Diversity dynamics of the Permian-Triassic land plants in South China are studied by analyzing paleobotanical data. Our results indicate that the total diversity of land-plant megafossil genera and species across the Permian/Triassic boundary (PTB) of South China underwent a progressive decline from the early Late Permian (Wuchiapingian) to the Early-Middle Triassic.The Permian-Triassic mass extinction, around 252 million years ago and also known as the "Great Dying," is the worst ever to affect Earth.

The scientific consensus is that the main cause of extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [19] which released sulfur dioxide and carbon dioxide, resulting in euxinia and anoxia, [20] [21] elevating global temperatures, [22] [23] [24] and acidifying the oceans.But about 250 million years ago, the Permian period ended with a rapid mass extinction.Something happened that wiped out 75 percent of the land animals and over 95 percent of ocean life.The Permian extinction saw the loss of 80 to 96 percent of all marine species. In the Cretaceous event, perhaps 60 to 75 percent of marine species disappeared. What caused these immense die-offs ...

They remove large numbers of species, genera and families, and in varying degrees destroy both marine and terrestrial ecosystems and reset the planet's evolutionary agenda (Jablonski, 1991).Five mass extinctions characterize the Phanerozoic, the end Ordovician, Late Devonian, end Permian, end Triassic and end Cretaceous.The causes of this extinction are poorly understood. The end-Permian extinction (also called P/T or Permian/Triassic) was the largest recorded extinction event so far in the history of life, with an estimated 96 percent of all marine species and 70 percent of all terrestrial species lost. bloodshed in kansas Mass extinction. The greatest mass extinction episodes in Earth’s history occurred in the latter part of the Permian Period.Although much debate surrounds the timing of the Permian mass extinction, most scientists agree that the episode profoundly affected life on Earth by eliminating about half of all families, some 95 percent of marine species (nearly wiping out brachiopods and corals ... The end-Permian mass extinction event of roughly 252 million years ago – the worst such event in earth’s history – has been linked to vast volcanic emissions of greenhouse gases, a major temperature increase, and the loss of almost every species in the oceans and on land.
