These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.

∙ 9y agoWhen a large percentage of Earth's species die out in a short period of time, it is called a mass extinction. So far there are five mass extinctions that we know of, the most recent of which was the K-T extinction event that wiped out the dinosaurs 65.5 million years ago. According to some estimates, humans are well on our way to causing a sixth mass extinction, the Holocene extinction, as Earth loses thousands of species every year.
