    Introduction

    The best represented vertebrate records in the early and middle

    Pleistocene of Northern Eurasia are mammalian and they are

    summarized in this article. The data from Russia and neigh-

    boring countries of the former USSR are very important for the

    understanding of the history of Late Cenozoic biota. The terri-

    tory was a prime area of origin and evolution of taxa and of

    dispersals of some mammals to Western Europe, Africa, North

    America and China, and vice versa. The configuration of Asia

    was close to that of the present day but differed through the

    periodic existence of the Bering land bridge, connecting Siberia

    and Alaska. The reorganization of the biota went through

    climatic and environmental changes; its main trends and

    phases are very pronounced there.

    The key stages in the history of Pleistocene mammals in this

    territory were first recorded by Gromov (1948) who defined

    the faunal assemblages for Eastern Europe and named them by

    their type localities or regions. Regional complexes were later

    defined in the Caucasus, Siberia, Transbaikalia, and Central

    Asia. The data on the ages of the assemblages and their com-

    positions were considerably enriched thanks to many subse-

    quent researchers and new discoveries. In addition to large

    mammals, a detailed biochronology based on small mammals

    has appeared in the last decades. At present, early and middle

    Pleistocene mammal remains are known from many localities

    of Northern Eurasia. The age of the localities has been estab-

    lished by a combination of geological and paleontological

    methods (including the first appearance of index taxa, as well

    as the evolutionary levels of dominant forms and of some

    phyletic lineages), paleoclimatic data and correlation. Paleo-

    magnetic data also help to distinguish more precisely the age of

    early Pleistocene sites, whereas the glacial–interglacial succes-

    sion provides further important markers for age determination.

    The beginning of the Pleistocene is currently set at �2.6 Ma(the Gauss–Matuyama magnetic reversal), the early–middle

    Pleistocene boundary at �0.78 Ma (the Brunhes–Matuyamamagnetic reversal), and the middle–late Pleistocene boundary

    at 0.126 Ma, according to the International Commission on

    Stratigraphy in 2009. However, the Geological Surveys of

    Russia and Ukraine have until recently retained the Pliocene–

    Pleistocene boundary in its former position at 1.8 Ma. In 2012

    the Russian Stratigraphic Committee voted to lower the base of

    the Quaternary to 2.58 Ma. The position of the lower boundary

    of the Pleistocene and its divisions have thus been repeatedly

    changed over the last decades and it must be appreciated that

    the published names of particular stratigraphical units often

    refer to different time slices.

    The early and middle Pleistocene in Northern Eurasia

    currently include the following mammal assemblages:

    Khaprovian, 2.6–2.2 Ma; Psekupsian, 2.2–1.2 Ma; Tamanian,

    1.2–0.8 Ma; Tiraspolian, 0.8–0.4 Ma; Singilian and Khasarian,

    0.4–0.126 Ma.

    Early Pleistocene: Gelasian, Middle Villafranchian, LateVillanyian, MN17

    The Khaprovian (Khapry) mammal assemblage and itsanalogsThis stage is well documented in the northern Black Sea region,

    peri-Azov area, Siberia, and Central Asia. The mammal com-

    munities superficially resembled those of modern Africa or

    southern Asia by the presence of proboscideans, equids, rhi-

    noceroses, giraffids, and various antelopes, but differed

    considerably from them in species composition. These assem-

    blages are characterized by the first appearance and subseq-

    uent wide distribution of the elephant Archidiskodon gromovi

    (¼ A. meridionalis gromovi in Titov, 2008, ¼ Mammuthus gro-movi of Lister and Sher, 2001). In contrast to Russian paleon-

    tologists, most researchers refer this species to the genus

    Mammuthus, mainly based on the tooth structure (Lister and

    Sher, 2001), although Archidiskodon is retained here. Other

    features of the fauna include the presence of the bear Ursus

    etruscus and the rhinoceros Stephanorhinus sp., the rapid

    diversification and wide distribution of stenonid horses,

    the presence of diverse canids (Eucyon, Nyctereutes, Canis), two

    saber-toothed cats Homotherium crenatidens and Megantereon

    cultridens, the camel Paracamelus, the large-sized comb-antlered

    deer Eucladoceros and the elk (¼ moose) Libralces, and otherextinct forms. In Northern Eurasia, there were three paleozoo-

    geographic subareas: European-Siberian, Mediterranean, and

    Central Asian (Vangengeim and Pevzner, 1991; Vislobokova

    et al., 1995) (Figure 1). The global cooling witnessed at about

    2.6 Ma (indicated in the territory by the glaciations of the

    Caucasus and Pamir, the most ancient loess formation in

    Tadjikistan, Uzbekistan, etc.) caused a decrease in humidity

    in temperate latitudes and in Central Asia (Dodonov, 2002),

    where animals adapted to open woodlands and grasslands

    became dominant. Some taxa have North American ancestry,

    immigrating during periods of low sea level prior to the start

    of the Pleistocene, such as the camels, Hipparion and Eucyon

    in the late Miocene, and Equus, Canis, and Megantereon in the

    Pliocene (Vislobokova et al., 2003). A number of thermophilous

    herbivores (mastodons, giraffids, and others), typical of Pliocene

    times, were gradually replaced by forms adapted to cooler cli-

    matic conditions and possessing more advanced herbivorous

    adaptations. The data on herbivorous taxa (elephants, horses,

    ruminant Artiodactyla, voles, etc.) are of great value for biochro-

    nology and paleoenvironmental reconstruction because their

    tooth structure yields clearly recognizable signals inwear patterns,

    hypsodonty, etc. The increase in diversity of herbivore taxa was

    accompanied by considerable changes in the carnivore guild.

