Great Dying was followed by more extinction
Recovery after the world\'s worst mass extinction, or \"Great Dying\" that occurred about 252 million years ago, was slowed by two other extinction events, says a study. The Earth has experienced five mass extinctions in its history that killed the majority of species living on the planet at the time.Â
New York: Recovery after the world's worst mass extinction, or "Great Dying" that occurred about 252 million years ago, was slowed by two other extinction events, says a study. The Earth has experienced five mass extinctions in its history that killed the majority of species living on the planet at the time.
The end-Permian extinction or "Great Dying" was the worst, with an estimated 95 per cent of marine life and 70 per cent of terrestrial life perishing.
The end-Permian extinction also had the longest recovery time of any mass extinction, lasting five million to eight million years.
In a paper, published in the journal PLOS ONE, the researchers studying marine fossil beds in Italy provide the first combined fossil and geochemical evidence for two distinct extinction events following the end-Permian that probably played a role in the slow recovery.
This study is a step toward understanding how life forms survived during the extinctions, which could help scientists understand how modern ocean life evolved and how it might respond to climate change in the future, said lead study author William Foster from The University of Texas in Austin in the US.
