Dinosaurs (lived)  on our planet 65,000,000 years ago! The first dinosaurs (looked) like big lizards. Many of them had short tails, big heads (and)

walked on four legs. Most dinosaurs were herbivores, which means that they only ate plants. Some of these dinosaurs were very (small) but other kinds of dinosaur were bigger and heavier and were carnivores, which means that they ate meat. Dinosaurs lived (in) warm forests where there were lots and lots (of) plants and water. But about 60,000,000 years ago, some people say (the) weather on Earth suddenly got colder and drier. Many plants (that) dinosaurs liked to eat stopped growing, which was a terrible problem for these animals, so soon dinosaurs disappeared too.

Today, people sometimes (find) dinosaur teeth in rocks or under the ground. Dinosaurs are now extinct, but you can learn about (them) in special science museums or when you watch scary dinosaur films (on) TV.
