THE MASS EXTINCTION OF THE PERMIAN ~250 million years

 

The Permian–Triassic (P–Tr) extinction event, informally known as the Great Dying, was an extinction event that occurred 251.4 million years ago, forming the boundary between the Permian and Triassic geologic periods . It was the Earth's most severe extinction event, with up to 96 percent of all marine species and 70 percent of terrestrial vertebrate species becoming extinct; it is the only known mass extinction of insects. Fifty-seven percent of all families and 83% of all genera were killed off. Because so much biodiversity was lost, the recovery of life on earth took significantly longer than after other extinction events. (click to see all the article on Wikipedia)

二疊紀大滅絕 ~25千萬年前

二疊紀-三疊紀大滅絕,非正式的說法稱為大滅絕,發生在25140萬年前,二疊紀與三疊紀之間。這是地球上最為嚴重的滅絕事件,高達96%的海洋生物物種及70%的陸地脊椎動物物種滅絕了,而且這是唯一一次昆蟲遭大量滅絕的紀錄。57%的科和83%的屬消失了。因為如此多的物種滅絕,物種回復的時間比其他的滅絕事件都來的久。
