According to a new study, dinosaurs were obliterated by asteroids as powerful as 10 billion nuclear bombs from World War II

A 12-km wide asteroid targets Earth Hit 66 million years ago and extinguished 75% of life on the planet. This is evident from studies conducted by the University of Texas and published in the PNAS Journal. The event is believed to trigger forest fires over 900 miles away, triggering a devastating tsunami.

Many dinosaurs would have died that day, but others may have been killed by the ensuing atmospheric clashes. Scientists believe that the Earth has cooled dramatically after releasing sulfur into the atmosphere, blocking the sun and killing life.

The new investigation was based on rocks collected at the Chicxulub impact site off the coast of the Yucatan Peninsula in Mexico in 2016.

Professor Sean Gulick, who led the study, told CNN: "For me personally, the successful collection of seeds from the top ring of Chicxulub Crater was the result of years of writing proposals and plans that became reality.

" It It was a truly exciting moment when we first encountered the sediment from the impact itself and also realized that we saw events in such detail.

Gulick added that the project presents an unusual opportunity for geologists to read the "rock record" as 130 meters of rock in the Crater represents the events of the single day when the asteroid hit Rock represents every 1000 years.

Gulick and his team concluded from the abundance of sulphurous rocks near the crater and their absence that the asteroid must have vaporized any sulfu

They estimate that after the impact of the giant rock, 325 billion tons or more of sulfur was released into the atmosphere, four orders of magnitude more than the amount released by the Krakatoa outbreak in 1883 caused an average temperature drop of 2.2 degrees Fahrenheit for five years. [19659015]
