Sedimentary rock is a rock that is formed by the compaction of sediments with the effect of heat and pressure inside the earth crust. These rocks are responsible for preserving fossils of dead animals and plants. When an organisms dies, the carcass decomposed by the decomposers present in the soil. The hard parts remains undecayed like wood, leaves, shells, bones and other skeleton remains. These remains are covered by the piles of sediments formed sedimentary rocks after compaction. A carbon film is the trace of organic matter that forms the replica of the animal or plant structure over another structure like rock. Sedimentary rock will provide a adequate pressure on the body of the organism, will result in formation of a carbon film of  a leaf preserved insect.
