Cyanobacteria are considered to be the organism that has been recorded as the oldest fossil ever found. They are first dated from the archaeon rocks of western Australia, and it is categorized to have lived more or less 3.5 billion years ago. Cyanobacteria are aquatic unicellular organisms, which can produce their own food through the process of photosynthesis. Hence, they are known to grow on a large scale, which can be distinguished easily by the naked eye.

Cyanobacteria
