On the basis of organism body preserved fossils are of following types :
1. Intact or entire or unalterated fossils : They are those type of fossil in which entire organism or part of their body is buried in the dry and cold region of the world. For eg : fossil of ancient elephant (mammoths) found in frozen ice of siberia. Insects embedded in amber.
2. Petrification or Petrified fossil : It is the type of fossil in which hard part of organism like teeth , skeltion, shells of mollusca , branches of trees etc remain preserved.
3. Mould or casts : They are those type of fossils in which impression of organism is only left bend. Even the skeletion devays leaving impression only which is the exact replica or copy of original organism.
4. Compression : It is the most usual type of plant fossil in which internal structure of plant is totally lost and thin carbon film giving outline of the plant is left behind.
5. Imprints or impression : It is formed due to footfrints of crawling worm or snail.
6. Pseudo fossil : It is false fossil which give impression but are not real fossil. For eg : In certain rocks , a structure are present which resembles the plant remain and are formed by crystallization of minerals found in crevices of rocks.
