Beestonian stage
From Wikipedia, the free encyclopedia
The Beestonian stage is the name for an early Pleistocene glacial stage used in the British Isles. It preceded the Cromerian interglacial and is therefore in a similar sequential position to the Nebraskan glaciation in North America, the Günz glaciation in the Alps and the Eburonian glaciation in north Europe. It is named after Beeston Cliffs near West Runton in Norfolk where deposits from the period are preserved.
It appears to have been an alternating period of cold and warm phases rather than a continuous ice age and occurred around 600,000 years ago. It was preceded by the Pastonian interglacial.
