Fossil Skulls and Teeth
• A fossil is any evidence of past life on our earth. • Fossils are very rare. This is because fossils only
form under the right circumstances. To become a fossil a plant or animals usually needs to have hard parts, such as bones, teeth, shells, or tough wood.
• The animal or plant must also be buried quickly to prevent it from decaying.
