World’s oldest fossils unearthed

[Dalia]

Hello, i make a thread about this subject pretty interesting

Tiny filaments and tubes formed by bacteria that lived on iron were found encased in quartz layers in the Nuvvuagittuq Supracrustal Belt (NSB), Quebec, Canada.



The NSB contains some of the oldest sedimentary rocks known on Earth which likely formed part of an iron-rich deep-sea hydrothermal vent system that provided a habitat for Earth’s first life forms between 3,770 and 4,300 million years ago.

Little tiny tunicates.

We are related to them, actually.

These are animals not plants.

I would call them more small organisms .

Microorganisms are etymologically "small organisms", so living beings so small that they are observable only under the microscope.
This term includes a variety of very different species, whether prokaryotic (bacteria) or eukaryotic (yeasts, algae). Some also include viruses, although they are on the verge of living.
