An article about fossils
At the beginning of the nineteenth century, the study of fossils began.
Before it began, people did not believe that fossils once lived.
The most famous fossils of all are the dinosaurs. Now, of course, there are no
Dinosaurs. They all died millions of years before people lived in the world.
Scientists still do not know why the dinosaurs died.
Many scientists believe that dinosaurs died after a change of climate.
The earth got cold, and many plants and animals died.
The British scientist Richard Owen invented the word dinosaurs 150 years ago. He used two Greek words, deinos and sauros, meaning terrible lizards.
Some dinosaurs could run rapidly on two legs .Other had horns to protect them. Some dinosaurs ate plants, for example triceratops and stegosaurus.
Other ate meat, like the giant tyrannosaurus, which stood up to seven metres high.
