Paleontology is the study of fossils and includes their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils rock if they are over 10,000 years old. On the other hand, The oldest fossils are from around 3.48 billion years old to 4.1 billion years old. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host.
Fossils rock vary in size from one micrometer bacteria to dinosaurs and trees, many meters long and weighing many tons. Therefore, Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces (coprolites). Thus, these types of fossil are called trace fossils or ichnofossils, as opposed to body fossils. Some fossils are biochemical and are called chemofossils or biosignatures.