    At this time, an extensive European-Siberian part of the

    Palearctic was inhabited by the elephant Archidiskodon gromovi,

    the rhinoceros Elasmotherium, and large Equus livenzovensis

    and small Equus sp., together with other animals adapted to

    savanna-like conditions (the wolves of the Canis etruscus group,

    the hyena Pliocrocuta, the saber-toothed cat Homotherium cre-

    natidens, the cheetah Acinonyx, the camel Paracamelus, the an-

    telope Gazellospira, the bison-like Leptobos, and others), along

    with forest and ecotonal animals (the bear Ursus etruscus and

    the deer Eucladoceros and Libralces). Most of these mammals

    were found in common with those from the Middle Villafran-

    chian faunas of Western Europe (Kahlke et al., 2011; Palombo

    et al., 2006). Early Villafranchian elements (the mastodon

    Anancus arvernensis, the archaic horse Hipparion, and giraffids)

    became very rare. Among the small mammals, the bank voles

    Clethrionomys made their first appearance, the water vole Mim-

    omys polonicus was replaced by M. pliocaenicus in the Northern

    Black Sea area, and the pikas Pliolagomys and Ochotona and

    jerboas Allactaga, more typical of Asian faunas, were present.

    Fossil remains of Archidiskodon gromovi, the main indicator

    species of the Khaprovian mammal assemblage, have been

    found in a number of localities in the European part of

    Russia (Khapry, Liventzovka, and others), in the Ukraine

    (Zhevakhova Gora), in the south of Western Siberia (Podpusk-

    Lebyazh’e), and inCentral Asia (Adyrgan, Kuruksay) (Bajgusheva,

    1971; Garutt and Bajgusheva, 1981; Vangengeim et al.,

    1988; Vislobokova, 1996, 2005; and others). A. gromovi

    has also been found in Italy (Montopoli) (Gliozzi et al.,

    1997).

    Remains of other members of the Khaprovian assemblage

    are recorded from many European–Russian sites along the

    northern coast of the Sea of Azov and the right bank of the

    Encyclopedia of Quaternary Scienc

    Don River near Rostov-on-Don and Taganrog. They come from

    the lower part of the Khapry alluvium recorded in sand pits

    and natural outcrops. The large mammals were represented by

    Anancus arvernensis alexeevae, the horses Hipparion moritorum,

    Equus (Allohippus) livenzovensis, and a small Equus sp., the rhi-

    noceroses Stephanorhinus ex gr. megarhinus-kirchbergensis and

    Elasmotherium chaprovicum (¼ E. cf. caucasicum), the wild boarSus strozzi, the camels Paracamelus alutensis and Paracamelus cf.

    gigas, the deer Cervus (Rusa) philisi, Eucladoceros cf. dicranios,

    Arvernoceros sp., and Libralces gallicus, the giraffid Palaeotragus

    (Yuorlovia) priasovicus, and the bovids Leptobos sp., Gazellospira

    gromovae, Tragelaphini gen. indet., Gazella cf. subgutturosa, and

    others (Alexeeva, 1977; Bajgusheva, 1971; Bajgusheva et al.,

    2001; Gromov, 1948; Titov, 2008; and others) (Figure 2). The

    Khapry carnivores included the raccoon-dog Nyctereutes mega-

    mastoides, Canis sp. (C. cf. senezensis : Sotnikova et al., 2002),

    the mustelids Lutra sp. and Pannonictis nesti, the medium-sized

    hyena Pliocrocuta perrieri and the dominant larger-sized

    short-faced hyena Pachycrocuta brevirostris, the felids Lynx issio-

    dorensis, the saber-toothed catHomotherium crenatidens, and the

    cheetah Acinonys pardinensis. Most of these animals were in-

    habitants of open savannah-like landscapes, with a part of the

    fauna adapted more to forested or ecotonal zones (mustelids,

    lynx, wild boar, and deer). Among the small mammals, the

    archaic lagurine Borsodia praehungarica, the water volesMimomys

    praepliocaenicus and Mimomys ex gr. reidi, and the primitive red-

    backed voles Clethrionomys kretzoii were also present (Tesakov,

    2004).

