly in shallow marine waters in warmer regions. Some are still in the process of being formed, e.g. those in Shark Bay, Western Australia. Fossil stromatolites dating from the Early Precambrian are also known, although it is not certain that these were formed by cyanobacteria.

stromatolite

stromatolite A laminated, mounded structure, built up over long periods of time by successive layers or mats of cyanobacteria that trapped sedimentary material. Stromatolites are found in shallow marine waters in warmer regions. Some are still in the process of being formed, e.g. those in Shark Bay, Western Australia; fossil stromatolites dating from the Early Pre-cambrian are also known, although it is not certain that these were formed by cyanobacteria.
