Fossils Tell Us About the Past

Long ago an animal died. It fell to the ground. Mud covered it. Over time, more mud
pressed down on it. After a very long time, its bones changed into rock. This rock is
called a fossil.

Many scientists look for fossils. They find them in very old rocks. Some fossils are
millions of years old. Many of the fossil animals and plants have died off. The only
way we know about them is by their fossils. Dinosaurs did not live at the same time as
humans. There are no drawings of them on cave walls. So in 1822, when the first
dinosaur fossil was found, people were amazed.

People are always digging for fossils. They find them all over the world. Fossils have
even been found in Antarctica. And new kinds of dinosaurs are still being discovered.
The people who dig for dinosaur bones can learn a lot about a dinosaur from its fossil.
They can look at the teeth and tell whether the dinosaur ate plants or meat. If it had flat
teeth, it ate plants. If it had pointed teeth, it ate other animals. But fossils cannot tell us
everything we’d like to know. For example, we are not sure that dinosaurs were reptiles.
We are not sure if they all laid eggs or if some had live babies. And because only their
bones are left, we may never know what colors the dinosaurs were.

1. Define the word "fossil."

2. How do fossils help scientist?

3. If you dug up a fossil, what would you do?
