What Are Fossils?

Fossils are special remains or prints left by animals and plants that lived long ago. They can be bones, shells, or even footprints. Fossils help us learn about life from millions of years ago.

Fossils are found all over the world. Scientists called paleontologists study them to see how animals and plants have changed over time. Some fossils are very tiny, like microbes, and others are as big as dinosaurs.

Fun Facts About Fossils

Fossils can be made in many ways. Sometimes, an animal’s body gets covered in mud or sand. Over time, this turns into rock and keeps the shape of the animal. Other times, only a print or trace is left, like animal tracks.

People have found fossils for thousands of years. Long ago, some people thought fossils looked like dragon bones and used them for medicine. Today, we know better and study fossils to understand our planet’s history.

Fossils tell us stories about the past. They show us what the Earth looked like and what kinds of animals and plants lived there. By looking at fossils, scientists can even guess how old the Earth is!
