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 Permian was the last period of the Paleozoic Era, spanning 299-351 million years ago. It was a time during which reptiles diversified. It ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history.
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
Permian refers to a geologic period that occurred between 299 million and 252 million years ago. It is known for being the last period of the Paleozoic Era and marked the dominance of reptiles, the origin of mammals, and the diversification of plants. The Permian period ended with the largest mass extinction in Earth's history, wiping out a significant portion of marine and terrestrial life.
The Devonian Period is a part of the Paleozoic Era, which covers the time from 541 to 252.17 million years ago. It began with the Cambrian explosion, in which most phyla of life began, and ended with the mass extinction called the Permian-Triassic extinction event.
The great extinction, also known as the Permian–Triassic extinction event, occurred around 252 million years ago. It was the most severe mass extinction event in Earth's history, resulting in the loss of over 90% of marine species and around 70% of terrestrial vertebrate species.

The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
It occurred between the Cretaceous period at the end of the Mesozoic era and the Tertiary period at the beginning of the Cenozoic era. It's mostly known for wiping out the dinosaurs. Any species that weighed over 100 kg vanished (60-80% of all species).
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.
A brief period of time in which large numbers of species die out and disappear is known as a mass extinction event. These events have occurred five times in Earth's history, with the most well-known being the extinction of the dinosaurs at the end of the Cretaceous period.
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.
The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
Mesozoic era
The Cretaceous–Tertiary extinction event 65 million years ago was the last mass-extinction, and many believe that humans are causing a mass-extinction right now.
The end of the Paleozoic era was marked by the Permian extinction event, also known as the Great Dying, which occurred around 252 million years ago. It was the most severe extinction event in Earth's history, leading to the extinction of about 90% of marine species and 70% of terrestrial vertebrate species.

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.
