the holocene extinction
Catastrophic extinction event.
Mesozoic
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.
An asteroid impact
Notable extinctions during the last mass extinction included all non-avian dinosaurs, pterosaurs, plesiosaurs, and ammonites.
Many geologists consider what you call the "last ice age" to be the last glacial of the present Ice Age, with the ice retreat starting only about 10-12ka. There was no mass extinction. A good many species did migrate or disappear altogther as the ice retreated, but in no way was it a mass extinction.
The effect of mass extinction is extinction, death of a mass
65 million years ago
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.
the holocene extinction
The dinosaurs fell victim to a mass extinction.
This would be called a mass extinction or mass die off.This would be called a mass extinction.
asteroid attack
540 million years ago was the first mass extinction
We are still not sure what caused the mass extinction of the dinosaurs, though an asteroid impact seems to be the popular theory.Scientists believe we may be heading towards another mass extinction event.
