The Permian-Triassic extinction, aka the Great Dying, eradicated more than 90 percent of earth’s marine species and 75 percent of terrestrial species 252 million years ago. It was the deadliest mass extinction event in the history of our planet, and its legacy lives on in the flora and fauna of the modern world.According to National Geographic, the Earth began with a cataclysmic event called the big bang. The BBC states that there have been five major cataclysmic events that caused mass extinctions in the recorded history of the Earth.
