The Mesozoic period began about 250 million years ago when the Permian-Triassic extinction occurred, probably by a combination of gradual atmosphere change and some external event like an Earth impact. The period ended about 66 million years ago with another great extinction, this one probably a combination of an impact and volcanic activity.
