From Wikipedia, the free encyclopedia
Marine Isotope Stage 9 (MIS 9) was an interglacial period that consisted of two interstadial and one stadial period.[1][2] It is the final period of the Lower Paleolithic and lasted from 337,000 to 300,000 years ago according to Lisiecki and Raymo's LR04 Benthic Stack.[3] It corresponds to the Purfleet Interglacial in Britain,[4] the Holstein Interglacial in continental Europe,[5] and the Pre-Illinoian in North America.
