The largest extinction the world has ever known occurred at the end of which period?
Travok
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.

What is the period after Devonian Period known as?
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
When did organisms suffer the largest mass extinction known?
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
How do I use Permian Extinction in a sentence?
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 brief period of time in which large numbers of species die out and disappear?
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.
How did Ordovician period ended?
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.
What era did organisms suffer largest mass extinction known?
Mesozoic era
When was the last mass extinction?
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.
What era had 95 percent of species die out?
The worst known mass extinction in Earth's history was the Permian-Triassic Extinction Event at the end of the Permian period. The Permian period was the last period of the Paleozoic Era.
What is the k-t mass extinction and when did it occur?
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).
What event marks the end of both the Paleozoic Era and Mesozoic Era?
The Permian-Triassic (P-Tr) Extinction Event is widely recognised as the greatest extinction event on Earth. It is also known as the "Great Dieing".It occurred 251 million years ago marking the end of the Permian Period and the start of the Triassic Period.It also marks the end of the Paleozoic Era and the start of the Mesozoic Era. Estimates have suggested that 96% of marine species and 70% percent of land vertebrate species became extinct. It is also the only known mass extinction of insect with 56% of insect families and 83% of insect genera becoming extinct.Little is known of the cause of the mass extinction but theories range from meteorite impacts, to volcanism, to sea level fluctuations.
