Late Pleistocene extinctions was nominated as a Natural sciences good article, but it did not meet the good article criteria at the time (August 12, 2022). There are suggestions on the review page for improving the article. If you can improve it, please do; it may then be renominated. |

This article was nominated for merging with Holocene extinction on 24-08-21. The result of the discussion was Not merged. |
On 15 December 2023, it was proposed that this article be moved from Late Pleistocene extinctions to Late Pleistocene extinctions. The result of the discussion was moved. |
This is a surprisingly terrible article that goes out of its way to argue for the Overkill hypothesis, when that hypothesis has its own article. It's crap and definitely needs expert attention. —Preceding unsigned comment added by 24.235.139.169 (talk) 08:01, 27 August 2009 (UTC)
This is not an extinction event. I propose that this thread be renamed to "Quaternary extinction" to be more scientific. —Preceding unsigned comment added by 66.75.37.247 (talk) 02:09, 29 October 2009 (UTC)
Yes, but several of the events occurred within a few generations due to the combined effects of the root stimuli and nuclear winter. When the affects of nuclear winter are added, the timeframe is reduced considerably. —Preceding unsigned comment added by 66.75.37.247 (talk) 20:49, 31 October 2009 (UTC)
There seems to be a lot of edits recently making "arguments against" various hypotheses. Admittedly, I'm not up-to-date on the latest scientific literature, so hopefully someone's keeping an eye on this. We need to be sure that neither side (for or against the Overkill hypothesis) is given undue weight and the article meets WP:NPOV. I have noticed a few weasel words in the article, so it clearly needs review by an expert. –Visionholder (talk) 22:07, 12 January 2010 (UTC)
my first remark is that it is contained several times in the article that a seperation of the bison of 240Ka left it naive. wich is unsourced. also i think it is not true. since firstly evolutionairy adaptions dont necessarilly disappear without trace in such a short period (morphologically they tend to do not). and secondly it is unclear if this adaption would have a possible positive effect on the species survivability in the abscence of humans, it may eg. have helped against predation through shortfaced bear (roughly similar size and looks), or canines( that share a roughly similar hunting method with humans). so i would like to see it sourced and provided with examples. my other remark is that even very small numbers of eg. seal hunters (like 1 or a few crews so under 100 individuals) managed to extinguish complete colonies of sea-mammals in mere years and species in at most decades. since that was not uncommonly done by clubbing or spearing it also shows no advanced technology's are needed for it.24.132.171.225 (talk) 04:34, 8 March 2010 (UTC)
later in article i find this: "Such a disease needs to be capable of killing of three species of bison while leaving a third very closely related species unaffected." wich in my opinion renders the whole bison argument very moot. it shows we actually have to do with either an adapted species, the most adaptable species, or a species that was kept in a certain regard (not necessarily reference) by humans, a thing btw wich is strongly suggested by the dependency of plains cultures of the bison. fascinatingly i think evidence for this could be found. one thing that would eg. be telling is if the other bison species migrated over considerably smaller distances, that could be habitually covered by humans. other reasons for preferential predation by humans could be more meat per kill, a more agressive species (that would simply put provide a hunter with bigger praise, or even result in considerable effort to hunt the animal for safety reasons). there is a sheer endless list of such factors, eg. a strong family bond like in elephants that stay with the dead would be lethal for any animal intensively hunted, yet more usefull or less adapted to humans then elephants, etc.24.132.171.225 (talk) 04:48, 8 March 2010 (UTC)
The megafauna demise in Siberia appeared to have coincided with dramatic increase in rainfall at the Preboreal. The youngest fossils are about 9300 carbon years BP ~ 11,000 calendar years. The mammoth steppe changed into marshes and swamps, which was totally unsuitable for mammoths etc. Islands like Wrangel island tend to have their own micro climate, reason why the mammoths could have survived for a longer periodThere is no evidence of human occupation at the majority of the last refugia (ic Taimyr peninsula ). Obviously this is in favor of the climate change hypothesis. I intend to add that shortly.
This major event of oceanic foraminifera extinction in the mid pleistocene is at least as dramatic as the mammal extinctions, however totally unknown to wikipedia. I wonder if this warrants a new seperate article or another chapter here. Thoughts? http://jfr.geoscienceworld.org/content/32/3/274.abstract

it appears a little earlier. on the mega faunal extinctions i am rather of the human caused kind, if even because humans also burned large areals of forests, and killed animals in unneccesary masses.i dont think that would immediatly impact deep sea organisms. yet on the megafauna there is this: allthough less specialised animals may change in a period of about 100ka, highly specialised herbivores or carnivores could not. animals that first met men, (famous examples, dodo , lemurs, australian animals but if you dig deeper there are plenty stories, even of animal that had at other places had contact with humans, ) tend to not have any fear, which is deadly for herbivores, and not the safest way to deal with a new species for a carnivore either. so whether through overkill, ecological impact, ritual or depletion, the macro fauna had a very bad time. african animals that had been exposed to humans , and co-evolved fare better, still it is a standing tradition, to kill a lion eg. for to "be a man". usually human population density is bigger than is carnivore (..)(btw since it is close to australia..)31.151.163.18 (talk) 00:27, 17 July 2017 (UTC)
Why is this article entitled "Quaternary extinction event"? Search on google scholar yields only 10 (sic!) results; of those, 5 actually uses the phrase "late Quaternary extinction event", and 1 other "end-Quaternary extinction event". But only 3 from those 10 clearly use this phrase to refer to the subject of this article (the wave of extinctions), while the rest refers to some specific "event" that was a part of the wave.

There are two articles on the same topic. Holocene extinction — Preceding unsigned comment added by 164.159.62.2 (talk) 19:50, 27 August 2013 (UTC)
I strongly disagree. These extinctions here, were mostly occurring near the Pleistocene–Holocene boundary. The Holocene extinction is ongoing with a stronger onset of the last 200 years. Aruck (talk) 13:54, 29 December 2022 (UTC)
