What is permian extinction.

A study by Prof. Dan Rothman finds that increasing greenhouse gas emission rates could trigger a mass extinction in the ocean, reports Priya Shukla for Forbes. Shukla writes that Rothman found if a certain carbon threshold "is breached, it would take tens of thousands of years for the oceans to return to their original unperturbable state."The Permian-Triassic extinction event is the only mass extinction event that took a toll on the insect population, wiping them out in large numbers. Since so many species perished, the Permian-Triassic extinction event is also called, "The Great Dying".The most severe mass extinction event in the past 540 million years eliminated more than 90 percent of Earth's marine species and 75 percent of terrestrial species. Although scientists had ...We see the spikes in extinction rates marked as the five events: End Ordovician (444 million years ago; mya) Late Devonian (360 mya) End Permian (250 mya) End Triassic (200 mya) – many people mistake this as the event that killed off the dinosaurs.

The mass extinction occurred at what scientists call the Permian-Triassic Boundary. The mass extinction killed off much of the terrestrial and marine life before the rise of dinosaurs.

The End-Permian Mass Extinction (EPME) (also known as Permian-Triassic Mass Extinction, PTME) is one of the most studied geobiological events of the past.
