Fossils are the preserved remains or traces of ancient living organisms that lived millions of years ago. They include the hard parts of an organism, such as bones, shells, and teeth, as well as imprints or impressions of soft tissues, like leaves and footprints. Fossils can provide important clues about the evolution and history of life on Earth, as well as about the geological processes that have occurred over time. They are typically found in sedimentary rocks, which are formed by the gradual accumulation and compression of layers of sand, silt, and other materials over millions of years.
