Dinosaurs are believed to be disappeared around 65 million years ago by the end of the cretaceous period. They are believed to have survived for nearly 165 million years on earth.

Theories behind the disappearance of dinosaurs:

• Intense volcanic eruptions: Scientists and palaeontologists believe that frequent volcanic eruptions that resulted in extreme temperature rises can be a reason behind the sudden disappearance of dinosaurs.
• Asteroid showers: It is also believed that huge asteroids fall upon earth resulting in the mass destruction of dinosaurs.
• Climate change: The sudden mass extinction of dinosaurs can also be due to drastic climate changes like thunderstorms, extreme chilling winters.
