ut poorly studied. Dimorphism (or trimorphism?)has been present since the Early Permianin Robustoschwagerina, Anderssonites,Rugofusulina and Ruzhenzevites, and perhapsAlpinoschwagerina (formerly Pseudoschwagerina)and Zellia. Among the foraminifera, theschwagerinoids are probably the first group inwhich the trimorphic reproduction cycle becamecommon; this group may also have been the firstwhich lived in endosymbiosis with algae. Thedimorphism or trimorphism is especially conspicuousin the advanced schwagerinoids Parafusulina,Skinnerina, Eopolydiexodina andPolydiexodina. The life cycle of Eopolydiexodinais reconstructed to include cycles of gamonts,agamonts and schizonts, and the embryonic apparatus-bearingforms may correspond to thegamont A2 generation.2008040151北 欧 盐 沼 中 有 孔 虫 Trochammina inflata 包 括三 态 性 的 生 活 周 期 变 化 = Life cycle variationincluding trimorphism in the foraminifer Trochamminainflata from north European saltmarshes. ( 英 文 ). Lehmann G; Röttger R. Journalof Foraminiferal Research, 2006, 36(4):279-290 1 图 版 .The proloculus diameters were analyzed in 15samples of 200 individuals each of the agglutinatedforaminifer TTrochammina inflata fromfive salt marsh localities in Germany, Denmarkand Sweden. Accumulations of dead specimensfrom the uppermost centimeter of sediment betweenthe roots of salt marsh halophytes includemicrospheric and, as revealed by statisticalanalyses, two classes of megalospheric individuals.These size classes are consistent with theoccurrence of three generations in a trimorphiclife cycle as has been described in several otherforaminiferal taxa, and they support the interpretationof a biologically trimorphic life cycle inTrochammina inflata. The three size classes ofproloculi correlate with: agamonts (microspherictests), schizonts (smaller megalospheric tests)and gamonts (larger megalospheric tests). Thisinterpretation, however, has not been confirmedby studies on cultivated specimens. Other factorsthat may cause the bimodal size distribution ofthe megalospheric proloculi are discussed. Thesample means of the agamonts range from 16.1–22 µm, those of the supposed schizonts from28.6–34.2 µm and those of the supposed gamontsfrom 36.5–41.7 µm. The proportions ofthe three generations are used to infer long-termlife cycles in time-averaged assemblages. Samplesfrom Bottsand (Kiel Bight, Germany) containparticularly high proportions of schizonts,indicating that schizogony may be the dominantor sole mode of reproduction at the latter sites.Proportions of gamonts are relatively high in theHeden saltmarsh (Swedish west coast) and in theremaining localities, indicating a higher incidenceof the dimorphic cycle, relative to the trimorphiccycle. A varying importance of the respectivemode of reproduction results in differingproportions of reproductive products, agamonts,gamonts and schizonts in the sediment.Previous investigations have focussed on trimorphismin tropical environments; herein, we presentan example from temperate supralittoralsemiterrestrialhabitats subject to strong fluctuationsin water content, temperature and salinity.2008040152中 白 垩 世 Albian 末 期 至 Cenomanian 初 期 具经 向 壳 纹 的 浮 游 有 孔 虫 的 一 新 属Paracostellagerina = Paracostellagerina now.gen., a meridionally costellate planktonic foraminiferalgenus of the Middle Cretaceous (latestAlbian-earliest Cenomanian). ( 英 文 ). GeorgescuM D; Huber B T. Journal of ForaminiferalResearch, 2006, 36(4): 368-373 2 图 版 .A new genus is proposed to accommodatestrongly ornamented hedbergellids of the latestAlbian-earliest Cenomanian. Paracostellagerinanov. gen. is characterized by asymmetrical testornamentation, rugosities, and costellae that aremeridionally arranged on the umbilical side andparallel to the periphery on the spiral side. Thisgenus has a global distribution within tropicalsubtropicallatitudes and, because of its shortstratigraphic range, it is a valuable biomarker forcorrelation of uppermost Albian-lowermostCenomanian sequences.2008040153Mornod 1949 描 述 的 Thalmanninella reicheli和 Rotalipora montsalvensis 所 遗 失 的 模 式 标本 的 扫 描 电 子 显 微 镜 记 录 = Scanning electronmicroscope documentation of the lost holotypesof Mornod, 1949: Thalmanninella reicheli andRotalipora montsalvensis. ( 英 文 ). Caron M;Spezzaferri S. Journal of Foraminiferal Research,2006, 36(4): 374-378 2 图 版 .The species Globotruncana (Rotalipora)reicheli and Gobotruncana (Rotalipora) montsalvensis,were established in 1949 by Mornod.The two holotypes were figured only by drawingsand the specimens were never made publiclyavailable. Since their first description, thesetwo species have acquired great importance asbiostratigraphic markers. However, holotypeshad been considered as lost and neotypes wereestablished and described. Recently, these holotypeswere discovered. We present here for thefirst time Scanning Electron Microscope imagesof the holotypes and compare them with theoriginal drawings and neotypes to highlight possiblesimilarities and differences.
