This is a list of extinction events, both mass and minor: [1] ... Extinction Date Probable causes [2] Quaternary: Holocene extinction: c. 10,000 BC – Ongoing ...
An extraterrestrial impact, which has occasionally been proposed as a cause of the Younger Dryas, [223] has been suggested by some authors as a potential cause of the extinction of North America's megafauna due to the temporal proximity between a proposed date for such an impact and the following megafaunal extinctions.
The following list is incomplete by necessity, since the majority of extinctions are thought to be undocumented, and for many others there isn't a definitive, widely accepted last, or most recent record. According to the species-area theory, the present rate of extinction may be up to 140,000 species per year. [1]
Most recent remains dated to 10250-9180 BCE (uncalibrated date). [55] Woodward's eagle: Buteogallus woodwardi: California to Florida and the Caribbean: Most recent remains dated to 38050-8050 BCE (uncalibrated date). [55] Neophrontops americanus: Rancho La Brea, California Most recent remains dated to 10230-7630 BCE (uncalibrated date). [55]
The largest extinction was the Kellwasser Event (Frasnian-Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods, and trilobites.
The indigenous fauna of the West Indies collapsed in the Late Quaternary, with the rate of extinction for terrestrial mammals approaching 79-84%, one of the highest in the world. However, in stark contrast to the American continent, radiocarbon dating indicates that mammals survived the end of the Pleistocene with no apparent, or minimal losses ...
Highly specialised for grazing, with the narrowest range of all Pleistocene ground quirrels. The latest possible date is the Atlantic, and its extinction was probably related to the local collapse of mammoth steppe.

The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
