Ancient Earth Cores Upthe theory about life after dino-killing asteroid



In the journal Nature scientists have conveyed their surprise that these drilled cores "undermine a theory that utilisability at sites closest to the crater is due to environmental pollutants – such as toxic metals slowest. " triggered by the impact. "

First we want to go back to 66 million years ago: The asteroid strike, also known as the Cretaceous-Paleogene (K-PG) extinction event, ended the reign of the dinosaurs and killed most of the animals over 55 pounds – though crocodiles and leather-backed While the asteroid was estimated to be between six and nine miles across, it created a 93-mile-wide crater, which was eventually named after the 5,000-person city of Chicxulub, Mexico, a castle that is partially nearby The Yucatan Peninsula exists partially in the sea.

Scientists learned that the life in which the mega-asteroid landed came back only two to three years after its impact, which was a shock, and about 30,000 years later a thriving ecosystem had returned to the area around the crater, meanwhile it was in the Gulf of Mexico and farther out in the North Atlantic It took ten times as long for a thriving ecosystem to return there, an estimated 300,000 years.

"I find the most exciting result is that within just 30,000 years, we see the development of a healthy, high-productivity ecosystem in the crater," lead author Christopher Lowery, Ph.D. tells Inverse .

"Existing data suggested that ecosystems take longer to recover closer to the crater site, with locations in the Gulf of Mexico and the North Atlantic taking up to 300,000 years to return to the Cretaceous." [1
