The correlations between North and South are incorrect. The Menapian predates the Bavelian, and has, therefore, an age higher than 1 Ma. The exact age of the Menapian is unknown, as are the ages for the Eburonian and the Brüggen Kaltzeit. Ages that can be found in literature are rather speculative! As a matter of fact most correlations given here, except for Würm-Weichselian and Riss-Saalian are speculative.--Tom Meijer 21:01, 5. Aug. 2007 (CEST)
