Stromatolites are _____.
Stromatolites are structures built by cyanobacteria (blue-green algae) in quiet waters. Cyanobacteria use water, carbon dioxide, and sunlight to create their food. The byproducts of this process are oxygen and calcium carbonate (lime). [ A layer of mucus often forms over mats of cyanobacterial cells.
In life they are mounds, during high tides or storms they become covered with sediment, then grow a new layer of bacteria on top. When stromatolites are fossilized, erosion uncovers them. Stromatolites are rather rare today, but at various ages in the past they were very common.
Stromatolites and their close cousins the thrombolites, are rock-like buildups
A single stromatolite can take thousands of years to form, layer by layer, and it may appear in a variety of shapes many stromatolites look like columns, but they can also form in discs, pyramids, and rings like giant misshapen donuts.
EDIT - Sediment sticks to the surface of the
living algae, forming a crust. In turn, the algae grows through the sediment to form a new layer of living matter. A new film of sediment sticks to the algae and so on. The resulting structure looks like a mound. http://answers.yahoo.com/question/?qid=20090221071056AAfJ01c
