Cromerian interglacial

From Wikipedia, the free encyclopedia

The Cromerian interglacial is a name for an interglacial period which occurred between 600,000 and 450,000 years ago. The name is used by British geologists and archaeologists who named it after the site of West Runton near Cromer in the English county of Norfolk where deposits it created were first found.

It is a Pleistocene stage of the Quaternary period and is analogous to the Aftonian interglacial in North America and the Günz-Mindel interglacial in the Alps. It was a period of warm climate and its deposits lie beneath those from the following Anglian glaciation and above those from the preceding Beestonian glaciation.
