 1.) Petrified or Permineralized  2.) Cast  3.) Mold  4.) Carbon Film  5.) Trace  6.) Original Remains

 An organism is buried, and then each cell is replaced by minerals.

 The space left behind when a buried organism decays.

 An organism is buried and then decays, leaving a space in the sediment. This space is then filled in by rock in the exact shape of the organism.

Mold Cast

 A thin layer of carbon left behind when an organism is squeezed between layers of sediment.

 Evidence left behind by an organism such as trails, burrows, footprints, or feces.

 An organism is preserved in its original form without much decay or change. This can be in tar, amber, or ice.
