Volcanic eruption linked to unrecorded mass extinction from about 233 million years ago

Even though re have been only five widely-accepted major mass extinctions, a recent study has suggested possibility of a new mass extinction that created conditions favourable for disaurs to flourish on Earth.

A study published earlier this month in Science vances has proposed that a previously unkwn mass extinction h occurred at least 233 million years ago, during Carnian Pluvial Episode (CPE).

Citing field studies, researchers have said that large volcanic eruptions that occurred in western Cana are likely to have caused event by releasing excessive amounts of greenhouse gases.

Scientists believe this furr led to global warming followed by a period of increased rainfall that went on roughly for one million years and shortly after, climatic conditions changed from being rainy to arid that coupled with a surge in plant growth and provided a warmer, oxygen-rich environment that was habitable for disaurs. 

researchers wrote, “We show that existing data indicate that CPE was a major extinction event that was followed by an explosive diversification of important organisms in sea and on land that w play a key role in modern ecosystems.”

NYU geologist opposes CPE as major mass extinction

Earlier in 2019, a geologist at New York University, Dr Michael Rampi, h published a paper suggesting a different mass extinction 260 million years ago dismissing CPE as t meeting criteria for such an event.  A major mass extinction event is accepted to have taken place when at least 75 percent of species in world die within a relatively short period of time.

Even though it is difficult for researchers to gar data backing potential of such an event, in past 545 million years, re have only been five of se mass extinctions that were majorly triggered by volcanic eruptions. re have been many mir mass extinctions throughout Earth’s history that led to disappearance of 20 to 40 percent of species.
