The Permian–Triassic boundary (PTB, ~252 Ma) crisis was the most severe mass extinction episode in Earth history.

Around the time of the end-Permian extinctio Earth’s most severe mass extinction, the “Great Dying,” began 251.94 million years ago at the end of the Permian period, with the loss of more than 90% of marine species. Within the tropical shallow-water marine communities, signific A sudden change in depositional conditions is thought to have occurred at the Paleozoic-Mesozoic boundary in the main Karoo Basin due to episodic, but pronounced tectonic uplift of the southeasterly source area as well as rapid climatic warming initiated by the end-Permian extinction event (Smith and Ward, 2001). Scientists call it the Permian-Triassic exti

The end-Permian mass extinction was the most severe biotic crisis in Earth’s history. In its direct aftermath, microbial communities were abundant on shallow-marine shelves around the Tethys. They colonized the space left vacant after the dramatic decline of skeletal metazoans. The presence of sponges and sponge microbial bioherms …At the end of the Permian, conditions became unsuitable for most life and about 95% of marine species were eliminated as well as 70% of terrestrial species in a very short period of time, in geologic terms.Reconstruction came to an end as a direct result of too many Southerners opposing the reconstruction.The Great Permian Extinction: When all life on Earth almost vanished.
