The fall of Triassic Period 

 One Earth, one continent, but a lot of things happened during this period. 

There was just one landmass, then stretched from pole to pole and included a vast desert at its centre. There was no grass, but that period was magical for it witnessed a lot of things. 

Dinosaurs were the greatest success story of the Triassic but another group of animals was beginning to emerge, too. However, an extinction again occurred. Geologists are still currently unraveling what caused the extinction that once again killed a large numbers of sea and land animals. Although, the effects were said to be less dramatic than the first wiped-out just before the Triassic Period opened. However, with the evolution of dinosaurs, this period successfully made a mark not only in the geologic time scale but also in Hollywood movies.
