Fossil Types

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.

• Preserved Remains/Original Remains

• Carbon Film/ Carbonization

• Trace Fossil

• Cast

• Mold
