There is a show in a museum in New York. It is about pterosaurs. Pterosaurs live 66 million years ago.

These animals can fly. However, they are not related to birds. They are related to dinosaurs. They are a unique group of animals. They are the biggest flying animals. Their wings are really big. One wing is around 5 metres long.

The animals have a backbone and they can fly. This makes them really special.

Difficult words: related to (like), wing (part of the body which makes the animal fly), backbone (line of bones in your back).

You can read the original story and watch the video in the Level 3 section.
