Absolutely not. We don't know all of the facts. The best guess is the Siberian Traps Theory. Its generally accepted, but by no means well-understood

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.
The Paleozoic Era is noted for what two changes?
The explosion of life in the Cambrian and the mass extinction of the Permian.
The deadliest of all mass extinctions which killed 95 percent of all living organisms was the?
Permian-Triassic extinction, 251 MYA (million years ago) in the Paleozoic 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 is one gradual change that can cause a mass extinction?
The Hallicigenia Apeared in the Cambrian Peirod.
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.
When did organisms suffer the largest mass extinction known?
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
Why was the permian extinction called the great dying?
The Permian extinction is called the "Great Dying" because it was earth's largest mass extinction which wiped out as much as 95% of life.
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 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 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.
What is Permian?
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 Paleozoic Era is noted for what two changes?
The explosion of life in the Cambrian and the mass extinction of the Permian.
How large was the Permian mass extinction?
95 percent of Earth's life was killed by hydrogen sulphide.
What are the areas on the geologic time scale?
Paleozoic Era- Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian Mass Extinction (Permian-Tertiary) 248 mya Mesozoic Era- Triassic, Jurassic, Cretaceous Mass Extinction (K-T) 65 mya Cenozoic- Tertiary, Quaternary
How many years ago was the largest mass extinction?
The most extreme that we are aware of was the Permian Extinction about 252 million years ago, in which 95% of all life was killed. The cause is still unknown, although it is possible that this was an impact event.
What event occurred about 250 million years ago and caused about 90 of the species living in the ocean to become extinct?
The Permian-Triassic mass extinction, aka "the Great Dying", the single most devastating mass extinction known.
