Fossils are among the most valuable sources of information about the Earth's history. They tell us about the organisms that lived on Earth from the time of the oldest fossils, about 3.8 billion years ago, to the present. By studying fossils we can learn not only about the creatures and plants of the distant past, but how they grew, what they ate, how they interacted, and many aspects of their behavior.

Study of fossils has led to important new understanding about how life evolved on earth and about diseases, both ancient and modern. Fossils also help us understand past climates, including ice ages and periods that were warmer than our present climate. Knowledge from the study of fossils is helping geoscientists understand global warming and its effects. By studying the catastrophic extinction of the dinosaurs and many other life forms at the end of the Cretaceous Period, geoscientists have gained insight into the evolutionary implications of impacts by extraterrestrial objects. Investigating the physical and chemical characteristics of fossil organisms that lived during times of drastic climatic change helps us understand the implications of the changes we are making in our own environment.

\huge\textbf{Fossils :}


The dead and decay parts of plants and animals that were under Earth's crust and by excess pressure and temperature they convert into fossils.


\textbf{Importance of Fossils :}


→ The study of fossils have helped us to know about the evolution or the link between two species. Fossils tells us how new species are developed from the old. 

→ It tells us how old the species is. The species that found above Earth's crust are new. While that found below Earth's crust are old species.
