- Pre-Pastonian Stage
The Pre-Pastonian Stage or Baventian Stage, is the name for an early
Pleistocene stage used in theBritish Isles . It precedes thePastonian Stage and follows theBramertonian Stage . This stage ended 1.806 Ma (million years ago) at the end of Marine Isotope Stage 65. It is not currently known when this stage started. The Pre-Pastonian Stage is equivalent to the Tiglian C4c Stage of Europe and the Pre-Illinoian J glaciation of the earlyPre-Illinoian Stage of North America.McMillan, A.A., 2005, "A provisional Quaternary and Neogene lithostratigraphic framework Great Britain", Netherland Journal of Geosciences. vol. 84, no. 2, pp, 87-107.] Gibbard, P.L., S.
