Wolstonian glaciation
The Wolstonian glaciation is a name for an ice age period which occurred between 200,000 and 125,000 years ago. The name is used by British geologists and archaeologists who named it after the site of Wolston in the English county of Warwickshire where deposits of this stage weree first identified..
It is a Pleistocene stage of the Quaternary period and is analogous to the Illinoian glaciation in North America, the Warthe and Saalian glaciations in northern Europe and the Riss glaciation in the Alps. It was the penultimate glacial phase of the Pleistocene and its deposits have been found overlying material from the preceding Hoxnian interglacial and lying beneath those from the following Ipswichian interglacial.
Acheulian flint tools have been found in Wolstonian deposits.
