In areas with limited glacial impact, the term "Epipaleolithic" is sometimes preferred for the period. Regions that experienced greater environmental effects as the Last Glacial Period ended had a much more apparent Mesolithic era that lasted millennia. In Northern Europe, societies were able to live well on rich food supplies from the marshlands, which had been created by the warmer climate. Such conditions produced distinctive human behaviours that are preserved in the material record, such as the Maglemosian and Azilian cultures. Such conditions delayed the coming of the Neolithic to as late as 5,500 years ago in Northern Europe.
