The locality Mikhailovka-5 is situated in the northern part of the Mikhailovka quarry in the northwest of the Kursk Oblast in central Russia. A rich mollusk fauna was collected along with small mammal remains from this lacustrine deposit located between Likhvinian (= Holsteinian) fossil soils and Valdayian (= Weichselian) periglacial deposits. The small mammal fauna is diverse, and includes numerous rodents, e.g., such indicative taxa as Arvicola ex gr. sapidus and Microtus ex gr. agrestis, a significant number of Clethrionomys glareolus and various insectivores. This assemblage closely corresponds to other Mikulino (= Eemian) faunas from the Russian Plain. The mollusk fauna includes a large number of terrestrial species, some of which have currently a more southern and western distribution. Both the molluskan and mammal faunas from Mikhailovka-5 indicate temperate climatic conditions, as evidenced by the diversity of insectivores, particularly the moles. Abundant remains of rodents of the genera Clethrionomys, Apodemus, and Microtus (Terricola) and of mollusks such as Acme, Macrogastra, Ruthenica, Punctum, and Acanthinula indicate the presence of extensive woodlands of mixed or broadleaf type, which were typical for this latitude during the Eemian interglacial. The palaeontological data provided in this paper, confirm that Mikhailovka-5 belongs to the Mikulino interglacial, as previously suggested by pedological arguments.

Eemian Interglacial

Small mammal remains obtained from the European localities dated to the Eemian (Mikulino) age have been analyzed for the first time at a regional scale based on the present biogeographical regionalization of Europe. The regional faunas dated to the warm interval in the first part of the Late Pleistocene display notable differences in fauna composition, species richness, and diversity indices. The classification of regional faunal assemblages revealed distinctive features of small mammal faunas in Eastern and Western Europe during the Eemian (=Mikulino, =Ipswichian) Interglacial. Faunas of the Iberian Peninsula, Apennine Peninsula, and Sardinia Island appear to deviate from the other regions. In the Eemian Interglacial, the maximum species richness of small mammals (≥40 species) with a relatively high proportion of typical forest species was recorded in Western and Central Europe and in the western part of Eastern Europe. The lowest species richness (5–14 species) was typical of island faunas and of those in the north of Eastern Europe. The data obtained make it possible to reconstruct the distribution of forest biotopes and open habitats (forest-steppe and steppe) in various regions of Europe. Noteworthy is a limited area of forests in the south and in the northeastern part of Europe. In these regions, it seems likely that under conditions of relatively high temperatures characteristic of the Last Interglacial and an insufficient moisture supply there could exist open forest stands or forest-steppe landscapes, as suggested by the presence of species indicative of forest-steppe and steppe north of the forest zone. The results obtained are useful in modeling changes in the mammal faunas as well as environmental changes in entire Europe due to global climatic changes (including the global warming recorded at present).

Evolutionary changes in European small mammals during the second half of the Middle Pleistocene, from the Likhvin (Holsteinian, Hoxnian) Interglacial (MIS 11) to the beginning of the Mikulino (Eemian) Interglacial (MIS 5e), that is between 424 ka BP and 130 ka BP were traced. Trends in evolutionary change were documented, and East European and West European faunas were compared. An integrated analysis of available theriological, geological, and geochronological data for the second half of the Middle Pleistocene in Europe has shown marked changes in the small mammal fauna throughout the period under consideration and provided information on the climate and environments at different time intervals. Changes traceable in the Arvicolinae phyletic lines made a correlation between the West European and East European mammal localities possible. The biostratigraphic scheme of the second half of the Middle Pleistocene has been developed and maps of small mammal localities compiled.

The paper is concerned with the small mammal fauna evolution in Europe in the Middle Pleistocene. The information on the faunas of the end of the Early Pleistocene has been also taken into consideration. The data available made possible identifying several stages in the small mammal evolution. Not all intervals within the Middle Pleistocene are provided with sufficient information for recognizing individual stages; that is particularly true for the cold periods of the Middle Pleistocene – the Donian and the Okian glaciations (=Elsterian, =Anglian). Based on the studies of small mammal localities, the biostratigraphic scheme has been developed, the principal phylogenetic lineages of Arvicolinae were traced, and maps of the Middle Pleistocene small mammal localities have been compiled

AbstractWe investigated fossil small mammals from a borehole near Moriaanshoofd (Zeeland, southwest Netherlands) in order to get better insights in the fossil mammal faunas that are found in the subsurface in the southwestern Netherlands, and to investigate the age and provenance of the mammal fauna that is being dredged from the deep tidal gullies in the nearby Oosterschelde estuary. The record in the borehole covers Gelasian (Early Pleistocene) to Holocene deposits, represented by six formations. Thirty-nine specimens of small mammals were obtained from the borehole. These fossils derived from the Early Pleistocene marine Maassluis Formation and from directly overlying deposits of a Late Pleistocene age. During Weichselian times (33–24 ka), a proto-Schelde River shaped the northern Oosterschelde area. The river reworked substantial amounts of Early and Middle Pleistocene deposits. At the base of the Schelde-derived fluvial sequence (regionally described as the Koewacht Formation), Gelasian vertebrate faunas were concentrated in the channel lag. The Late Pleistocene channel lag is almost certainly the main source for the rich Early Pleistocene vertebrate faunas with larger mammals dredged from the Oosterschelde.
