• NEANDERTHAL

Radiocarbon dates for both Lower and Upper Khavalynian transgressions fall in the timespan between 10 and 17 ka BP, with 13.6-11.8 ka BP, as the most probable age. This transgression supposedly proceeded as a rapid succession of sea-level fluctuations. The initial emergence of Mousterian industries in the Caspian basin as indicated by the Volgograd site, might be correlated with a mild interval preceding the Atelian regression, which was broadly contemporaneous with the last Glacial maximum (25-18 ka BP). The subsequent expansion of Mousterian sites was largely coeval with the Khvalynian transgression. Supposedly, specific environments that arose in the Caspian basin favoured a prolonged conservation of the Mousterian technique, and, possibly, a survival of Neanderthal populations. A possible factor is a 'cascade' of Eurasian basins that included the Caspian-Black Sea 'spillway', which effectively isolated the Caucasian-Central-Asian area.
