GEOLOGY

Detailed explanation-1: -Carbonization is a type of fossil preservation in which the organism is preserved as a residual, thin film of carbon instead of the original organic matter.

Detailed explanation-2: -Carbon Films A thin film of carbon residue is left, forming a silhouette of the original organism called a carbon film.

Detailed explanation-3: -A carbonaceous film or carbon film is an organism outline of a fossil. It is a type of fossil found in any rock when organic material is compressed, leaving only a carbon residue or film.

Detailed explanation-4: -Petrified or permineralized fossils are fossils in which minerals replace all or part of an organism, thus making them rock-like. Another type of fossil is a carbonized fossil which is sometimes called a carbon film, because it is an extremely thin coating of carbon on rock.

Detailed explanation-5: -Carbon films form when some carbon is still left over when an organism is buried under sediment. A film of carbon still remains. Preserved remains are also called fossils.
