What is the Order of fossil preservation?

Fossils are preserved in two main ways: with and without alteration. Preservation with alteration includes carbonization, petrifaction , recrystallization and replacement. Preservation without alteration includes the use of molds and the collection of indirect evidence.

How are carbon fossils formed?

Carbon film fossils are formed from the carbon residue of a soft-bodied organism that has been buried in sediment.