    Author's personal copy

    In the south of Western Siberia, faunal assemblages

    described by Vangengeim and Zazhigin have been reported

    from Podpusk-Lebyazh’e, from the lower part of the thick

    sandy alluvial deposits exposed on the right bank of

    the Irtysh River, south of Pavlodar (Vangengeim, 1977;

    Vislobokova, 1996; Figure 3). Typical members include A.

    gromovi, S. cf. etruscus, Elasmotherium sp., Equus livenzovensis,

    Equus sp. (small), Paracamelus cf. gigas, Eucladoceros sp., Lepto-

    bos, and the antelopes Gazella cf. sinensis and Antilospira

    cf. gracilis (Vislobokova, 1996). The faunal assemblage con-

    sisted mainly of forms widespread in the temperate zone of the

    Palearctic region (Ursus cf. etruscus, Homotherium, Pachycrocuta,

    and others), with some Central Asian elements (Ochotonoides,

    Elasmotherium, Paracamelus, Antilospira cf. gracilis, Gazella

    cf. sinensis), some of which (e.g., Paracamelus) reached Eastern

    Europe. Among the small mammals, voles with rooted denti-

    tion of the genus Mimomys (M. pliocaenicus and M. reidi) and

    Borsodia (B. praehungarica-petenyii) were predominant and

    Clethrionomys appeared for the first time in Siberia (Zazhigin,

    1980). The mammalian assemblages indicate the prevalence

    of steppes with woodland developed along river valleys.

    Encyclopedia of Quaternary Scien

    In northeastern Asia, the association of Synaptomys-like

    lemmings Plioctomys and mimomyian voles Cromeromys ex gr.

    irtyshensis-hordijki and smaller Mimomys sp. were found in the

    lower member of the Kutuyakh Formation at the Krestovka

    River in the Kolyma Lowland (Sher, 1987; Tesakov and van

    Kolfschoten, 2011). The assemblage is dominated by lem-

    mings and ‘Cromeromys’ voles, with Ochotona sp. and Mimomys

    sp. being less abundant.

    Several faunas of this age have been referred to the Central

    Asian subarea (Erbaeva and Alexeeva, 2000; Sotnikova et al.,

    1997; Vangengeim, 1977; Vislobokova et al., 1995). These

    include the Itanza fauna of Klochnevo I, II (Transbaikalia)

    with Ochotona intermedia, the ground squirrel Spermophilus

    itancinicus, Allactaga sp., the hamster Cricetinus varians, the

    voles Mimomys pseudintermedius, Clethrionomys sp., and

    ‘Villanyia’ klochnevi, the archaic mole rat Prosiphneus cf.

    paratingi, the first representative of the giant deer genus

    Praemegaceros and others, as well as the Kiikbai and Andyrgan

    faunas (southern Kazakhstan) with Ochotonoides complicidens,

    Mimomys pliocaenicus, the gerbil Meriones cf. meridianus,

    Equus stenonis, the camel Gigantocamelus longipes, and other

    forms.

    The fauna of Southern Tadzhikistan has affinities with the

    Eastern Mediterranean subarea and is characterized by a com-

    bination of Mediterranean and Central Asian forms. The rich

    assemblage from Kuruksay contained, along with A. gromovi

    and Mastodontoidea fam. et gen. indet., the baboon Papio

    sushkini (¼ Paradolichopitecus sushkini), the porcupine Hystrixsp., diverse carnivores including Nyctereutes megamastoides,

    eucyon ‘Canis’ kuruksaensis, Ursus cf. etruscus, the cursorial

    hyena Chasmaporthetes lunensis kani, Pliocrocuta perrieri, Lynx ex

    gr. issidorensis, Acinonys cf. pardinensis,Megantereon megantereon,

    and Homotherium crenatidens, the rhinoceros Stephanorhinus

    sp., the horse Equus stenonis pamirensis (¼ E. s. bactrianus),the camel Paracamelus praebactrianus, the deer Axis flerovi

    and Elaphurus eleonorae, the first representative of the giant

    deer genus Sinomegaceros (S. tadzhikistanis), the elk Libralces

    cf. gallicus, the giraffids Sogdianotherium kuruksaense and

    Sivatherium, and the antelopes Gazella parasinensis, Protoryx

    paralaticeps, Damalops palaeindicus, Gazellospira gromovae, and

    Antilospira sp., amongst others (Dmitrieva, 1977; Vangengeim

    et al., 1988). In this region, a large number of Asian elements

    occurred. Animals of dry, open landscapes (Ellobius, Pliocrocuta,

    Chasmaporthetes, Paracamelus, Equus) were accompanied by

    forest animals (bear, lynx, monkey, the deer Axis and Libralces)

    and savannah inhabitants (Sivatherium, Protoryx, Damalops,

    Gazellospira). Such a mixed composition reflected the mosaic

    landscapes and vertical zonality typical of mountainous

    regions. In Tadzhikistan, the local faunas attributed to this

    assemblage are known also from Obigarm, Karamaidan,

    Tutak, and Zil’fi localities, while faunas close to them in age

    were found in Kyrgyzstan (Akterek, Dzylgyndykoo) (Dmitrieva

    and Nesmeyanov, 1982; Sotnikova et al., 1997).

