The extinction of the Permits-Triassic was a mass extinction between the geological era of the Triassic and the Triassic of about 250 million years ago; it is the most fatal out of all extinctions on the earth It was something. Furthermore, during the extinction period of the Perm-Triassic, today's continent exists as a super continent called Pangea. This is the first time in history that continents or land exceed the ocean. It also happened before the Triassic dinosaurs roamed the earth. Meanwhile, animals such as telapida, synapses such as Pelicosaurus, insects, amphibians also occupied the earth.

These mass extinctions are fatal, but opened up the earth to create new forms of life. Dinosaurs appeared after the greatest extinction on the planet and the extinction of the Permian - Triassic was about 250 million years ago. The extinction of the largest species studied between the Cretaceous and the Paleogene three centuries ago about 65 million years killed the dinosaurs and provided mammals with space for rapid diversification and evolution. Scientists narrowed down some of the most likely sources of mass extinction. Events of flood basalt (volcanic eruption), asteroid collision, sea-level descent are the most likely cause of mass extinction, but other known events may also contribute. When the Earth's ocean loses oxygen - these include global warming, global cooling, methane eruption and anoxic cases

But can carbon sinks such as oceans be saturated with carbon? One of the theories here focuses on mass extinction of the Paleozoic era. Annihilation incident of 25 million years ago in the Triassic - Triassic. Due to this extinction, up to 96% of marine organisms and up to 70% of terrestrial vertebrates have been destroyed. There are several theories about the cause of extinction. "There is evidence that there is one or three different extinction pulses or phases.The latter suggested mechanisms include one or more large meteor impact events, large volcanic activities like Siberian traps, and the resulting coal and Including gas fires The greenhouse effect caused by the dissociation of methane inclusion complexes or the explosion by methanogenic microorganisms (called methanogenic bacteria), the sudden release of submarine methane is uncontrollable, changes in sea level , Increased hypoxia, increased drought, factors of climate change, etc. "
