The main cause of the mass extinction of Life on Earth 252 million years ago.

According to foreign media reports, the Sycity University website published a message that the university geologists concluded that the Siberian Tingus River basin, a large amount of magma on the surface is nearly 252 million years ago, the main cause of the mass extinction of life on Earth.
more than 95 percent of marine life and 70 percent of land life disappeared from the earth at that time.
July 13, 2016 local time, researchers introduced to the public the fossils of the orc-footed sub-dinosaur they found in Argentina, which they found had a short forebear different from the dragon.
the dinosaur was about 20 feet tall or taller, while its fore limbs were only 2 feet long and each had only two fingers. Seth Burgess, one of the
project's researchers and an expert with the US Geological Survey, said: "There have been five mass extinctions since life appeared on Earth more than 600 million years ago, mostly related to volcanic eruptions and asteroid impacts on Earth.
re-analysis of the link between magma motion, climate change and the disappearance of organisms, a model has been created that could explain the causes of the Great Extinction of the Second Superacontines.
" American geologists studied Siberian trapezoidal rocks formed by magma, where intense volcanic activity took place.
large amounts of lava, ash and gas from a large, wide, flat volcano, raising concentrations of sulfur dioxide, carbon dioxide and methane in the atmosphere to dangerous levels.
this history was previously well known, but scientists previously agreed that the process was gradual, meaning it was not likely to lead to mass extinction.
but U.S. geologists studied Siberian keystones and concluded that there had been a short magma eruption interval at the beginning of the volcanic season, which was the main cause of the disaster.
, May 26, 2016, in Saint-Denis, France, the Piton de la Fournaise volcano erupted, spewing magma.
of this phenomenon is that magma does not immediately flow to the surface, but flows between underground rocks.
, sedimentary rocks such as limestone, chalk and charcoal are heating up sharply on the surface.
scientists believe that the two superimposed to cause a large number of greenhouse gas emissions, global warming.
