FACTS ABOUT STROMATOLITES

Stromatolites or Stromatoliths is a kind of algae which was derived from Greek name 'STROMA' meaning layer and 'LITHOS' meaning rock .

They are layered mounds, columns, and sheet - like sedimentary rocks that were originally formed by growth of layer upon layer of 'CYANOBACTERIA' which is a single celled photosynthesizing microbe.

Fossilized Stromatolites provide records of Earlier Life on Earth. Lichen Stromatolites are a proposed mechanism of formation of some kinds of layered rock structure that are formed above water, were rock meets the air and repeated colonization of the rock by Endolithic Lichens.

There is something really interesting to know this chapter. Let's see what is it:

• When our Earth obtained water Stromatolites were the one to occupy the shallow water region.4

• They were the second organism to create oxygen in the Atmosphere and gave birth to life in the ocean ( Some millions of years later )
