[QUOTE]Originally posted by rasol: [QB] [QUOTE]We find the same patterns, and therefore maps, cycle over and again thru African history, for example: [i]Approx. 125,000 - 120,000 y.a. Rainforest occupied a far greater area than at present, and rainfall was generally higher over north Africa. Data are sparse, mainly coming from long cores recording pollen and dust flux off the west coast of Africa. From these indicators, it seems that the situation generally resembled that of the early Holocene, around 8,000 14C y.a. General Eemian 'optimum' conditions in north Africa are summarized in map form by Frenzel et al. (1992) and by van Andel & Tzedakis (1996). Africa (map in preparation). 65,000 y.a. This map is taken from van Andel & Tzedakis (1996), and based on cores off the west coast of Africa. Sea level was about 75m below present level, but the extended coastlines are not shown here. Vegetation conditions seem to have been much as they were at the Last Glacial Maximum (see below), with greater-than-present desert extent in North Africa.
