A Late Pleistocene Extinction Period (50 KYA to 10 KYA) is an extinction period around the Late Pleistocene (associated with Late Pleistocene species extinction).
- AKA: Late Quaternary Extinction Event, End-Pleistocene Extinction.
- Context:
- It can typically affect Late Pleistocene Megafauna Populations with late pleistocene predator-prey relationships.
- It can typically eliminate Late Pleistocene Keystone Species through late pleistocene extinction mechanisms.
- It can typically occur across Late Pleistocene Continental Regions with late pleistocene habitat destruction and late pleistocene climate shifts.
- It can typically alter Late Pleistocene Ecosystem Structure through late pleistocene trophic cascades.
- It can typically leave Late Pleistocene Fossil Record with late pleistocene extinction signatures.
- It can typically demonstrate Late Pleistocene Human Hunting Intensity through late pleistocene archaeological kill sites and late pleistocene butchery mark patterns.
- It can typically correlate with Late Pleistocene Human Population Expansion across late pleistocene geographical barriers.
- It can typically show Late Pleistocene Prey Naivety Pattern where late pleistocene megafauna species lacked late pleistocene anti-human defense mechanisms.
- ...
- It can often involve Late Pleistocene Human Activity through late pleistocene hunting practices and late pleistocene landscape modifications.
- It can often correlate with Late Pleistocene Climate Change Episode through late pleistocene temperature fluctuations.
- It can often preserve Late Pleistocene Extinction Pattern in late pleistocene sedimentary layers.
- It can often be studied through Late Pleistocene Carbon Dating Methods and late pleistocene paleoecological reconstructions.
- It can often leave Late Pleistocene Archaeological Evidence including late pleistocene projectile points associated with late pleistocene megafauna remains.
- It can often exhibit Late Pleistocene Human-Climate Synergistic Effect where late pleistocene human pressure compounded late pleistocene environmental stress.
- ...
- It can range from being a Gradual Late Pleistocene Extinction Event to being a Rapid Late Pleistocene Extinction Event, depending on its late pleistocene extinction timeframe.
- It can range from being a Regional Late Pleistocene Extinction Event to being a Global Late Pleistocene Extinction Event, depending on its late pleistocene extinction geographical extent.
- It can range from being a Selective Late Pleistocene Extinction Event to being a Mass Late Pleistocene Extinction Event, depending on its late pleistocene extinction taxonomic breadth.
- It can range from being a Minimal Human Influence Late Pleistocene Extinction Event to being a Dominant Human Influence Late Pleistocene Extinction Event, depending on its late pleistocene human causation proportion.
- It can range from being a Direct Human Predation Late Pleistocene Extinction Event to being an Indirect Human Ecosystem Modification Late Pleistocene Extinction Event, depending on its late pleistocene human impact mechanism.
- It can range from being a Blitzkrieg-Pattern Late Pleistocene Extinction Event to being a Protracted Human Impact Late Pleistocene Extinction Event, depending on its late pleistocene human-megafauna interaction timespan.
- ...
- It can involve Late Pleistocene Megafaunal Taxons including late pleistocene proboscidean groups, late pleistocene large carnivore species, and late pleistocene large herbivore species.
- It can demonstrate Late Pleistocene Size-Biased Extinction Pattern with late pleistocene body mass threshold correlations.
- It can interact with Late Pleistocene Human Migration Routes and late pleistocene human technology developments.
- It can be explained by Late Pleistocene Extinction Hypothesis including late pleistocene overkill hypothesis and late pleistocene climate hypothesis.

- Examples:
- Late Pleistocene Continental Extinction Events, such as:
- North American Late Pleistocene Extinction Event (11,000-14,000 years ago), characterized by late pleistocene megafaunal collapse affecting over 70% of late pleistocene large mammal species.
- South American Late Pleistocene Extinction Event (12,000-15,000 years ago), coinciding with late pleistocene human arrival and late pleistocene environmental change.
