Fossilized imprint or impression of an organism. Sediment hardens around the organism, as the organism decays all that is left is the impression and the sediment eventually turns to rock.

• Preserved Remains/Original Remains

• Trace Fossil

• Mineral Replacement/ Mineralization

• Cast

• Mold

Fossilized traces of an animal's movement or activity. Includes, tracks, footprints, and nests. These help scientists learn about an animal's characteristics or behaviors.
