PTEROSAURS

Pterosaurs means flying lizard. They lived about 230 years ago.

Pterosaurs had large brains and fur-covered bodies .They also had hands .Three fingers were claws ,but,the long fourth finger was part of the wing. They had light ,hallow bones ,like those of birds.

The Quetzalcoatlus was huge pterosaur with a wingspan of up to 13 metres.It was the largest flying creature ever, and the last of the pterosaurs.It's weight was only about 100 kg becaus its bones were light.

T-REX

A close relative of Albertosaurus, king of the tyrant lizards Tyrannosaurus rex was one of the amazing dinosaurs to ever live. The largest known meat eater, it was more than 12 metres (37 ft) long and stood almost as tall as a giraffe. Unlike a giraffe, however, Tyrannosaurus rex was massive and powerful.
Its skull in particular was an imposing unit of bone. Up to 60 teeth, some of them longer than a human hand, lined its jaws. If humans had been around, they could have slid down its gullet with ease. Its eyes faced forward, providing better depth perception, important for a predatory animal, and its narrowed snout gave it a clear field of vision. At the other end, a heavy tail counterbalanced the skull. A complete tail has never been found, so no one knows exactly how long it might have grown.
Tyrannosaurus rex is one of the most famous of the extinct reptiles.
