A pior extinção em massa da história da Terra aconteceu há cerca de 252 milhões de anos. Conhecida como Grande Mortandade ou Extinção do Permiano-Triássico, ela eliminou até 90% das espécies animais marinhas. Vulcanismo gigantesco, aquecimento extremo e oceanos pobres em oxigênio estão entre as principais causas investigadas. Mas fica a pergunta: foi o vulcanismo o grande responsável ou um asteroide também teve participação?#dinosaurios#prehistoria#extincao#paleontologia
