The Mesozoic era is divided into three periods Triassic, Jurassic and Cretaceous.

During the early Triassic, corals appeared. Seed plants dominated the land, in the northern hemisphere, conifers flourished. Glossopteris was the dominant Southern Hemisphere tree during the Triassic period.

Many new dinosaurs appeared during the Jurassic period. Giant plant eating dinosaurs dominated the Earth. carnivores such as Allosaurus and Composognathus were plentiful. Many bird-like dinosaurs also thrived during this period.

The Cretaceous period saw the heyday of the dinosaurs. Many new species of dinosaurs evolved during this period. New dinosaurs such as, the deadly t-rex and the extremely large Giganotosaurus appeared for the first time as did Triceratops and many others.
