中国南部水域膜孔苔虫属一新种：苔藓动物门：唇口目：膜孔苔虫科

连壁膜孔苔虫Ｍｅｍｂｒａｎｉｐｏｒａｃｏｎｊｕｎｃｔｉｖａｓｐ．ｎｏｖ．群体被覆、单层。相邻个以隆起的个虫墙缘为界,无室间沟。横壁孔室单孔型,由大、中、小三种单孔组成。侧壁孔室多孔型,由一列大孔和列小孔组成。新种个虫一般形态与大室孔苔虫Ｍｅｍｂｒａｎｉｐｏｒａｇｒａｎｄｉｃｅｌｌａ的单层群体相似,但其权成相邻个虫的界限和体壁孔室的结构及排列方式与大室膜孔苔虫有显著区别。

内蒙古西部额济纳旗晚奥陶世生物地理和奥陶-志留系分界

通过最近对内蒙古额济纳旗东南珠斯楞海尔罕一带(阿拉善地块)奥陶—志留系界线地层和生物群的野外调查和室内研究,首次在上奥陶统上部巴丹吉林组中发现阿什极尔中期(mid Ashgill)腕足动物化石巨大全嘴贝(Holorhymchus giganteus Kiaer),这是该属在我国奥陶系中的首次记录。根据未成年个体的切片所发现的腹壳顶端发育中隔板构造,修订该属定义,并证明研究小个体对识别物种特征、探讨个体发育和系统演化有重要意义。分析了全嘴贝属的群落生态、生物地理和演化意义后,发现它在奥陶纪末大灭绝过程中,因居群规模和分布范围极大地缩减,至今未发现其化石记录;但在志留纪初环境好转后继续存活,可暂视其为复活属。根据在拐子湖组近底部发现志留系最下部Akidograptus ascensus带的重要分子Normalograptus lubricus Chen et Lin,确定本区的奥陶—志留系分界。阿拉善地块因不发育Hirnantia动物群,表明奥陶纪末期它与扬子区、西藏、滇西等富含该动物群的地区属于不同的生物地理区系;在阿什极尔中期可能位于热带海域,与祁连山、中亚、乌拉尔等地有重要联系。文中描记H．giganteus种,评述正常笔石类(normalograptid)的系统分类位置并描记N．lubricus种。

Did hard substrate taxa diversify prior to the Great Ordovician Biodiversification Event?

The Great Ordovician Biodiversification Event (GOBE) refers to one of the greatest increases in biodiversity during the Phanerozoic. Recent studies have shown that this taxonomic increase can be attributed to elevated origination rates around the Dapingian–Darriwilian boundary in the Middle Ordovician, while extinction rates stayed relatively constant throughout the Ordovician. Even though this global pattern of origination and extinction appears similar across diverse groups and geographical areas, earlier studies suggested that hard substrate taxa may have diversified prior to the GOBE, during the Early Ordovician. Here, we quantify Ordovician diversification dynamics of hard substrate taxa while simultaneously accounting for temporally varying sampling probabilities. Diversification rates of hard substrate taxa, both as a whole and when analysed as separate groups, appear to be very similar to those of free-living benthic taxa. The observation that the diversification dynamics of many different taxonomic and ecological groups show the same temporal pattern, suggests a common cause of Ordovician diversification dynamics.

Middle–Late Ordovician brachiopods from Ningnan,southern Sichuan Province,Southwest China: Implications for macroevolution and palaeogeography

Middle to Late Ordovician brachiopods from the Huadan Formation (upper Darriwilian–Sandbian) of Ningnan County, southern Sichuan Province, are systematically documented here for the first time. The locality belongs to the western margin of the Upper Yangtze Platform, South China palaeoplate, and the brachiopod fauna includes one new genus and three new species as well as five other constituents: Hingganoleptaena sp., Acculina zhongliangziensis n. sp., Ningnanmena longisepta n. gen. n. sp., Kassinella (Trimurellina) minuta n. sp., Lepidorthis typicalis Wang, 1955, Protoskenidioides weixinensis Zhan and Jin, 2005, Porambonites transversus Xu, Rong and Liu, 1974, and Psilocamerella sp. Taxonomically it is a typical representative of a Middle to early Late Ordovician brachiopod fauna, and, together with some other evidence from other fossil groups like trilobites, conodonts, chitinozoans, a late Darriwilian–Sandbian age could be inferred for the horizon yielding this fauna. According to the richness of each constituent, this fauna is suggested to be called the Acculina-Ningnanmena fauna (ANF). Numerical palaeogeographical analysis shows that two broad palaeobiogeographic provinces could be recognized during this particular time interval, and, although the ANF is grouped into the South China cluster, it shares very little similarity with other representatives of that group except for two cosmopolitans. It further confirms that the Great Ordovician Biodiversification Event (GOBE), in other words the Ordovician radiation, was actually manifested by the strong localization of major marine organisms such as brachiopods, trilobites, graptolites, etc.
