The Wolstonian Stage is a middle

Eemian Stage in Europe and follows the Hoxnian Stage
in the British Isles.

It is also approximately analogous to the

Saalian stages in northern Europe; the Riss glaciation in the Alps; and the Illinoian Stage
in North America.

It is equivalent to Marine isotope stages (MIS) 10 through 6. MIS 10, 8 and 6 were glacial periods and 9 and 7 were interglacials.

It is named after Wolston in the English county of Warwickshire.

Description

The Wolstonian Stage is a middle

Saalian Stage in northern Europe and the Riss glaciation in the Alps, and temporally equivalent to all of the Illinoian Stage and the youngest part of the Pre-Illinoian Stage in North America. It is contemporaneous with the North American Pre-Illinoian A, Early Illinoian, and Late Illinoian glaciations.[1][2][3]

The Wolstonian Stage is equivalent to Marine isotope stages 6 through 10.[2][3]

Britain became an Island during this period (350,000 years ago).[4]

It started 374,000 years ago and ended 130,000 years ago.[5][6]

Etymology

The Wolstonian Stage was named after the site of Wolston in the English county of Warwickshire where corresponding deposits were first identified.[7]
