# pterosaur

noun (a pterosaur, pterosaurs)

«pterosaur» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

A pterosaur was a flying reptile that lived at the time of the dinosaurs, with wings of skin stretched from a very long finger. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/P/pterosaur/#m1)

### In the lessons

In science and history lessons, pterosaurs like Pteranodon and Quetzalcoatlus flew over the dinosaurs; some were as big as a small plane. They are not dinosaurs and not birds — they are close cousins of dinosaurs. They died out with the dinosaurs.

### Examples

The «p» is silent: «TERR-uh-sor». Common trap: calling them «flying dinosaurs». Birds came from dinosaurs; pterosaurs did not become birds.
