Аннотация: An analysis of voluminous data on the European fossil small mammals datable to theDnieper (= Saalian) Glaciation (MIS 6) allowed to establish the main characteristics ofthe species composition in the faunas, their distribution and diversity. As is shown bythe analysis, the faunas of small mammal underwent cardinal changes within thesubcontinent boundaries at that time, with the exception of the faunas of the southernpeninsulas. Some subarctic species are proved to penetrate southwards as far as 48°N in Western Europe and up to southern France and the British Isles in WesternEurope. The steppe species enlarged their ranges to the east and to the west (up tothe British Isles). This fact suggests the disappearance of the continuous forest zone.Occasional forest mammal species persisted in Eastern Europe; in most localities ofWestern Europe, however, forest mammal remains are present along with those ofsteppe and subarctic mammals. A structural stability of mammal faunas was preservedon the southern peninsulas that had not been heavily influenced by the glaciation. Noanalogue“mixed” mammal assemblages developed over the greater part of Europe.The transition to the Mikulino (= Eem) Interglacial was marked by changes in thestructure of mammal assemblages on the subcontinent. The ranges of subarcticmammal species shifted northwards, the forest zone was restored gradually, whichwas served to the restoration of forest species populations. Steppe species rangesshifted to the east of Europe. Unlike the no-analogue faunas of the Dnieper (= Saale)Glaciation, noted for “mixed” composition of mammals belonging to ecologicallydifferent groups, the Mikulian (= Eemian) faunas acquired the zonal structure. Thepaper was primarily aimed at estimating general regularities in the small mammalfauna distribution beginning from the level of individual species to regional faunalcomplexes. We concluded that the small mammal fauna of the late Saale (= Dnieper)ice age responded to the Mikulian (= Eemian) warming in a way not unlike the LatePleistocene “ Mammuthus–Coelodonta Faunal Complex” response to the Holocenewarming, though with a lesser loss of the species richness.
