GEOLOGY

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 preserved fossil, also known as a “true form fossil, ” is one that remains intact, or nearly intact, because of the method in which it was fossilized.

Detailed explanation-3: -Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber, petrified wood, coal, hair, oil, and DNA remnants. There are five types of fossils: Body Fossils. Molecular Fossils.

Detailed explanation-4: -It is generally the hard parts of organisms that are preserved, e.g. their skeletons and shells, as these are stronger and more resistant. Therefore, it can be said that the fossil record is biased to organisms with hard parts.

Detailed explanation-5: -Fossils are the preserved remains or traces of animals, plants and other organisms from the remote past.