    The reversed polarity of the fossiliferous deposits in Khapry

    indicates that these sediments should be attributed to the lower

    part of the Matuyama Chron, together with analogous sites

    in Siberia and Central Asia (Podpusk-Lebyazh’e, Krestovka,

    Kuruksay) (Sotnikova et al., 1997; Tesakov et al., 2007;

    Vangengeim and Pevzner, 1991; Vangengeim et al., 1988;

    Vislobokova, 1996).

    Psekups mammal assemblage and its analogsThis stage is characterized by significant changes in the diver-

    sity of mammal communities (Figure 4). In Northern Eurasia,

    a cold-climate event around 2.2–1.9 Ma resulted in the appear-

    ance of new boreal elements, including some modern genera.

    In the European-Siberian subarea, Archidiskodon gromovi was

    replaced by the more progressive A. meridionalis (¼ Mam-muthus meridionalis), close to the type of the species from

    the Upper Valdarno, Italy. Voles of the genus Allophaiomys,

    the giant deer Praemegaceros, the elk Alces, the large bovids

    of the genus Bos and the Bison (Eobison) – B. (Bison) phyletic

    lineage, and the musk-ox Soergelia first appeared in this stage.

    In Psekups (Northern Ciscaucasia), Archidiskodon meridio-

    nalis, Eucladoceros orientalis (¼ Psekupsoceros orientalis, first rec-ognized as Cervus pliotarandoides), Stephanorhinus etruscus, and

    Equus stenonis were present (Alexeeva, 1977; Gromov, 1948;

    Vislobokova, 1990; and others). The small mammals included

    Borsodia newtoni-arankoides, Pitymimomys pitymyoides, Mimomys

    cf. pliocaenicus, Mimomys reidi, and Clethrionomys kretzoii

    (Alexandrova, 1976; Tesakov, 2004). These reversed polarity

    deposits correspond to the Matuyama Chron, between the

    Reunion and Olduvai Subchrons (Tesakov, 2004; Vangengeim

    and Pevzner, 1991). Slightly younger assemblages from the

    unrooted teeth Prolagurus and Lagurodon, and Allophaiomys deu-

    calion (Alexandrova, 1967; Rekovets and Nadachowski, 1995;

    Tesakov, 2004). The Odessa assemblage is subdivided into two

    phases: (1) an early phase, with the remains of rootless voles

    Allophaiomys deucalion and (2) a late phase, with the first cemen-

    ted rootless voles of Prolagurus (P. ternopolitanus) and Lagurodon

    (L. arankae) (Markova, 1982, 2007).

    In the Caucasus, the Dmanisi fauna is famous for the pres-

    ence of the first appearance in Eurasia of Homo, following

    dispersal from Africa. The remains of the Dmanisi hominins

    are attributed to the Homo erectus group and were found in the

    layers directly overlying a lava flow with a radiometric date of

    1.8�01 Ma, within the Olduvai Subchron. The fauna com-prises inhabitants of dry, open area (the tortoise Testudo, the

    ostrich Struthio, the gerbil Parameriones, the pika Ochotona, the

    hamster Cricetulus, A. meridionalis, Canis etruscus, Pliocrocuta

    Encyclopedia of Quaternary Scien

    cf. perrieri, Megantereon cultridens, Homotherium crenatidens,

    Palaeotragus) and forest animals (Bison (Eobison) georgicus, the

    deer Cervus abesalomi and Dama nestii, the bear Ursus etruscus)

    (Gabunia and Vekua, 1995; Hemmer et al., 2010; Vekua, 1995;

    Vekua and Lordkipanidze, 2008). The first occurrences of the

    ‘jaguar’ Panthera onca georgica and musk ox Soergelia are

    recorded there. The contemporaneous Palan-Tyukan fauna

    (Azerbaijan) includes Canis etruscus, Panthera ex gr. onca gom-

    baszoegensis, and Nyctereutes megamastoides.

    In Western Siberia, A. cf. meridionalis, Equus ex gr. stenonis,

    Alces sp., and Gazella sp. along with Borsodia ex gr. petenyii-

    hungaricus, andMimomys coelodus are known from the Podpusk

    fauna (from the uppermost part of the sands in the Irtysch

    River Basin) (Vislobokova, 1996). In southern Kazakhstan, the

    Aktogai (Kopaly) locality with Mimomys (Tcharynomys) haplo-

    dentatus (bed 3) and Allophaiomys deucalion (bed 7) also

    corresponds to this age (Sotnikova et al., 1997; Tjutkova and

    Kaipova, 1996).

    In the Kuznetsk Depression, Allophaiomys pliocaenicus, Pro-

    lagurus ex gr. pannonicus-posterius, Eolagurus argyropuloi, Archi-

    diskodon cf. meridionalis, and Ovibovini gen. indet. were found

    in the Mokhovo Formation, 1.8–1.2 Ma (Foronova, 2001).

