There have been at least ten such events. , including the Mount Everest-sized asteroid that crashed into what is now Mexico 185 million years ago and wiped out most dinosaurs <onlyinclude> This list of dinosaurs is a comprehensive listing of all genera that have ever been included in the superorder Dinosauria, excluding class Aves (birds, both living and those known only from fossils) and purely vernacular terms. . He pinpoints disease as another culprit in extinctions of certain groups of animals. For example, canine-distemper virus is now believed to have killed 70 percent of all Baikal seals. People, however, have been the creature with the most effect on others, Ellis argues. Over-hunting and human-driven degradation of the environment are two key reasons for the decline in modern species, he writes.
