microstructure of septa resembling that of theScleractinia, the genus was originally ascribed toa rare group of corals informally referred to assleractiniamorphs, previously known from theOrdovician and Permian. Here, we report Furcophylliashaitanica sp. nov. from limestoneboulders found in the volcano-clastic deposits ofthe upper Ladinian Sajtan suite of the SouthEastern Pamirs. A new species of Furcophylliasignifies that the genus was a faunal elementwidely distributed in the Tethys.2008040333中 国 早 寒 武 世 澄 江 地 层 Palaeoscolecid 蠕 虫Cricocosmia 和 Tabelliscolex 属 的 躯 干 纹 饰 =Trunk ornament on the palaeoscolecid wormsCricocosmia and Tabelliscoles from the EarlyCambrian Chengjiang deposits of China.

Acta palaeontologicaPolonica, 2007, 52(2): 423-431New observation reveals that the ventral trunkbears an additional set of ventral sclerites whilethe lateral sclerited display a tubercle-bearing(inner surface) and net-like (outer surface) microstructuresimilar to that of Tabelliscolexhaxagonus. (1) Cricocosmia shows a dorsoventraland antero-posterior differentiation intrunk ornament; (2) as seen from the microstructure,Cricocosmia is close to Tabelliscolexhexagonus, supporting the idea that lobopodiansand arthropods, both of which show an uppercapping layer in the outer sclerites, are moreclosely related than the palaeoscolecidans; and(3) the similarities among the scalids, pharyngealteeth and the trunk spines of palaeoscolecidansare superficial. Tabelliscolex maanshanensis sp.nov., characterized by an inner concentric circletof laminae in each tubercle of the lateral trunkplate, is proposed herein. Element mapping revealthat four known pathways of preservationcan be found co-occurring in a single specimenof Cricocosmia or Tabelliscolex, which shedsnew light on the preservation of the Chengjiangfossils.2008040334加 拿 大 Manitoba 南 部 上 奥 陶 统 床 板 珊 瑚Manipora 的 形 态 特 征 = Morphometrics ofManipora (tabulata: Upper Ordovician: southernManitoba, Canada). ( 英 文 ). Bae B-Y; Elias R J;Lee D-J. Journal of Paleontology, 2008, 82(1):78-90 1 图 版 .Multivariate morphometric analysis was appliedfor differentiation of closely related speciesand evaluation of intra- and interspecific variationin Manipora from the Selkirk Member, RedRiver Formation, in southern Manitoba. Sevenmorphological characters were quantified intransverse thin sections of 46 coralla and statisticallytested for selecting effective characters indiscriminating species. Cluster analysis was performedon a raw data matrix coordinated with 46coralla by three selected characters. Two majorclusters on the resulting dendrogram were regardedas morphospecies, following comparativeexamination of the coralla using serial sections.Cluster analyses were also conducted on principalcomponent score matrices obtained from theraw data set coordinated with 46 coralla by allseven characters, and from an experimental dataset including the 46 coralla plus two replicates ofeach and six of the characters. The results agreeclosely with the first cluster analysis, but discriminationof morphospecies was slightly degraded.The validity of two morphospecies recognizedin the first cluster analysis was verifiedby discriminant analyses, descriptive statistics,and bivariate plots. The results show that tabulariumarea is the most meaningful character fordistinguishing these morphospecies; ranges ofvariations of the other six characters overlapbetween morphospecies. Another cluster analysislike the first was performed, but with the additionof 11 type specimens and reference corallaof Manipora species from the Upper Ordovicianof southern and northern Manitoba and Texas.Based on this analysis, together with comparativeexamination of thin sections, the two morphospeciesare identified as valid species: M.amicarum Sinclair, 1955 and M. manitoba(Sokolov, 1955). Manipora magna Flower, 1961is considered to be a synonym of M. amicarum,while M. trapezoidalis Flower, 1961 and M. garsonensisCaramanica, 1992 are considered to besynonyms of M. manitoba, and the hypotypes ofM. amicarum of Nelson (1963) are assigned toM. manitoba.2008040335贵 州 北 部 晚 奥 陶 世 四 射 珊 瑚 动 物 群 组 合 特征 、 古 生 物 地 理 亲 缘 关 系 及 群 体 灭 亡 = CombinationFeatures,paleobiogeographic affinityand mass extinction of the Latest Ordovician(Hirnantian)rugosan fauna from northernGuizhou,China.

Acta Geologica Sinica, 2007,81(1): 23-41The rugosan fauna from the Guanyinqiao Bed(latest Ordovician, Hirnantian) of northernGuizhou, China is known to belong to the coldor cool-water type corals. The components of thefauna are solitary corals only, and corallite septaare generally strongly dilated, especially thestreptelasmatid corals are dominant comprising98% of the whole fauna. The Guanyinqiao Bedis rich in rugosans of 18 genera, which are streptelasmatidStreptelasma (=Helicelasma),107
