  2. The First Dinosaurs • They appeared about 230 million years ago. • The dinosaurs were little meat-eaters and big plant-eaters. • This was the Triassic Period. • The Earth’s plates were all together and was called Pangaea.

  3. Gigantic Dinosaur • The giants were the sauropod, example of sauropods are : Brachiosaurus, Mamenchisaurus and Barosaurus. • Sauropods spent 18hour of their day eating. • Most of the sauropods lived in herds, to make it easier to find food and get away from trouble.

  4. The Deadly Meat Eating Dinosaurs • The largest meat eating dinosaurs were also the biggest land predator on earth. • Large meat-eaters lived in the late Triassic Period to the end of the Cretaceous Period which is also the end of the dinosaurs. • These carnivores killed their prey by rushing out of the trees or bushes or by scavenging on already dying or dead dinosaurs.

  5. How the Dinosaurs Became Extinct • The dinosaurs died out about 65 million years ago. • No one knows for sure how the dinosaurs died out. • There could be a meteorite that crashed into the earth and blocked out the sun. • Maybe many volcanoes erupted at the same time and made the dinosaurs die by causing disease.
