Perm
Biologists estimate extinction rates in a great number of ways. One way is to document the decrease in population over time.
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
Several periods of mass extinction
Is extinction the word you're looking for ?
the answer to the question is extinction
Extinction of a single species can occur at any time if said species in hunted excessively, but mass extinction only occurs every 27 to 33 million years.

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.
No evidence of the extinct lifeforms appears in the stratigraphic record immediately following the extinction event.
Several periods of mass extinction
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
The Neanderthal's extinction happened many years ago. The extinction of the DoDo Bird made a great impact on the environment.
65 million years ago
Extinction is likely.
extinction
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
Some or several species become extinct every day.