    In northeastern Asia, a tooth of Archidiskodon meridionalis

    meridionalis was found in the Vilyuisk district, Yakutia; the find

    confirmed the spread of the subspecies into North America

    over the Bering land bridge (Dubrovo, 1990), probably at the

    end of the 2.9–2 Ma global sea level fall.

    In Transbaikalia, the Dodogol and Zasuchino II faunas

    have been referred to the Central Asian subarea. In Dodogol,

    Borsodia laguroformes, Allophaiomys cf. pliocaenicus, Prosiphneus

    youngi, the first woolly rhino Coelodonta (of Asian origin),

    Equus ex gr. sanmeniensis, and others were present (Vangengeim,

    1977). The revised data on the Pleistocene small mammals of

    the region are presented in Alexeeva et al. (2007) and Alexeeva

    and Erbaeva (2008).

    Terminal Early Pleistocene: Early Galerian, 1.2–0.8 Ma

    The time range from 1.2 to 1.1 Ma (before the Jaramillo paleo-

    magnetic reversal) is an important boundary in the history of

    the biota, and is reflected in the nomenclature of stratigraphic

    schemes (the Villafranchian–Galerian boundary or the Early–

    Late Eopleistocene boundary in the scheme of the Russian

    Stratigraphic Committee).

    Tamanian mammal assemblage and its analogs(Nogaisky–Morozovka, ¼ Menapian–Bavelian)This stage is characterized by the replacement of Archidiskodon

    meridionalis meridionalis by the more advanced A. meridionalis

    tamanensis, the first appearance of the giant deer Praemegaceros

    verticornis and Megaloceros, the red deer Cervus (Cervus) acoro-

    natus, the roe deer Capreolus cf. suessenbornensis, the broad-

    fronted elk Alces latifrons, the bison Bison (Bison), camels of

    the genus Camel, the first occurrence of the woodland elephant

    Palaeoloxodon and woodland antelopes Tragelaphus and

    Pontoceros, and the presence of Paracamelus (P. kujalnensis)

    (Alexeeva, 1977; Gromov, 1948; Vekua, 1962; Vereshchagin,

    1957; and others). From the end of the early to the middle

    Pleistocene, true wolves attributed to the Canis mosbachensis–

    C. variabilis group and large hunting dogs Lycaon lycaonoides

    (¼ Canis (Xenocyon) lycaonoides) existed in Eurasia fromWesternEurope to Transbaikalia andChina (Sotnikova and Rook, 2010).

    The Tamanian mammal assemblage is based on the fauna

    of Synaya Balka (type locality) and Tsymbal in the Taman

    Peninsula. A. meridionalis tamanensis coexisted in the North

    Black Sea area with Homotherium crenatidens, the short-faced

    hyena Pachycrocuta brevirostris, the horse Equus suessenbornensis,

    the rhinoceroses Stephanorhinus etruscus and Elasmotherium

    caucasicum, and others (Alexeeva, 1977; Sotnikova and Titov,

    2009; Vereshchagin, 1959; Figure 5). Vereshchagin (1957)

    also identified the potential impact of early hominins on

    some of these assemblages. And recently, stone artifacts of the

    Oldowan type were reported from the Synyaya Balka site by

    Shchelinsky et al. (2010). In the Asian part of the territory, the

    first reliable evidence of human activity comes from the stone

    tool assemblage of Kuldara (Ranov et al., 1995) dated to

    Encyclopedia of Quaternary Scienc

    0.8 Ma and broadly synchronous with stone tools from the

    Karama site in the Altai region (Derevyanko and Shunkov,

    2005).

    Morozovkian small mammal fauna with more derived

    voles Microtus (Stenocranius) hintoni and the pitymyoid Micro-

    tus sp. are correlated with these assemblages (Alexandrova,

    1976; Rekovets and Nadachowski, 1995). The small mammal

    fauna of this stage are also represented in the Dnieper, Dnies-

    ter, and Don basins (Agadjanian, 2009; Alexandrova, 1976;

    Markova, 2007; Tesakov et al., 2007; Topachevsky et al.,

    1987; and others). The assemblages include an advanced

    meadow vole Allophaiomys (A. pliocaenicus) and the steppe

    lemmings Prolagurus pannonicus, Lagurodon arankae, and Eola-

    gurus argyropuloi.

