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.
The Permian-Triassic Extinction is considered the largest extinction event in the history of life on planet Earth. This extinction event, which occurred approximately 252 million years ago, led to the extinction of up to 96% of all marine life and 70% of all other life, including insects.
Asteroids have been known to have caused mass extinctions. The obvious one is the Cretaceous--Tertiary extinction eventwhich wiped out the dinosaurs. Others, have also been noted.
Dinosaurs are the most famous of extinction but many species have died out from changing climate conditions, and we will probably never know have of them.
The last mass extinction occurred at the end of the Mesozoic Era-Cretaceous Period. 65 million years ago.
yes it can but it can
the holocene extinction
Mass extinction - More than 50% of the population went extinct in a short period of time.Background extinction - An average rate of extinction occurred during a given time period.

An asteroid impact caused a mass extinction about 65 million years ago
Notable extinctions during the last mass extinction included all non-avian dinosaurs, pterosaurs, plesiosaurs, and ammonites.
The effect of mass extinction is extinction, death of a mass
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.
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.
540 million years ago was the first mass extinction
asteroid attack
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.
