Over 250 Million years ago an unexpected events happen that made the planet earth to transform radically. This event is known as the Permian Triassic Mass Extinction or also called by many the Great Dying. This mass extinction is known as the worst extinction comparing them to the Ordovician, Devonian and the Cretaceous Extinction. Some individuals are not award that the Permian –Triassic are two forming boundary between the end of the Permian and the beginning of the Triassic period. The Permian-Triassic Extinction almost killed the whole Earth. Since this extinction took place so long ago it had for scientists to gather all the information that made this extinction to happened. During the time of Permian period Main species were the Therapsids like the Ducynodon and

They were mammal-like reptiles, they are describing as small to medium sized animals. Occurring to some paleontologists they believe that Therapsids were cover with fur. Some of the characteristics were fewer bones in the skull and enlarged lower jawbones. Scientist think that Therapsids “were endothermic or warm blooded, enabling the to maintain a constant internal body temperature.” (Chapter 13) this helps them expand any habitats. But everything was about to be exterminated. The event of Permian-Triassic exterminated 79 percent of the life on land. this would include the pareiasaurs, reptiles, dinocephalian and many more. over 96 percent of the marine species. The fusulinids, rugose and trbulate corals, and brachiopod orders and many more did not survive during the end of Permian period. A large percent of insects were also extinct with the extermination. But during the Triassic period the some plant survived like the gymnosperm as well as the
