Science FOSSILS GP3

1. Materials that can trap living things and cause the formation of fossils:

• tar pits

• extinct

• sap and ice

Areas filled with sticky material that seeps to Earth’s surface from inside Earth:

• tar pits

• extinct

• sap and ice

Organisms that no longer live on Earth:

• tar pits

• extinct

• sap and ice

1st. step to form a fossil

• After millions of years land changes and exposes the layers that contain the bones and footprints.

• Minerals enter the mold and harden over many years.

• Water flows through the rock and dissolves the remains of the animal. The space left behind is a fossil mold.

• The body is quickly covered with layers of mud or sand.

• An animal dies in the ocean. Its body sinks to the floor.

2nd. step to form a fossil

• Water flows through the rock and dissolves the remains of the animal. The space left behind is a fossil mold.

• Minerals enter the mold and harden over many years.

• An animal dies in the ocean. Its body sinks to the floor.

3rd. step to form a fossil

• After millions of years land changes and exposes the layers that contain the bones and footprints.

• The body is quickly covered with layers of mud or sand.

• Water flows through the rock and dissolves the remains of the animal. The space left behind is a fossil mold.

• Minerals enter the mold and harden over many years.

• An animal dies in the ocean. Its body sinks to the floor.

4th. step to form a fossil
