Dinosaurs flourished and dominated the earth for about 186 million years, during the Mesozoic Era. Dinosaurs went extinct at the end of the Mesozoic era and at the beginning of the Paleogene period, the first period of the Cenozoic Era. About 65.5 million years ago, a giant asteroid hit the earth in Mexico's Yucatan Peninsula. It is estimated that the asteroid had a 10 km diameter and was about the size of a small town. The asteroid hit our planet so strong that, after the impact, which was 2 million times more powerful than the most powerful explosive ever detonated by humans, it formed the Chicxulub crater. The ambient temperature immediately rose in some areas to as high as 1,480 degrees Celsius, which led to the burning of forests and of all things unprotected.
As a consequence, this affected herbivorous dinosaurs. A chain reaction ensued, with carnivorous predators also disappearing as their food supply dwindled.
Scientists consider the idea that a small percentage of dinosaurs survived this planetary cataclysm and their total disappearance was a slow process.
