Scientists were able to trace the dinosaur-killing asteroid that wiped the gargantuan animals off the face of the planet about 60 million years ago. A new study reveals that the catastrophic phenomenon at the time was also responsible for the annihilation of several marine lives in Antarctica.
All this time, scientists were of the notion that creatures living in the South Pole managed to survive the mass extinction in the aftermath of the impact. Nevertheless, new studies conducted by a group of scientists at the University of Leeds and the British Antarctica Survey on Seymour Island in Antarctica Peninsula revealed that their testing confirmed the age of 6,000 marine fossils discovered from the poles, which date back to 65 and 69 million years ago.
A report compiled by the University of Leeds that was recently published in the Journal of Nature Communications on Thursday draws the conclusion that marine creatures at the Earth’s Polar Regions were badly impacted.
A study shows that 70% of the world’s animals were obliterated almost at the same time in Antarctica when dinosaurs suddenly became extinct, suggesting that the deaths of the creatures were sudden and extensive, notes CNN.
In an interview to the press, James Witts, a doctorate at the University of Leeds and a lead author of the study, said, “Our research essentially shows that one day everything was fine—the Antarctic had a thriving and diverse marine community—and the next, it wasn’t.”
The Inquisitr points out that the study effectively settles the long-running debate about the impact of the asteroid on Earth. The mass death that took place 65 million years ago was not just restricted to the dinosaurs, but fatally impacted other creatures too.
Putting a stop to controversies surrounding the annihilation of other creatures billions of years ago, Witt said, “This is the strongest evidence from fossils that the main driver of this extinction event was the after-effects of a huge asteroid impact, rather than a slower decline caused by natural changes to the climate or by severe volcanism stressing global environments.”