- Australian Late Pleistocene Extinction Event (40,000-50,000 years ago), eliminating late pleistocene marsupial megafauna and late pleistocene flightless bird species.
- Eurasian Late Pleistocene Extinction Event (14,000-40,000 years ago), showing late pleistocene staggered extinction pattern across late pleistocene geographical gradients.
- African Late Pleistocene Extinction Event (11,000-30,000 years ago), demonstrating late pleistocene reduced extinction intensity compared to other late pleistocene continental regions.
- Late Pleistocene Taxon-Specific Extinction Events, such as:
- Late Pleistocene Mammoth Extinction Event (11,000-12,000 years ago), eliminating late pleistocene mammoth populations across most late pleistocene northern hemisphere habitats.
- Late Pleistocene Ground Sloth Extinction Event (10,000-11,000 years ago), resulting in complete late pleistocene ground sloth disappearance from late pleistocene American continents.
- Late Pleistocene Saber-Toothed Cat Extinction Event (11,000-12,000 years ago), coinciding with late pleistocene prey species loss and late pleistocene ecological restructuring.
- Late Pleistocene Island Extinction Events, such as:
- Late Pleistocene Madagascar Extinction Event (2,000-4,000 years ago), affecting late pleistocene malagasy megafauna following late pleistocene human colonization.
- Late Pleistocene New Zealand Extinction Event (700-800 years ago), eliminating late pleistocene moa species and other late pleistocene endemic fauna.
- Late Pleistocene Caribbean Island Extinction Event (4,000-5,000 years ago), characterized by late pleistocene ground sloth elimination and late pleistocene rodent species loss.
- Late Pleistocene Human Impact Evidence Sites, such as:
- Monte Verde Late Pleistocene Archaeological Site (14,500 years ago), demonstrating late pleistocene human butchery of extinct late pleistocene gomphotheres.
- Wally's Beach Late Pleistocene Archaeological Site (13,300 years ago), showing late pleistocene human hunting activity with late pleistocene horse and late pleistocene camel remains.
- Kostenki Late Pleistocene Archaeological Site (40,000-45,000 years ago), revealing late pleistocene human mammoth exploitation with late pleistocene structured bone deposits.
- Předmostí Late Pleistocene Archaeological Site (27,000-25,000 years ago), containing over 1,000 late pleistocene mammoth individuals with late pleistocene human-modified bones.
- Meadowcroft Rockshelter Late Pleistocene Archaeological Site (14,500-16,000 years ago), showing late pleistocene human presence preceding major late pleistocene extinction pulses.

- Late Pleistocene Continental Extinction Events, such as:
- Counter-Examples:
- Holocene Extinction Event, which occurs after the pleistocene-holocene boundary and involves predominantly anthropogenic extinction mechanisms rather than late pleistocene extinction mechanisms.
- End-Cretaceous Extinction Event, which occurred 66 million years ago rather than during the late pleistocene period and was caused by asteroid impact rather than late pleistocene extinction mechanisms.
- Late Pleistocene Species Migration, which involves late pleistocene geographical range shift rather than late pleistocene species elimination.
- Late Pleistocene Faunal Turnover, which represents late pleistocene community composition change without necessarily involving late pleistocene extinction.
- Late Pleistocene Human-Megafauna Coexistence Region, which demonstrates late pleistocene megafauna survival despite late pleistocene human presence due to late pleistocene robust ecosystem or late pleistocene behavioral adaptation.
- Late Pleistocene Anthropogenic Habitat Modification, which involves late pleistocene landscape change without immediate late pleistocene extinction but contributes to late pleistocene ecological pressure.
- Late Pleistocene Indigenous Conservation Practice, which represents late pleistocene human cultural adaptation that mitigated late pleistocene extinction pressure through late pleistocene sustainable hunting strategy.
- Late Pleistocene Megafauna Refuge Area, which provided late pleistocene geographical protection from late pleistocene human hunting pressure due to late pleistocene inaccessible terrain.
