Jurassic Period At the start of the Jurrasic Period,about 200 million years ago,the world began to change again. The climate became cooler and more plants grew. Dinosaurs became more and more common during the Jurrasic and there were lots of smaller reptiles too,such as lizards. There were insects,snails and spiders and the first birds appeared.

There were more kinds of dinosaurs than ever,as well as other reptiles such as snakes. Birds flew in the skies along with flying reptiles called pterosauraus. There were some small mammals.
