For now, they know that the asteroid's impact was so powerful caused material to fly into orbit and fall back into Earth like fireballs. Later, ash covered the skies, turning the planet into a dark and cold place.

"This created a chain of extinction. Months later, the dust fell on the continents and oceans, changing the chemistry of the oceans," said expedition chief Jaime Urrutia, president of the Mexican Science Academy.

While there are still debates about whether the asteroid is solely to blame for the disappearance of dinosaurs, scientists agree that it caused great destruction and had a role in how life evolved after its crash.http://phys.org/news/2016-05-sea-scientists-drill-crater-dino.html?utm_source=nwletter&utm_medium=email&utm_campaign=daily-nwletter
