Toward the close of the Permian Period, the largest mass extinction in Earth's history took place. Pangea Summary. Pangea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 ...According to Discovery, there are many theories as to why the woolly mammoth became extinct, from disease and hunting to some sort of natural catastrophe. However, evidence has come to light that climate change may have been the real culpri...These emissions may have caused atmospheric pCO 2 to rise to >8000 ppm during the end-Permian mass extinction (Davydov et al., 2021). The release of greenhouse gases, augmented by the positive climate feedback of melting permafrost, is the probable cause of the large negative δ 13 C excursion during the PTTI (Joachimski et al., 2019).The Permian mass extinction unfolded during tens of thousands of years and was not the sudden die-off that an asteroid impact might cause, the researchers said.

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 has largely gone unnoticed due to the sponges' size and the ...New research from the University of Washington and Stanford University combines models of ocean conditions and animal metabolism with published lab data and …

Researchers have long suspected a space rock might have been involved. Some scientists have blamed ...The Permian mass extinction, which happened 250 million years ago, was the largest and most devastating event of the five. The Permian-Triassic extinction event is also known as the Great Dying. It eradicated more than 95% of all species, including most of the vertebrates which had begun to evolve by this time. Some scientists think Earth was ...

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.

One lineage of crinoids survived, but never again would they dominate the marine environment. Paleozoic fossil localities

By the end of the extinction, just one genus of these apex creatures survived, but surprisingly, it flourished. Lystrosaurus — a "disaster taxon," or an organism that thrives in conditions that are lethal for most species — is "the poster child of the end-Permian extinction," says Pia Viglietti, a paleontologist with the Field Museum of Natural History in Chicago.But pinpointing the cause of the extinction requires better measurements of how long the extinction period lasted. Now researchers at MIT have determined that the end-Permian extinction occurred over 60,000 years, give or take 48,000 years — practically instantaneous, from a geologic perspective. The new timescale is based on more precise ...
