The process of formation of fossil in the rocks is called fossilization. Fossils found in layers of sediment give us clues to Earths past. Scientists compare rocks to other rocks to determine their age.
In this lesson were going. Sometimes fossils tell scientists how the Earth has changed. Now it begins to sink.
Fossil record can be regarded as history of life which was documented through fossils. The Paleo Pipeline is an example of the scientific process used to study fossil evidence. Most of the methods are indirect meaning that the age of the soil or rock in which the fossils are found are dated not the fossils themselves.
Describe what scientists can learn about the past by studying fossils. In many cases the age of the rock can be determined by other fossils within that rock. Lee Anne Zajicek BA.
Types of fossil preservation 4. Studying fossils helps them learn about when and how different species lived millions of years ago. This method has been used to.
