definition | The Pleistocene, often colloquially referred to as the Ice Age) is the geological
epoch which lasted from about 2,580,000 to 11,700 years ago, spanning the world's
most recent period of repeated glaciations. The end of the Pleistocene corresponds
with the end of the last glacial period and also with the end of the Paleolithic age
used in archaeology. The Pleistocene is the first epoch of the Quaternary Period or sixth epoch of the Cenozoic Era. In the ICS timescale, the Pleistocene is divided into four stages or ages, the Gelasian, Calabrian, Middle Pleistocene (unofficially the 'Chibanian') and Upper Pleistocene (unofficially the 'Tarantian'). In addition to this international subdivision, various regional subdivisions are often used. |
