The Permian extinction happened in at least two main phases, one in the Guadalupian and the other near the end of the Lopingian, and in each phase different animal and plant groups became extinct diachronously, phasing out according to the degree they were influenced by the developing anoxia within the Paleo-Tethys.A meteor strike on the Yucatan peninsula in Mexico led to the disappearance of dinosaurs millions of years ago.