    At this time, differentiation of environment sharply

    increased. In the Caucasus (Akhalkalaki, Georgia), the most

    thermophilous elements continued to exist, including Hippopot-

    amus georgicus, Equus suessenbornensis, and Stephanorhinus hund-

    sheimensis, the cave or ‘spelaeoid’ bear close to U. deningeri, and

    the first jaguar (close to P. onca gomboszoegensis) (Hemmer et al.,

    2010; Vekua, 1962, 1986). In Siberia, the diversity ofmusk-oxen

    increased. The ovibovine Soergelia occurred in the Razdolie as-

    semblage (Western Siberia) with A. meridionalis, Palaeoloxodon

    sp., Equus (Allohippus) sp., Bison sp., and Ovibovini (Vangen-

    geim, 1977). The remains of Soergelia and the oldest members

    of Praeovibos were found in the early stage of the Olyorian land

    mammal age (Beringia, Bering Province) (1.4–0.8 Ma) together

    with those of the first wolverine Gulo minor (¼ G. cf. schlosseri)(Sher, 1971, 1987; Sher et al., 2011; Vangengeim, 1977). These

    co-occurred with Archidiskodon sp., Lycaon lycanoides, Equus

    (Plesippus) verae, Alces sp., Bison sp., and others. The northern-

    most finding of Homotherium in Asia is associated with this

    fauna. In Eastern Siberia, the Aldan fauna included a number

    of forest inhabitants (Trogontherium cf. cuvieri, Palaeoloxodon ex

    gr. namadicus, Alces latifrons, and Microtus gregaloides). In Trans-

    baikalia, the Kudun (Kizhing–Kudun depression) and Zasu-

    khino (Itanza River basin) correspond to the youngest part of

    the early Pleistocene and are correlated with the uppermost

    Matuyama Chron (Erbaeva and Alexeeva, 2000).

    The oldest Camelus (C. cf. knoblochi) coexisted with the

    giant deer Praemegaceros (close to P. verticornis) in southern

    e, (2013), vol. 4, pp. 605-614

    Tadjikistan (Lakhuti locality, the uppermost part of the

    Matuyama) and members of diverse habitats. They included

    inhabitants of open, dry, and savannah-like landscapes, such

    as the gerbil Meriones lacutensis and mole vole Ellobius lakhu-

    tensis, Archidiskodon sp., Equus cf. namadicus, and Canis cf.

    mosbachensis, in association with a large Lycaon, Pachycrocuta

    brevirostris,Homotherium sp., the red-backed vole Clethrionomys,

    Panthera onca gomboszoegensis, the badgerMeles ex gr.meles, and

    the giant deer Sinomegaceros sp. (Sotnikova, 1989; Sotnikova

    and Vislobokova, 1990). Small mammals also included white-

    toothed shrew Crocidura sp., a hamster Cricetulus sp., the

    meadow voles Allophaiomys sp., and Microtus (Phaiomys) lachu-

    tensis (data from Zazhigin).

    Faunas intermediate in age between the Tamanian and

    Tiraspolian faunas are known from the lower course of the

    Dnester River (Karai-Dubina) and in the middle Don (Petro-

    pavlovka) area and have been studied in detail (Agadjanian,

    2009; Markova, 2007). The reversed polarity deposits contain

    the remains of Prolagurus and pitymyoid Microtus, the last

    representatives of Allophaiomys, and the oldest Microtus with

    five closed enamel triangles in the first lower molar.

    The dispersal of mammals out of Northern Eurasia in-

    creased from about 1.2 to 1.1 Ma; Praemegaceros verticornis

    and Soergelia invaded Western Europe and Homo erectus and

    Sinomegaceros first occurred in China (Kahlke et al., 2011; Qiu,

    2006).

    Encyclopedia of Quaternary Scien

    Early Middle Pleistocene: Middle–Late Galerian, ¼Cromerian–Elsterian, 0.8–0.4 Ma

    The early–middle Pleistocene boundary of the standard

    scheme corresponds to the Eopleistocene–Neopleistocene

    boundary of the Russian stratigraphic scheme and the Early–

    Middle Galerian boundary in Italy.

    Tiraspolian mammal assemblages and its analogsThe considerable reorganization in the composition of mam-

    malian communities was related to a drop in temperature

    at the early–middle Pleistocene boundary, with a notable

    increase in amplitude of climatic oscillations. Along with

    progressive cooling, climatic fluctuations changed from 41-ka

    low-amplitude cycles to a 100-ka high-amplitude cycle

    (Shackleton, 1995). In the Russian Plain, three periods of

    glaciation correspond to this stage (Pokrovka, Don, and Oka).

    The climatic zonation of the northern Eurasian landscape

    began to resemble that of the present day (Figure 6). Archidis-

    kodon was replaced by the mammoth Mammuthus trogontherii

    (¼ A. wüsti) and the proportion of modern vertebrate generasharply increased.

