PART B_2

Fossils

Fossils are parts of an organism such as dead plants and animals from distant past. They are buried and preserved in sediment. Then, this sediment may form a rock in which fossils can be removed from it when the sediment is exposed at the Earth’s surface.

Most fossils are from organisms that lived 600 million years ago. There are various ways on how to tell rock ages. One of them is by using their radio-isotopic composition. This is very useful to determine the specific time an organism exists. In addition to that, the magnetic time zone helps in providing chronological evidence.

Fossil records provide evidence of the history of life. It tells when a specific organism lived on Earth. It is believed that life began over 3.5 billion years ago. Moreover, eukaryotic cells started to exist around 1.8 billion years ago. While photosynthesis expanded at a similar time that resulted in an increase in the oxygen concentration of the Earth’s atmosphere.

Fossil records can be studied in two ways. The first one is at a gross level conducted through the geological continuity of the rock sequence. The second one is at a finer level. It estimates the percentage of the total time range represented by the rocks when sediments were being deposited.
