When an organism is quickly buried and flattened by enormous pressure and only the carbon from the organism remains as a thin black film.

• mold and cast
• carbonized
• trace
• tar pit fossil

A record of the activity of an organism such as footprint or scratches.

• mold and cast

• trace

• frozen

• preserved in amber

When an organism's tissues are replaced by minerals from water and form a hard, 3-D copy of the original.

• mold and cast

• carbonized

NGSS.MS-LS4-1

When an organism gets stuck in tree sap which hardened over time

• permineralized

• trace

• preserved in tar

• preserved in amber

An impression of an organism's body shape is left in sediment. This impression is then filled with minerals in water which hardens.

• frozen

• preserved in amber

• mold and cast

NGSS.MS-LS4-1

This preserves much of the organism, including the organs and genetic material. It occurs when an organism becomes trapped, dies and is quickly frozen.

• mold and cast

• frozen

• permineralized

• trace

This sticky, thick liquid traps organisms and preserves its hard parts while dissolving the soft body parts.

• carbonized

• mold and cast

• preserved in amber

• preserved in a tar pit
