During the 4th Extinction, or Triassic-Jurassic extinction, 90% of all species died within just 10,000 years. The 4th Extinction was thought by many scientists to have been caused by massive volcanic activity or asteroid impacts resulting in severe climate change.
Up to this year I'd say the dinosaurs still.
no, it happened about 250 million years ago. it was called The Great Dying.
--Also known as the Permian Extinction.
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.
A major extinction event.
i dont know y u askin me ;D
The Permian-Triassic extinction event. Also known as the P-Tr extinction or the Great Dying, where 96% of all life died out.
i heard that it was the exsistance and extinction of the dinosours and the continuing breakup of Pangaea
There were major asteroid impacts. #fuckschool #imheretohelp
Avian dinosaurs survived the extinction event of the dinosaurs.
the idea that extinction evedince is a natural event
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.
I think it's extinction. ------------------------------- More specifically an "extinction event".
An eruption of the Yellowstone caldera occurs it will likely be an extinction level event.
The Permian-Triassic Extinction Event happened at the end of the Paleozoic Era. It is widely recognised as the greatest extinction in Earths history. It was also known as the "Great Dying". 90% of all marine species, 60% of all land vertebrates and 58% of all genera of insects became extinct. It is the only known mass extinction of insects.
