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.
