About Fossils
- A fossil begins as a creature that dies and falls into mud or sand.
- Over millions of years the mud or sand turns into a rock with the creature trapped inside.
- The creature is replaced by minerals leaving a rock that is the same shape as the creature.
- In animals it is usually only the bone that becomes a fossil.
