Periode '''Kuarter''' merupakan [[Periode (geologi)|periode]] terakhir dari ketiga periode di [[Era (geologi)|era]] [[Kenozoikum]] dalam [[skala waktu geologi]].<ref name="ICS2009">[http://www.quaternary.stratigraphy.org.uk/correlation/GSAchron09.jpg See the 2009 version of the ICS geologic time scale]</ref> Periode ini berlangsung setelah periode [[Neogen]] dan membentang dari 2,588 ± 0.005 juta tahun yang lalu sampai sekarang. Waktu yang relatif singkat ini ditandai oleh serangkaian glasiasi dan dengan penampilan dan perluasan manusia modern secara anatomis.

Kuarter mencakup dua kala geologi: [[Pleistosen]] dan [[Holosen]].
==Iklim==
[[Iklim]]nya merupakan salah satu glasiasi periodik dengan gletser benua yang bergerak sejauh 40 derajat lintang dari kutub. Terjadi kepunahan besar mamalia besar di daerah Utara pada akhir Zaman [[Pleistosen]]. Banyak bentuk seperti [[kucing bergigi tajam]], [[mamut]], [[mastodon]], [[glyptodont]], dll., punah di seluruh dunia. Yang lainnya, termasuk [[kuda]], [[unta]], dan [[cheetah]] Amerika punah di Amerika Utara.<ref>{{Cite web|url =http://www.unr.edu/cla/anthro/people/faculty/haynes/download%20Haynes+StanfordCamelops.pdf|title =Stanford Camelops|last =Haynes|url-status =dead|archive-url =https://web.archive.org/web/20140309104319/http://www.unr.edu/cla/anthro/people/faculty/haynes/download%20Haynes+StanfordCamelops.pdf|archive-date =9 March 2014}}</ref><ref>{{Cite web|title = Extinct American Cheetah Fact Sheet|url = http://library.sandiegozoo.org/factsheets/_extinct/cheetah1_american/cheetah1_american.html|website = library.sandiegozoo.org|access-date = 10 December 2015|archive-url = https://web.archive.org/web/20160304023142/http://library.sandiegozoo.org/factsheets/_extinct/cheetah1_american/cheetah1_american.html|archive-date = 4 March 2016|url-status = dead}}</ref>