    The representatives of the Tiraspolian mammal assemblage

    in southeastern Europe existed under a temperate climatic

    regime in a variety of landscapes, dominated by forest-steppes

    (Alexeeva, 1977). Kolkotova Balka (near Tiraspol) is the type

    locality of this assemblage. The fossil remains were found in

    the so-called ‘Tiraspolian gravels’ (fluvial deposits of the Dnies-

    ter 6th terrace). Horses were represented by both caballoid

    (Equus cf. mosbachensis) and stenonis (E. aff. suessenbornensis)

    forms. Mammuthus trogontherii, Stephanorhinus etruscus (late

    form), the large deer Cervus acoronatus, Praemegaceros verticor-

    nis, the fallow deer Praedama and Alces latifrons, and a short-

    horned bison Bison schoetensacki are common to both the

    Tiraspolian fauna and the fauna of Western Europe (Kahlke

    et al., 2011; Nikiforova, 1971). Two skeletons ofM. trogontherii

    were found in the Kagalnik sand pit (Azov). Data on small

    mammal fauna represent several phases of Tiraspolian mam-

    mal assemblages (see Markova, 2007). A considerable cooling

    has been recognized in the southern part of European Russia at

    the time of the early middle Pleistocene Don glaciations,

    highlighted by the presence of subarctic species such as the

    lemmings Lemmus ex. gr. Sibiricus and Dicrostonyx sp. and the

    North Siberian vole Microtus ex gr. hyperboreus (Agadjanian,

    2009).

    The southward shifting of ranges, with persistence of some

    forms in refugia (including mountain ones), was usual during

    continental glaciations. Very diverse mammal faunas are

    known from the northern Caucasus. Most are associated with

    Early Paleolithic sites and stone artifacts of Acheulian type. The

    taxa include the macaque monkey Macaca cf. sylvana, the spot-

    ted hyena Crocuta spelaea, diverse bears including cave bear

    Ursus deningeri (dominant), black bear Ursus ex gr. thibetanus

    probably related toU. etruscus, and the small cave bearU. savini

    rossicus (¼ U. aff. spelaeus rossicus), the cave lion Panthera spelaeaand leopard P. pardus, the gray wolf Canis lupus, the fox Vulpes

    vulpes, Stephanorhinus,Megaloceros giganteus, Capreolus cf. suessen-

    bornensis, Bison cf. schoetensacki, together with typical montane

    genera such as the ibex Rupicapra and the goat Capra.

    The fauna of the late stage of the Olyorian faunal assem-

    blage (West Bering Province) are characteristic of tundra and

    forest–tundra environments and cold climatic conditions sim-

    ilar to modern ones (Sher, 1971, 1987; Vangengeim, 1977).

    This fauna included the first reindeer Rangifer. Alces aff. latifrons

    and Bison sp. were also present in the artiodactyl community.

    Rangifer is also recorded in the early middle Pleistocene of the

    Kuznetsk Depression (Foronova, 2001).

    In Transbaikalia, the Tologoi assemblage contained the

    woolly rhino Coelodonta tologoijensis, Equus ex gr. sanmeniensis,

    Cervus ex gr. elaphus, Spirocerus cf. peii, and Bison sp.

    (Vangengeim, 1977). Cryogenic disturbance at the base of the

    deposits is associated with remains from the Zasuhino assem-

    blages (Zasuhino 3, 1–0.78 Ma) and in Tologoi 2 beneath the

    Brunhes–Matuyama magnetic reversal, above the Jaramillo

    (Alexeeva, 2005). The fauna is characterized by a large diversity

    of carnivores and ungulates: Nyctereutes sp., Canis variabilis,

    Lycon cf. lycaonoides (¼ Xenocyon lycaonoides), Ursus sp., Gulosp., Pachycrocuta brevirostris, Homotherium sp., the large-sized

    tiger Panthera ex gr. tigris, Coelodonta tologojensis, Equus ex gr.

    sanmeniensis, Equus ex gr. suessenbornensis–verae, Alces cf.

    latifrons, and others (Vangengeim et al., 1990). Zasuhino 3

    locality also has yielded Cervus sp., Megacerini indet, Capreolus

    cf. suessenbornensis, Ovibovini indet., and Bison sp.

    At the boundary of the early and middle Pleistocene, a

    prominent climatic deterioration was marked over northern

    and central Eurasia and many immigrants from these regions

    are recorded in Western Europe. The Bering land bridge (0.8–

    0.011 Ma) further facilitated faunal exchanges between North-

    ern Asia and North America.

    Late Middle Pleistocene, ¼ Aurelian, ¼ Holsteinian–Saalian,0.4–0.126 Ma

    Singilian and Khasarian faunas and their analogsThe Singilian fauna and its analogs are related to the Likhvin

    interstadial (¼ Mindel-Riss, ¼ Holsteinian), one of the mostpronounced warm stages in the middle Pleistocene. In Eastern

    Europe, the Singilian faunas were represented by the straight-

    tusked elephant Palaeoloxodon antiquus and Merck’s rhinoceros

    Stephanorhinus kirchbergensis. In the south of Northern Eurasia,

    gray wolf (Canis lupus), Camelus knoblochi, Megaloceros gigan-

    teus, and Bison priscus longicornis became widespread after

    the mid-middle Pleistocene (Alexeeva, 1977; Gromov, 1948).

