This event marked the border between the Permian and Triassic geological periods, and is known as the Permo-Triassic extinction event, or P-T event for short.

The ecoPT project involves 22 researchers from across the UK and China, who are collaborating to examine not only what caused the P-T ...Extinction Event: An extinction event is a phenomenon where a substantial amount of species went extinct at a rapid space. Based on the amount of life wiped out, an extinction event can be categorized as either a major or minor extinction event.The end-Permian extinction probably isn't as well known as the Cretaceous extinction that wiped out the dinosaurs some 65 million years ago.

Although this event was less devastating than its counterpart at the end of the Permian Period, which occurred roughly 50 million years earlier and eliminated more than 95 percent of marine species and more than 70 percent of terrestrial ones (see Permian extinction), it did result in drastic reductions of some living populations.The end-Triassic extinction particularly affected the ammonoids ...The Triassic period was the first period of the Mesozoic era and occurred between 251.9 million and 201.3 million years ago.

The therapsida were radiation from synapsids as a new clan in the late Permian. These were the subset of synapsids that survived the Permian extinction. Only 3 main clades of therapsids survived: dicynodont anomodonts, therocephalians, and cynodonts. Ultimately, only cynodonts survived extinction and competition in the Triassic period, giving rise eventually to extant mammals.The end-Permian mass extinction was the most severe biodiversity crisis in Earth history. To better constrain the timing, and ultimately the causes of this event, we collected a suite of geochronologic, isotopic, and biostratigraphic data on several well-preserved sedimentary sections in South China.The Permian-Triassic extinction killed off so much of life on Earth that it is also known as the Great Dying.
