Fossils are not present in the rocks of the archaeozoic era.
The Archean Eon or Archaean is one of the four geologic eons of Earth history, occurring 4,000 to 2,500 million years ago (4 to 2.5 billion years ago). During the Archean, the Earth's crust had cooled enough to allow the formation of continents and life began its development.
Archaeozoic - the time from 3,800 million years to 2,500 million years ago; earth's crust formed; unicellular organisms are earliest forms of life.
Q. Archaeozoic era is considered as the age of
Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
