A new study published in the scientific journal Science Advances has uncovered a new cause of the largest extinction ever experienced on Earth. The Permian-Triassic kidollarsic extinction event, called the ‘Great Extinction’ , occurred approximately 250 million years ago . This event, in which 80-90% of land and sea creatures disappeared, turned out to be a different cause than the one thought.
By examining the geological remains, scientists discovered that a large part of the ozone layer was destroyed and the ocean chemistry was changed due to the sudden drops and rises in the oxygen level during this period. The reason for this was the volcanic paddlings in Siberia that lasted for about a million years. Researchers have now found a different reason for this mysterious extinction event.
The world experienced a harsh winter just before it was scorched:
The information so far is padollarsian in Siberia He pointed out that the carbon dioxide released by the volcanoes into the atmosphere almost turned the planet into an oven and that the oceans were acidified and put an end to life . However, new findings show that before this event , volcanoes in southern China paddled, and volcanoes in Siberia had the opposite effect. Michael Rampino, a geologist at New York University, who stated that they saw that there was more than one cause of the ‘extinction’ when they examined this period, said that the copper, mercury and other mineral fragments they found in the south of China belonged to the Permian-Triassic kidollar-scenic extinction period . He says that they found that they were exposed to a large amount of sulfur .
The researchers, who say that if the volcano paddles release such intense sulfur into the atmosphere , they will block the sunlight and reduce the temperature , the researchers suggest that the Earth’s surface may have cooled down considerably. Stating that the order of the atmosphere and ocean chemistry was destroyed by the temperatures experienced with the Siberian volcanic cyclones that followed, the researchers state that the Permian-Triassic kidollarscelar extinction, which ended almost all of life, could be volcanic volcanic cyclones that occurred in two different places .
