I'm not sure of the names, but sea animals. Like the underwater creatures before there were any dinosaurs roaming on Earth.
The fossils of the oldest life forms can be found in the Precambrian period of the fossil record.
The oldest fossil in the world is significant because it provides valuable information about the earliest forms of life on Earth. By studying this fossil, scientists can learn about the evolution of life and how it has changed over billions of years. This helps us understand the origins and development of life on our planet.

The oldest fossils in the world are found in western Australia and are those of primitive bacteria. They are about 3.5 billion years old.
Archaebacteria are the oldest and most primitive forms of life on planet Earth. It is postulated that primitive life on other planets would be most likely to resemble Archaebacteria. In addition, Archaebacteria were the first life forms to exist on Earth, so studying them allows xenobiologists to postulate how life may come into being on other planets.
SOMETHING haha i got you hehehahahoho
The oldest forms of life are found in the kingdoms Archaea and Bacteria. These are both prokaryotic organisms that have been on Earth for billions of years. They are known for their resilience and adaptability to extreme environments.
It is so because, the oldest fossils are obtained from the life forms which used to exist at that time in the oldest ages. At that time there was no so much changes in the world, the life forms being simpler. As the age of the earth advanced hence the forms of life also adapted or tried to adapt to the changes of the surrounding. The climate changed and so did the life forms. It was determined that in the older times, 1st life forms came in the water bodies and then from there the land forms developed. So as we see the later life forms are more complicated, thus the oldest fossils are more simpler compared to their most recent counterparts.

Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Single celled organisms like a bacteria and are some of Earth's oldest life forms.
