🌟 Plant-eating giants

The biggest dinosaurs ate plants, like Diplodocus and Brachiosaurus, with very long necks to reach leaves high in the trees.

🔍 Scary hunters

Some dinosaurs ate meat, like Tyrannosaurus rex, with big teeth as sharp as knives, walking on its strong back legs.

💡 How do we know about them?

No one has ever seen a living dinosaur! But scientists have found their bones, eggs and footprints turned to stone in rocks, and from these they learned their shapes, sizes and ways of life.

🎯 Where did they go?

Dinosaurs died out about 66 million years ago. Scientists think a huge rock from space hit the Earth and changed the climate a lot. But the birds we see today are relatives of the dinosaurs!
