Stromatolites are laminated organo-sedimented calcareous structures formed by bacterias and other microorganisms, that are agglutinated due to diverse minerals such as calcium carbonate. They grow attached to a substrate and emerge vertically from it. Because of their rocky structure, stromatolites have the potential to persist as a fossil. Most fossilized cells were found in these rocks at the seashore. Fossil registers show that similar structured have been inhabiting earth since about <u>3.500 and 3.800 millions of years</u>, and they have maintained their evolutive line to the actuality.
