Extinction of Dinosaurs
Dinosaurs are one of the greatest wonders of the ancient world.The body of a dinosaur is so huge that even a giant elephant has been a huge challenge for scientists. Dinosaurs are an important stage in the evolution of life. When dinosaurs roamed the earth freely, humans did not even exist at that time, and if they had, not a single human would have survived in presence of dinosaurs. The dinosaurs were on earth about 225 million years ago. After that, the dinosaurs' empire continued undisturbed for about 160 million years, according to scientists. Then the ancestors of humans, i.e. animals with tails, may have originated. Present-day fully visible humans may have only appeared about 50,000 years ago.
