Fossils are the preserved remains or traces of organisms that lived long ago. Dinosaurs are some of the most famous fossil organisms that scientists study today. These ancient reptiles lived millions of years before humans existed, and fossils are the only way we can learn about them.

Dinosaur fossils come in many different forms. Paleontologists—scientists who study fossils—have found dinosaur bones, teeth, claws, and eggs buried in rock layers. They have even discovered trace fossils, which are evidence of dinosaur activity rather than body parts. Footprints pressed into ancient mud and later turned to stone are examples of trace fossils. These footprints can show how dinosaurs walked and how fast they moved.

Scientists have found dinosaur fossils on every continent, including Antarctica. This tells us that dinosaurs lived all over the world. By carefully studying dinosaur bones, paleontologists can figure out how big a dinosaur was, what it ate, and how it moved. For example, sharp teeth suggest a dinosaur ate meat, while flat teeth indicate it ate plants. Long leg bones show that some dinosaurs could run quickly.

The last dinosaurs went extinct—meaning they all died out—about 66 million years ago. Dinosaur fossils prove that very different kinds of animals lived on Earth long before humans appeared. They help us understand how life on our planet has changed over time.

Interesting Fact: The largest dinosaur footprint ever found measures over 5 feet long! It belonged to a giant plant-eating dinosaur that lived in Australia about 130 million years ago.
