Paleontology

A branch of science concerning the scientific study of life from ancient times is known as paleontology. The scientists working on paleontology are known as paleontologists. Paleontologists collect the fossils of organisms from ancient times to classify them. The paleontologists also study the environment from ancient times to study the interactions between different organisms.
