are described in detail, and the local stratigraphicranges and persistence of biostratigraphicallyimportant radiolarian species are documented.The spumellarian component is published for thefirst time, and four new species are described:Albaillella kayai n. sp., Ceratoikiscum jucundumn. sp., Meschedea akcetensis n. sp., and Stigmosphaerostylusistanbulensis n. sp. Two assemblagesare recognized: the A. paradoxa andthe A. sp. aff. A. undulata-A. deflandrei assemblage.The older A. paradoxa assemblage containsTraenosphaera sicarius, Pararchocyrtiumserrensis, Cyrtisphaeractenium mendax, andcommon to abundant A. paradoxa and Popofskyellium.Albaillella paradoxa is not restrictedto the older assemblage but is the only species ofAlbaillella present. The younger A. sp. aff. A.undulata-A. deflandrei assemblage contains eitherA. sp. aff. A. undulata or A. deflandrei. Albaillellaindensis ambigua, A. kayai n. sp., andKantollium sp. A occur exclusively in the A. sp.aff. A. undulata-A. deflandrei assemblage, butare rare and patchy in their occurrence. Distinctivetaxa common to both assemblages are Archocyrtiumlagabriellei, Pylentonema antiqua,C. avimexpectens, C. umbraculatum, C. jucundumn. sp., Trilonche palimbola, M. akcetensis n.sp., S. tortispina, Polyentactinia polygonia, P.aranea, and Cubaxonium? octaedrospongiosum.Many of the taxa present occur in middle andupper Tournasian sections from France, the centralPyrenees, and Germany and provide a solidbasis for re-assessing the age of the BaltalimaniFormation as middle to late Tournasian (Tn2–Tn3).2008040305墨 西 哥 西 北 部 索 诺 拉 宾 夕 法 尼 亚 亚 系 蜓 类 和钙 藻 及 其 生 物 地 层 和 生 物 地 理 意 义 = Pennsylvanianfusulinids and calcareous algae fromSonora (northwestern Mexico), and their biostratigraphicand palaeobiogeographic implications.( 英 文 ). Gomez-Espinosa C; Vachard D;Buitrón-Sánchez B; Almazán-Vazquez E; Mendoza-MaderaC. Comptes Rendus Palevol, 2008,7(5): 259-268Pennsylvanian carbonates are widespread inSonora (Mexico) and contain a diverse biota offoraminifers and calcareous algae. Detailed studieshere are devoted to the outcrops of the SierraAgua Verde and Cerro El Tule. The Late Atokan(early Late Moscovian part), Desmoinesian(= late Late Moscovian) and Missourian(= Kasimovian) stages are especially rich infusulinids and algae. The principal zones offusulinids of Wilde encountered are A3, DS1and MC1–2. New data are given about the generaFusulinella, Parawedekindellina, Zellerella,Komia and Paraepimastopora, in order to establishmigrations or vicariances between Mexicoand Palaeotethys2008040306帕 米 尔 东 南 部 下 三 叠 统 - 中 安 尼 阶 卡 拉 塔 什群 有 孔 虫 和 地 层 = Foraminifers and stratigraphyof the Karatash Group (lower Triassic-Middle Anisian), the southeastern Pamir. ( 英 文 ).Korchagin O A. Stratigraphy and GeologicalCorrelation, 2008, 16(3): 248-256First data on Middle Triassic foraminifers ofthe southeastern Pamir are considered. Thelower-middle Anisian sediments are reliablyrecognized within uniform limestone successionof the Karatash Group in the Southeastern Pamirbased on found foraminiferal species Meandrospiradeformata Salaj, Meandrospira cheni (Ho),Pilamminella ex gr. semiplana (Kochansky-Devide et Pantic), and Endotheba badouxi (Zaninettiet Bronnimann). The lower-middle AnisianMeandrospira deformata Zone is definedand the Karatash Group is subdivided into theKhan (lower) and Yulla (upper) formations. Theforaminifers found imply their migration betweenthe western (Alps, Carpathians, Balkans)and eastern (South China platform, Malaysia,Japan) Tethys across the southeastern Pamir region.Characteristic species of the genus Meandrospirarecorded in the southeastern Pamirs aredescribed with specifying their taxonomic scope.2008040307俄 罗 斯 白 令 海 南 部 浮 游 有 孔 虫 : 在 晚 更 新 世 -全 新 世 时 期 组 分 和 数 量 的 变 化 = Planktonicforaminifers in the southern Bering Sea:Changes in composition and productivity duringthe Late Pleistocene-Holocene.

Stratigraphy and GeologicalCorrelation, 2008, 16(3): 328-342Taxonomic composition and distribution ofplanktonic foraminifers are studied in section ofCore GC-11 that penetrated through Upper Quaternarysediments of the Bowers Ridge westernslope, the southern Bering Sea. As is shown,structure of foraminiferal assemblage and productivityhave varied substantially during thelast 32000 calendar years in response to changesin surface water temperatures and water masscirculation in the northern part of the Pacific, theBering Sea included. The productivity wasmaximal during deglaciation epoch, being notablylower in the Holocene and minimal at theglaciation time.2008040308丹 尼 阶 最 下 部 浮 游 有 孔 虫 新 属 Palaeoglobigerina的 形 态 、 生 物 统 计 和 系 统 分 类 研 究 =Morphology, biometry and taxonomy of the99
