litic biozones lower than their FAD in shallowerwater facies on the Yangtze Platform. Later inthe late Floian, these genera became major componentsof the Sinorthis fauna that flourishedover much of the Yangtze Platform, suggesting amigration of the benthic shelly fauna from slopeto platform facies during the Floian radiation inSouth China. Compared to the platform fauna,the deep-water brachiopod fauna of the Sanduarea has a lower level of richness, diversity, andcommunity organization. Three brachiopod associationsare recognized: the Paralenorthis-Nereidella, the Palaeoglossa longa, and the Lingulella-Protoskenidioidesassociations. An upsectiondecrease in shell size, faunal richness,and species diversity in the Tonggao Formationindicate a deteriorating environment towardshypersalinity in the Sandu area, resulting in theultimate disappearance of the deep-waterbrachiopod fauna.2008040343环 境 对 加 拿 大 东 部 安 提 库 斯 塔 岛 早 志 留 世 五房 贝 腕 足 动 物 群 落 时 空 变 化 的 控 制 = Environmentalcontrol on temporal and spatial differentiationof Early Silurian pentameride brachiopodcommunities, Anticosti Island, eastern Canada.( 英 文 ). Jin Jisuo. Canadian Journal ofEarth Sciences, 2008, 45(2): 159-187The Early Silurian carbonate succession ofAnticosti Island, eastern Canada, contains a richand diverse pentameride brachiopod fauna. Multivariateanalyses of 91 samples (total 17 230specimens) confirm a high degree of temporalsegregation but only moderate spatial differentiationof the Virgiana, Pentamerus, Stricklandia,Ehlersella, Microcardinalia, and Clorindacommunities. Most pentameride communitiesshow a wider range of water depth than previouslybelieved. The V. barrandei Communityoccupied a substrate setting from lower BA2 toupper BA3, whereas the V. mayvillensis Communitylived mainly in BA4. The P. oblongusCommunity preferred a BA3 setting, comparableto the classic Pentamerus Community, but the P.palaformis Community was predominantly BA4.The stricklandiid communities have a high βdiversity, dominated by various species ofStricklandia, Ehlersella, Microcardinalia, andKulumbella, and occurred most commonly inBA4, but could extend to BA3 environments.The Clorinda Community of Anticosti Islandpreferred deep and quiet water settings, comparableto its widely accepted BA5 assignmentelsewhere. At the generic level, the Virgiana,Pentamerus, and the stricklandiid communitieshave a largely overlapping BA range, but a clearstratigraphical separation. Thus, their temporalalternations were not likely controlled by waterdepth, water turbulence, or substrate conditions,but by fluctuating ocean water temperature, assuggested by chemostratigraphical and paleobiogeographicalevidence.2008040344加 拿 大 东 部 安 提 库 斯 塔 岛 早 志 留 世 兰 多 维 列统 正 形 贝 腕 足 动 物 组 合 = Llandovery (EarlySilurian) orthide brachiopod associations fromAnticosti Island, eastern Canada. ( 英 文 ). LiRong-Yu; Allen T. Canadian Journal of EarthSciences, 2008, 45(2): 189-201Five Llandovery orthide brachiopod associations,through cluster analysis, are delineated onAnticosti Island. The Levenea-Dicoelosia Association(A), occurring in the Goéland andRichardson members of the lower Jupiter Formation,represents a deep-water setting aroundor below the maximum storm wave base. TheFlabellitesia-Dalejina Association (B), appearingin the Cybèle, Ferrum, and Pavillon membersof the upper Jupiter Formation, indicateswater depth in between the maximum and normalstorm wave bases. The Isorthis (Ovalella)Association (C 1 ), present in the Fox Point Memberof Becscie Formation, corresponds to theshallower water setting around the normal stormwave base. The Mendacella bleikeriensis Association(C 2 ), occurring in the Innommée, Sandtop,and Macgilvray members of Gun RiverFormation, characterizes the water depth slightlybelow the normal storm wave base. The Mendacellaudauberis Association (D), appearing inthe Merrimack Formation, signifies a waterdepth around the maximum storm wave base.The water depth indication of these associationsmay bear potential as future reference for otherregions, but attention should be paid to the specieslevel as some congeneric species can belongto different associations of different depth. Thecluster analysis on orthide collections based onbinary data demonstrates that statistical methods,Jaccard coefficient and Ward's method of clustering,are practical and effective to delineatelarge brachiopod collections on Anticosti Island.2008040345华 南 早 三 叠 世 腕 足 动 物 舌 形 贝 类 新 属 和 新 种= New Early Triassic Lingulidae (Brachiopoda)genera and species from South China.
