Paleontological evidences
• The study of fossil is called paleontology.
• Fossils are the remains or impressions of past organisms preserved in sedimentary rocks or other media.
• Different-aged rock sediments in earth’s crust indicate the presence of fossils of different life forms which died during the sediment formation.
• A variety of fossils ranging from the modern organisms to extinct organisms can be observed.
• By studying the different sedimentary layers, the geological time period in which the organism existed can be predicted.
