Definition of Cromerian in English:



  • 1Relating to or denoting an interglacial period in the Middle Pleistocene of Britain and northern Europe, preceding the Elster (Anglian) glaciation.

    • ‘Preceding and separating the cold glacial periods were three main interglacials (Cromerian, Hoxnian, and Ipswichian) when the climate was rather warmer.’
    • ‘We were looking at deposits of lower and middle Pleistocene age here; the Lowestoft Till of the Anglian glaciation resting as fallen blocks on the dark, organic layer of the Cromerian interglacial fresh water bed.’
    • ‘The site in which it was collected is the type site for the Cromerian interglacial period and is a prehistoric river bed that existed over 500,000 years ago in north Norfolk, England.’
    • ‘In 1969 blasting at a Somerset quarry exposed a massive cave, filled with well-preserved faunal remains and flint artefacts attributed to the Cromerian interglacial of the Middle Pleistocene.’
    • ‘The length of this Middle Pleistocene stage is still unclear, but the sediments indicate that the Cromerian period was characterised by flucutuations between cold and temperate climates.’
    1. 1.1The Cromerian interglacial period or the system of fossil-rich deposits laid down during it.
