The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
The Late Pleistocene saw the extinction of many mammals weighing more than 40 kilograms (88 lb), including around 80% of mammals over 1 tonne. The proportion of megafauna extinctions is progressively larger the further the human migratory distance from Africa, with the highest extinction rates in Australia, and North and South America. [11]
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
Glaciation has been a rare event in Earth's history, [44] but there is evidence of widespread glaciation during the late Paleozoic Era (300 to 200 Ma) and the late Precambrian (i.e., the Neoproterozoic Era, 800 to 600 Ma). [45] Before the current ice age, which began 2 to 3 Ma, Earth's climate was typically mild and uniform for long periods of ...

There was a major extinction of large mammals globally during the Late Pleistocene Epoch. [19] Many forms such as sabre-toothed cats, mammoths, mastodons, glyptodonts, etc., became extinct worldwide. Others, including horses, camels and American cheetahs became extinct in North America. [20] [21]
An age is the smallest hierarchical geochronologic unit. ... Pleistocene: Upper/Late ('Tarantian') Eemian interglacial, last glacial period, ending with Younger Dryas.
The Middle Paleolithic was in the geological Chibanian (Middle Pleistocene) and Late Pleistocene ages. According to the theory of the recent African origin of modern humans , anatomically modern humans began migrating out of Africa during the Middle Stone Age/Middle Paleolithic around 125,000 years ago and began to replace earlier pre-existent ...
