Period or supereon Extinction Date Probable causes Quaternary Holocene extinction c. 10,000 BC – Ongoing Humans Late Pleistocene extinctions 50,000 to 13,000 years ago Human overhunting and climate change Neogene Pliocene–Pleistocene boundary extinction2 MaPossible causes include a supernova or the Eltanin impact Middle Miocene disruption 14.5 Ma Climate change due to change of ocean circulation patterns. Milankovitch cycles may have also contributed Paleogene Eocene–Oligocene extinction event33.9 MaMultiple causes including global cooling, polar glaciation, falling sea levels, and the Popigai impactorCretaceousCretaceous–Paleogene extinction event66 MaChicxulub impactor; the volcanism which resulted in the formation of the Deccan Traps may have contributed.Cenomanian-Turonian boundary event94 MaMost likely underwater volcanism associated with the Caribbean large igneous province, which would have caused global warming and acidic oceans Aptian extinction117 MaUnknown, but may be due to volcanism of the Rajmahal Traps Jurassic End-Jurassic (Tithonian)145 MaNo longer regarded as a major extinction but rather a series of lesser events due to bolide impacts, eruptions of flood basalts, climate change and disruptions to oceanic systems Pliensbachian-Toarcian extinction (Toarcian turnover) 186-178 MaFormation of the Karoo-Ferrar Igneous Provinces TriassicTriassic–Jurassic extinction event201 MaVolcanism from the Central Atlantic magmatic province Carnian Pluvial Episode 234-232 Ma Wrangellia flood basalts, or the uplift of the Cimmerian orogenyOlenekian-Anisian boundary event247 MaOcean acidificationSmithian-Spathian boundary event249 MaLate eruptions of the Siberian TrapsGriesbachian-Dienerian boundary-event252Late eruptions of the Siberian TrapsPermianPermian–Triassic extinction event252 MaLarge igneous province (LIP) eruptions from the Siberian Traps, an impact event (the Wilkes Land Crater), an anoxic event, an ice age,Ice age, not warming, explains Permian-Triassic extinction event - UPI.com or other possible causesEnd-Capitanian extinction event260 MaVolcanism from the Emeishan Traps, resulting in global cooling and other effectsOlson's Extinction270 MaUnknown. Possibly a change in climate, but evidence for this is weak. This event may actually be a slow decline over 20 Ma.Carboniferous Carboniferous rainforest collapse305 MaPossibilities include a series of rapid changes in climate, or volcanism of the Skagerrak-Centered Large Igneous ProvinceSerpukhovian extinction~ 325 MaOnset of the Late Paleozoic icehouseDevonianHangenberg event359 MaAnoxia, possibly related to the Famennian glaciation or volcanic activityLate Devonian extinction (Kellwasser event)372 MaViluy Traps, Woodleigh Impactor?Taghanic Event~384 MaAnoxiaKačák Event~388 MaAnoxiaSilurian Lau event420 MaChanges in sea level and chemistry? Mulde event424 MaGlobal drop in sea level? Ireviken event428 MaDeep-ocean anoxia; Milankovitch cycles?OrdovicianLate Ordovician mass extinction445-444 MaGlobal cooling and sea level drop, and/or global warming related to volcanism and anoxia Cambrian Cambrian–Ordovician extinction event 488 MaKalkarindji Large Igneous Province? Dresbachian extinction event 502 Ma Sinsk event (End-Botomian extinction event) 513 Ma Precambrian End-Ediacaran extinction 542 MaAnoxic event Great Oxygenation Event 2400 MaRising oxygen levels in the atmosphere due to the development of photosynthesis as well as possible Snowball Earth event.
