Allerød Late glacial (i.e. late Devensian) period marking a prolonged warmer oscillation or interstadial during the general phase of ice retreat in NW Europe. Radiocarbon dating suggests it lasted from about 12 000 BP to 10 800 BP. Pollen records for the NW European area indicate a cool temperate flora with birch (Betula species) widespread, in marked contrast to the preceding and following, colder, Dryas, phases.
