Scientists earlier stated that asteroid collision led to the extinction of all the dinosaurs from Earth. According to a recent study, it has been revealed that had the asteroid hit just about anywhere else on the planet, the dinosaurs would have survived and would be still roaming the earth. That means the new research termed the dinosaurs ‘unlucky’ to be extinct from Earth.

The asteroid which was 6 miles wide crashed with Earth about 66 million years ago. The collision created a crater more than 110 miles across near what is now the town of Chicxulub in Mexico’s Yucatan Peninsula. The smacking of the asteroid with the Earth released a very high amount of energy, more than a billion times the energy released by the atomic bombs. It is believed that the intense crash wiped out all the dinosaurs from Earth, resulting in the death of more than 75 percent. Also according to the researchers, this Chicxulub asteroid impact would have resulted in a huge amount of ash soot and dust blocking the sunlight from reaching the Earth-almost up to 80 percent. Thus, the Earth would have faced rapid cooling resulting in” impact winter.”

Actually, large asteroid crash happens only once in every 100 million years, and according to the recent study, the Chicxulub asteroid had little more than a 1-in-10 chance of triggering a mass extinction when it stroked the Earth. The lead author of the study, Kunio Kaiho, a geochemist at Tohoku University in Sendai, Japan said that the probability of the mass extinction occurring was only 13 percent.

Co-author, Naga Oshima, an atmospheric chemist at Japan’s Meteorological Research Institute, said that sooth was the most lethal weapon that caused the extinction of Dinosaurs. When the asteroid hit the earth at Yucatan Peninsula in Mexico, it ignited the vast reservoirs of crude oil and hydrocarbons tucked beneath a shallow sea. This resulted in the burning of organic matters that created thick soot cloud at the stratosphere. As a result, sunlight got blocked, and plants died and simultaneously dinosaurs got killed.

After analyzing the computer simulated data regarding the amount of soot that asteroid impacts would have generated depending on the number of hydrocarbons in the ground, scientists found out that only 13 percent of the Earth’s surface would have sent high level of soot to the stratosphere. Kaiho informed that if the asteroid had hit a low- to medium-level hydrocarbon area on Earth, occupying approximately 87 percent of the Earth’s surface, mass extinction could not have occurred. So, it indicates that the dinosaurs might have survived the dangerous asteroid had it hit that 87 percent of earth’s surface and not the mere 13 percent high-risk area.
