Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
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.
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.
How do you use permian extinction in a sentence?
The Permian extinction caused about 95% of Earth's life to die.
Did the cretaceous or permian extinction cause dinosaurs to become extinct?
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
How many extinctions has earth experienced in its history?
Mass extinctions--at least two--one at the end of the Permian, and one at the end of the Cretaceous, with numerous other less severe events. As far as the extinction of individual species, that list would cover millions of extinct organisms.
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 effects have mass extinctions had on history life?
Mass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.
Did the Permian extinction come before the the dinosaur extinction?
Yes. At the time of ther Permian extinction 251 million years ago dinosaurs had not yet evolved. The dinosaur extinction was 65 million years ago.
What happen at the of the era?
The Permian extinction event.
What ended the permian period?
The Permian Period was ended by the Permian/Triassic Extinction Event, which wiped out 90% of the species on Earth at that time.
