What is the significance of scientists studying fossils now?

Significance of studying fossils: After all kinds of weather, geography and human harmony, fossils can be preserved and appear in the eyes of modern people. What are their functions, or why should we study them? The significance of studying fossils is to let human beings know the past better. As the title of the article says, what happened in those years, and how do we know?

Besides these, fossils are also important for geologists' research. According to fossils, geologists can infer the age of fossils from us, as well as the movement of the crust at all times and the distribution of some geological structures in specific areas.

Some microbial fossils in fossils can also be used as indicator fossils for people to find oil. Through the study of these tiny paleontological remains, we can obtain the age and oil storage information of underground rock formations.

Fossil formation:

1, organic matter must have hard parts, such as shells, bones, teeth or woody tissues. However, even very fragile organisms, such as insects or jellyfish, can become fossils under very favorable conditions.

Living things must avoid being destroyed immediately after death. If an organism's body is partially crushed, decayed or severely weathered, it may change or cancel the possibility of this organism becoming a fossil.

3. living things must be buried quickly by things that can hinder decomposition. The type of this buried material usually depends on the living environment of organisms. The remains of marine animals can usually become fossils, because marine animals sink to the bottom of the sea after death and are covered with mud. In later geological periods, mud became shale or limestone.

Fine-grained sediments are not easy to destroy biological remains. In some fine-grained sedimentary rocks of Jurassic in Germany, some fragile organisms such as birds, insects and jellyfish are well preserved.