    Typical small mammals include the water vole Arvicola mosba-

    chensis, the yellow steppe lemming Eolagurus luteus, the narrow-

    skulled vole Microtus gregalis, the northern or root vole

    M. oeconomus, Ellobius, and the ground squirrel Spermophilus

    (Markova, 2007). In Western Siberia, Palaeoloxodon coexisted

    with Equus cf. steinheimensis, a small-sized cave bearUrsus savini

    rossicus (¼ Ursus spelaeus rossicus), and the giant deer Megalo-ceros giganteus during the contemporaneous Tobol interstadial

    (Vangengeim, 1977; Figure 7). From this time onward

    (�400 ka), the giant deer became widespread in the temperatelatitudes of Eurasia, together with modern deer species (red

    deer Cervus elaphus and the reindeer Rangifer tarandus).

    The Khasarian faunal assemblage (Dnepr glaciation) with

    its type locality at Cherny Yar (Volga River Basin) contained

    Mammuthus trogontherii chosaricus (ancestor of the woolly

    mammoth Mammuthus primigenius), Panthera spelaea, Elas-

    motherium sibiricum, the woolly rhinoceros Coelodonta antiqui-

    tatis, Equus chosaricus, Camelus knoblochi, the long-horned bison

    Bison priscus longicornis, Megaloceros giganteus, and modern

    genera and species, including Cervus elaphus, Rangifer tarandus,

    the musk-oxen Ovibos, the saiga antelope Saiga, etc., the water

    vole Arvicola chosaricus, and a diverse assemblage of steppe-

    adapted small mammals (Alexandrova, 1976; Dubrovo, 1985;

    Gromov, 1948). The fauna existed in the colder and drier

    climate of the periglacial forest-steppe along the southernmargin

    of the continental Dnieper glaciation (Riss, RI) (Vangengeim,

    1977). However, localities rich in large mammal are rather

    rare. In the south of the Russian Plain, typical subarctic and

    steppe smallmammals occurred (Dicrostonyx simplicior, Lemmus

    sibiricus, Lagurus ex gr. lagurus, Microtus gregalis). In the

    Caucasus region, the tar pit Binagady fauna near Baky belongs

    to the same stage. Under modern conditions, the range of some

    animals became completely separated and confined to different

    biomes.

    Conclusions

    The data on the early and middle Pleistocene mammals from

    Northern Eurasia offer important insights into our knowledge

    of the history of mammals. These assemblages differ consider-

    ably in their composition as a result of evolutionary and mi-

    gration processes. In the Pleistocene, the general trend toward

    global temperature decrease, changes in landscape and climatic

    conditions, and differentiated environmental patterns caused

    important changes in mammal communities within the terri-

    tory at the suprageneric, generic, and species levels. The faunas

    demonstrate adaptation from the temperate climatic condi-

    tions of the pre-Pleistocene to the cooler and more diverse

    conditions at the end of the Pleistocene. A gradual disappear-

    ance is therefore noted of the Miocene–Pliocene and ther-

    mophilous forms (mastodons, giraffids, hippopotamids,

    hyenids) with their extinction or displacement to southern

    Asia or Africa, paralleled by the development of Pleistocene

    and modern genera and species, and the gradual emergence of

    associations typical for modern biomes (tundra, steppes, for-

    est, etc.).

    The main periods of turnover in mammal communities of

    Northern Eurasia coincided approximately with the maximum

    drops in global temperature, which were accompanied by

    large-scale transformations of the environment. The most sig-

    nificant changes occurred at the Pliocene–Pleistocene (2.6 Ma)

    and early–middle Pleistocene (0.8 Ma) boundaries. Changes

    in faunal composition were also reported at 1.8, 1.2, and

    0.4 Ma. Beginning in the middle Pleistocene, the turnover

    affected mammal diversity at the generic and species levels.

    Immigration to and from adjacent territories played an impor-

    tant role in these faunal transformations.

    The roots of some modern genera are found in the late

    Miocene (Canis, Axis, etc.), the Pliocene (Nyctereutes, Ursus,

    Lynx, Equus), the Gelasian (Gulo, Cervus, Alces, Capreolus,

    Bison), and the middle Pleistocene (Camelus, Rangifer, Ovibos,

    Saiga). The Pliocene–Pleistocene boundary is marked by the

    disappearance of a number of thermophilous forms. Evolu-

    tionary trends can be traced equally in the large herbivorous

    animals (elephants, rhinoceroses, horses, artiodactyls), various

    carnivores (canids, ursids, hyenids, felids), and small mam-

    mals. A clear boreal group, which comprised the ancestral

    forms of modern Northern Eurasian species, started to form

    actively at the beginning of the late early Pleistocene, around

    1.8 Ma. The increasing amplitude of global cooling was then

    accompanied by the appearance and widespread distributions

    of first boreal and then arctic forms in northern Siberia and the

    mountainous regions of Central Asia. Boreal communities

    Encyclopedia of Quaternary Scien

    became more widespread in the early middle Pleistocene

    (true wolves, tiger Panthera tigris) and at the end of late middle

    Pleistocene (Khasarian), with the first appearance of modern

    species (Cervus elaphus, Rangifer tarandus, Ovibos, Saiga, etc.).

    Zoogeographic provinciality therefore increased from the Early

    toward the late middle Pleistocene.
