text: The Middle Pleistocene is a subdivision of the Pleistocene Epoch, from 781,000
to 126,000 years ago (781–126 ka). It is preceded by the Calabrian stage, beginning
with the Brunhes–Matuyama reversal, and succeeded by the Tarantian stage (equivalent
to the Late or Upper Pleistocene), taken as beginning with the last interglacial (MIS
5).
The tripartite subdivision of the Pleistocene into Lower (Early), Middle and Upper
(Late) has been in use since the 1930s. It is in use as a provisional or "quasi-formal"
designation by the International Union of Geological Sciences (IUGS) as of 2018,
pending the ratification of the 2017 proposal by the International Commission on Stratigraphy
(Subcommission on Quaternary Stratigraphy, ICSSQS) of the Chibanian stage.
