1. What happened on the "Dinosaurs' bad day"? What was the effect of this?

On that day, the Yucatan Peninsula was hit by a huge 6-mile-wide asteroid.

Explanation:

Dinosaurs belong to a large fitted Dinosaur community of reptiles. They emerged just before the Triassic years from 243 to 233.23 million years ago, while actively researching was undertaken on the precise origin and time of the evolution of dinosaurs.

The result was that sufficient Earth was thrown into the atmosphere and sufficient dust was produced to reflect sunlight completely as well as the earth was filled of flames. The crater islet was about 200 miles across and about 75% of the Earth's biodiversity were wiped out.

Scientists reveal that 66 million years ago, the comet of Chicxulub washed out dinosaurs. Nevertheless, researchers have still been told of this case, which has altered the course of the great creatures on earth. New evidence suggests that after the asteroid hit this planet, earth turned cold.
