They Once Roamed Here

Millions of years ago, dinosaurs of all shapes and sizes roamed Earth. They went extinct 65 million years ago, but today scientists study their bones, fossils, and tracks to learn about how they lived. National parks (including one—Dinosaur National Monument—that takes its name from dinosaurs!) are home to many discoveries of these ancient creatures. Discover how national parks protect and study dinosaur fossils and how you can visit those sites.
