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.
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.
Agnatha, also known as jawless fish, are the oldest vertebrate fossils with no jaws. This group includes ancient species like the ostracoderms and the agnathan fish.
The oldest fossils can typically be found in sedimentary rock layers, specifically in locations with well-preserved rocks that have not undergone significant geological activity like metamorphism. These fossils provide valuable insight into the Earth's early history and the evolution of life.
The oldest terrestrial insect fossils are found in rocks dating back to the Devonian Period, approximately 400 million years ago. These fossils provide insight into the early evolution and diversification of insects on land.

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.
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
The fossils of the oldest life forms can be found in the Precambrian period of the fossil record.
The geologic column is the result of the core sample showing layers of artifacts and material. Since some of these can be carbon dated, a relative time period can be established.
The oldest humanoid fossils were all found in Africa.
The oldest micro fossils are comprised of carbon. This is because they have been in the ground a very long time and it compresses the materials into carbon.
The oldest known fossils are up to 3.5 billion years old.

A geologic column is an arrangement of rock layers in which the oldest rocks are at the bottom. The upper part of the column is rich in fossils.
It is an imaginary column where are the ages of rocks sit on top of one another in their proper age sequence, oldest at the base and youngest at the top. An ideal sequence of rock layers that contains all the known fossils and rocks whith each sequence is given its name.
