GENERAL GEOLOGY

Detailed explanation-1: -Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.

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.
