Most of the fossils can be found in various places like river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings. Fossils are the preserved residues of ancient organisms in the form of sedimentary rocks. A fossil can preserve the whole organism or one part of it like bones, shells, feathers, and leaves. Fossils are formed in many ways, but usually when a dead plant or animal in a watery environment and is submerged in mud and silt fossils formed. When soft tissues of an organism decompose it leaves the bones or shells behind and sediment builds on top and hardens into rock.
