Jurassic world

Early in the Jurassic period, the herbivours dinosaurs were mainly prosauropods and small ornithopods. By the late Jurassic, herds of giant sauropods roamed the land. These dinosaurs,as well as other reptiles and mummals, fed on the lush plant life.
The first birds appeared, but  the pterosaurus remained the rules of the skies.
