Long, long ago before the era of dinosaurs started, the earth went on different kind of changes depending on the climatic and geographical changes. Before, all of the continents were joined together into one huge land mass called as Pangaea which was surrounded by a ocean of water called as Panthalassa. At the start of the terrestrial life, an era of formation of different kind of organisms and life on earth, the life of mammal like reptiles started. The appearance of dinosaurs started in the Mesozoic era which is almost 245 million years ago and the era is divided into three periods. Dinosaurs lived on with Triassic, Jurassic, and Cretaceous period. In the Cretaceous period due to a large change in the formation of earth, the life of many reptiles became extinct and its said that it was the start of the life of mammals.

Now, we cannot say pick up a firearm, shoot the other one Bang! and there the winner is, can we?, but they used many methods to fight. The carnivorous use teeth, claws, eyesight and smell, momentum, speed, bad breath (well most of all, did not use a tooth brush and a paste every morning but some of them had a more bad breath because of an infection by the accumulation of shreds of dead tissue) and some other herbivorous dinosaurs use tails, scales, bulk, camouflage, speed, hearing and some use horns, frills, crests, skulls.

Compared to others, these were the most smallest and lived only on eating plants. Instead of front teeth, they had a beak. They had rear legs which was largely used for running as they were the common prey for many carnivorous dinosaurs.

The end of dinosaurs has many reasons and nothing is of sure, according to different scientists. Though, the most stated reason is the crash of meteorite, causing an end for the cretaceous era. 65 million years ago, when a massive meteorite crashed into Mexico’s Yucatan Peninsula, which caused a rapid changes in the evolution of earth. But there are other theories as well stating that the extinction caused due to a major volcanic eruption in India over about 100,000 years ago, which was also a cause for global warming. Some also say the main reason is the climatic and biological effects which caused the extinction even before the meteorite crash and the volcanic eruptions.
