In general, it means a historical catastrophe so great that it caused multiple extinctions at the same time (or in a very short period of time) affecting multiple species of animals and plants, often across several ecosystems.
One well-known example is the meteor impact of 65.5 million years ago, which wiped out almost all the dinosaurs and other large creatures, all over the Earth. But that wasn't even the biggest extinction event: that would be the Great Dying of 251 million years ago, when 95% of marine species, and 70% of land species, disappeared in a geological blink of an eye.

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.
What is a very sudden elimination of a species from a catastrophic event?

What is the extinction level event of Yellowstone caldera?

What are the extinction of animals in the very distant past?
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
What is the dying out of many types of animals at once called?
A mass extinction or extinction event. For instance the death of the dinosaurs is the Cretaceous-Tertiary event (or K-T event for short).
Which event is the most likely to cause for the four periods when punctuated equilibrium seems to have occurred?
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "
When organisms disappear from earth?
An extinction event.
What happen at the of the era?
The Permian extinction event.
When did the Cretaceous Tertiary extinction occur?
About 65.5 million years ago. The Cretaceous and Tertiary are geological time periods either side of this event. The event is significant because there was a large mass extinction event at this time including the extinction of all non avian dinosaurs. Most experts agree that the cause of the extinction was a asteroid impact.
The largest extinction the world has ever known occurred at the end of which period?
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.
