The first direct evidence of primitive cellular life was the 1977 discovery of <u>microbial </u>fossils in the swartkoppie chert, a type of granular sedimentary rock rich in silica.

Some of Earth's high-quality-preserved fossil microorganisms occur in rocks from the Ediacaran period of geologic time, which runs from about 635 to 541 million years ago. Scientists do not absolutely apprehend how this fragile microorganism became fossils. however, a new experimental look at is now dropping more mild.

Some microorganisms secrete iron-coated sheaths that on occasion fossilize. Others may additionally bore into shells or rocks and shape microscopic canals in the shell; such microorganisms are referred to as endolithic, and their borings can be identified at some point of the Phanerozoic.

The earliest regarded fossils on the planet are putative fossilized microorganisms determined in hydrothermal vent precipitates, taken into consideration to be about three.42 billion years old.
