The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
The Permian-Triassic extinction event (the Great Dying, the 'mother of mass extinctions').
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.

The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.

It ended with the second largest extinction event in history... The extinction is very little known becouse there are no dinosaurs involved... haha. But the cause of the extinction has not yet ben officialy determined. There are ofcourse theories, but none are really used as a label yet.
1) Oceans have living organisms, and2) Oceans cover about 2/3 of the surface of planet Earth.

No, child, I was not a witness to the Permian Extinction. The Permian extinction event is the only known mass extinction of insects. The Permian extinction event occurred about 252 million years ago.

Extinction.
The smallest complete living unit known to science is a single cell. The smallest single celled organisms known, mycoplasma, are not much bigger than the very largest viruses. Viruses are not technically considered to be living organisms by most scientists.
The collections of interbreeding organisms are called species. Species are capable of reproducing on their own and is often known as largest organisms.
The Permian-Triassic extinction event. Also known as the P-Tr extinction or the Great Dying, where 96% of all life died out.
