Detailed explanation-1: -The word fossil is derived from the Latin fossilis meaning ‘unearthed’. Preserved evidence of the body parts of ancient animals, plants and other life forms are called ‘body fossils’. ‘Trace fossils’ are the evidence left by organisms in sediment, such as footprints, burrows and plant roots.

Detailed explanation-2: -A fossil is any evidence of prehistoric life (plant or animal) that is at least 10, 000 years old. The most common fossils are bones and teeth, but fossils of footprints and skin impressions exist as well.

Detailed explanation-3: -A Fossil is any preserved remains, impression, or trace of any dead organism which was living in the past from a different geological age. Examples of these could be bones, stone imprints of animals or microbes, exoskeletons, shells, objects preserved in petrified wood, oil, coal, and DNA remnants.

Detailed explanation-4: -fossil, remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in Earth’s crust.

Detailed explanation-5: -For an organism to be fossilized, the remains usually need to be covered by sediment soon after death. Sediment can include the sandy seafloor, lava, and even sticky tar. Over time, minerals in the sediment seep into the remains. The remains become fossilized.
