Discovering Dinosaurs

Finding Fossils How do we know dinosaurs lived on Earth? We know because we have found fossils in rocks all over the world.

Scientists have found fossils of dinosaur bones, footprints, teeth, nests, and eggs.

These scientists are carefully digging dinosaur fossils out of the ground. They will wrap up the fossils to keep them safe. Then they will take them to a museum.

At the museum, scientists will study the fossils. They try to fit bone fossils together to make a skeleton. Some pieces of the skeleton might be missing. Scientists use what they know about other animals to make pieces fit.

Learning from Fossils Scientists study other animals to learn about dinosaurs. Dinosaur bones may be bigger. But many are shaped the same.
