A huge build up of volcanic activity around 65 million years ago could have produced such large eruptions that caused plants and animals to be burned by lava, choke on ash or just die of starvation as the food sources were being destroyed. Smaller creatures that were able to crawl under ground or fly away did. Also lose that could swim under water for a while were able to escaped to flames. Larger mammals such as the dinosaurs were not that lucky. Those creatures that did survive adapted to their new environments and are recognizable as some of the animals we see today such as birds and crocodiles.

There are a number of theories which explain the extinction of dinosaurs. One theory says that this happened because of the changes in the climate of the earth. One theory suggests that dinosaurs extincted because of diseases which was a contagious and epidemic disease, which finished all of the dinosaurs in the world. The major theory which explains extinction of dinosaurs is known as Asteroid Theory. Asteroid theory suggests that a huge comet collided with earth almost 65 millions years ago. This created dust in the atmosphere and as a result, sunlight did not reach the other. This damaged the plants and animals on the earth. As a result dinosaurs extincted from the earth crust.
