Detailed explanation-1: -If you think you found a fossil, the most important thing to do is to leave it exactly where you found it. When paleontologists study a fossil, it is very important to know precisely where it came from to learn more about it. The location can tell us how old the fossil is and what other fossils may be around it.
Detailed explanation-2: -Fossils are traces of organisms that lived in the past. When fossils are found, they are analyzed to determine the age of the fossil. The absolute age of the fossil can be determined though radiometric dating and determining the layer of rock in which the fossil was found.
Detailed explanation-3: -Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.
