Most people know that dinosaurs went to extinction after a huge asteroid has impacted the earth, resulting in the Earth's climate change that killed the huge reptilians. However, a new study has suggested that the size of the rock may not be the reason of the huge destruction but the spot where it hit the planet.

In an article published in Yahoo, scientists have studied rock samples 1,300 meters beneath the Gulf of Mexico. With this, they were able to get a great look at what the area would look like at the time when the asteroid that killed the dinosaurs struck.

When the rock slammed the Eath 66 million years ago, the area was more than a shallow sea, the scientists believe. They also now believe that the collision sent a great amount of sulphur skyward, which ultimately destroyed the planet, killed the dinosaurs, and having the Earth to the Ice Age period in which the lumbering prehistoric dinosaurs could not endure.

In an article published in BGR by Mike Whener, the researchers suggested that if the killer asteroid had made a watery splashdown in the middle of the huge Atlantic or the Pacific Ocean, the impact would have been less severe to the dinosaurs. They said that the deadly severe asteroid that blotted out the sun in the days could have hit the ocean and prehistoric plants and animals would have survived. In addition, they said that the food chain would not be messed up and would stay intact. But of course, if that happened, there are low chances that humans would live.

The full documentation of scientists about the asteroid that hit the dinosaurs would be presented in the new BBC documentary called "The Day The Dinosaurs Died". It would also feature new studies about the dinosaur and how did they live in the prehistoric era.
