This dangerous cat lived thousands of years ago in America. It had two very big teeth that it used to kill animals. You could see these teeth even when its mouth was closed. People think that this cat could kill very big animals. It was extinct around 10, 000 BCE because there wasn’t enough food for it.

This big animal lived in the middle of Europe and Asia until about 8, 000 BCE. It had two horns—the big one could be one metre long. It had a thick woolly coat to keep warm in the cold winters. But then the weather changed a lot and the woolly rhinoceros couldn’t live in the warm weather. Also, many people killed them for food. So they died out.

The dodo was a bird. It lived on the island of Mauritius. Once there were thousands of them on the island. Then people from Europe arrived and started to eat them. The Europeans took animals such as dogs and cats to the island, and the animals ate the dodo eggs. Why didn’t the dodo fly away from the people? Because it couldn’t fly. In 1681, it became extinct.
