marishachu [46]
<h3><u>Processes that form different fossil types:</u></h3>
  • The remained parts and elements of an organism that live several years ago is called as fossils.
  • Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.
  • Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.
  • Carbonization is the chemical reaction forming the thin film of carbon of the organic material.
  • Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
