They are fossils cyanobacteria from the Archaean eon.
The oldest cyanobacteria fossil found is about 3.5 billion years old, known as the Apex chert fossils from Australia. These fossils provide evidence of the early existence of cyanobacteria, which played a significant role in shaping the Earth's atmosphere and environment.
Stromatolites have been dated back to as far as 3.4 billion years ago, and are amongst the oldest known fossils found on Earth. Stromatolites are still present today, and can be found in very salty lakes, and marine lagoons.
Prokaryotes are estimated to have been around for about 3.8 billion years, while eukaryotes are thought to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 2.2 billion years older than eukaryotes.
The oldest known fossils are prokaryotic. These fossils, dating back over 3.5 billion years, are believed to be ancient bacteria and archaea. Eukaryotic cells are thought to have evolved later.
In undisturbed strata, the oldest fossils will be the deepest from the surface.
The oldest known fossils are up to 3.5 billion years old.
3.5 billion years
Fossils have been found with ages from a few tens of thousands of years old to roughly three billion years old.
3.5 billion years ago. It was bacteria
Approximately 3.465 billion years old

The oldest known fossilized prokaryotes were laid down approximately 3.5 billion years ago, only about 1 billion years after the formation of the earth's crust.
Prokaryotes are estimated to have been around for about 3.8 billion years, while eukaryotes are thought to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 2.2 billion years older than eukaryotes.

In undisturbed strata, the oldest fossils will be the deepest from the surface.
The worlds oldest fossils were found in an ancient beach in Austrila, they are 3.4 billion years old and are fossils of cells. They have no bones and are mineralized spheres.
