    Abstract:
    文内记述了山东长清张夏徐庄阶三叶虫,计有13属16种,其中1新亚属及5新种;划分为4个三叶虫化石带(自上而下):Bailiella-Lioparia带、Poriagraulos nanum带、Sunaspis laevis带和Hsuchuangia-Ruichengella带,并与辽东地区、山西中条山和河南中-西部徐庄阶三叶虫化石带作了对比。由于此地是徐庄阶命名所在地,故其三叶虫化石带可做为对比的标准。

    Abstract:
    Subdivision of the classic Lower Cambrian stratigraphy of Chengjiang County, eastern Yunnan, China, is revised in light of recent discoveries and interpretations of the regional stratigraphy, and recent interpretations of biotic changes across the Precambrian Cambrian boundary. Modification to lithostratigraphic nomenclature, chronostratigraphic zonation, and biostratigraphic zonation of Lower Cambrian units are summarized. As presently recognized, lithostratigraphic units are, in ascending order, the Yuhucun Formation (Meishucun Stage), the Heilinpu Formation (Qiongzhusian Stage), the Hongjingshao and Wulongqing formations (Canglangpuian Stage) and the Shanyicun Formation (Longwangmiaoan Stage). Biostratigraphically, this succession is divided into 12 assemblage zones and two subzones. All of the assemblage zones are recognizable throughout the Southwest China Platform, but the subzones are of local utility. The position of the Sinian (Neoproterozoic) Cambrian boundary in eastern Yunnan is tentatively placed at the base of the Xiaowaitoushan Member of the Yuhucun Formation, just below the first appearance of small shelly fossils. Chinese Parabadiella, Moroccan Abadiella and Australian Abadiella huoi are reviewed. We prefer to maintain Parabadiella and Abadiella as separate genera. Type specimens of these two genera are reillustrated. Australian Abadiella huoi is a new species of Wutingaspis jelli Chang sp. nov. and pik's (1975) Dolerolenus (?) sp nov. is a species referred to Parabadiella huoi Chang (1966). Parabadiella huoi is the oldest Cambrian trilobite not only in China but also in Australia. The stratigraphic position of Wutingaspis jelli in Australia and Abadiella in Morocco is equivalent to the upper part of the Wutingaspis Eoredlichia Zone in China.

    Abstract:
    根据对苏北新元古代九顶山组似锥叠层石标本的分析,初步揭示构成似Conophyton叠层珠微生物席可以分为两类。这两类席被作者称为“开端微生物席(first microbial mat)”和“继承微生物席(succedent microbial mat)”。它们在整个叠层石发生和发育过程中起作不同作用。Conophyton叠层石的形态发生可能与开端微生物席的造型有着密切联系,这类微生物席在叠层石形态过程中起作生长“芽”或模具作用。继承微生物席仅仅起作叠层石的增高或增大的作用,它的发育经常受环境制约。

    Abstract:
    Trilobites described in this paper were collected from the uppermost Torsuqtagh Group in Southern Yaerdang Mountains and Queerqueke Mountains, south of the Kuruktag area, Xinjiang by the 1st Regional Geological Surveying Team of Xinjiang in 1981 and by Lin Huan-ling and others of Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences in 1993. They consist of 9 species and 3 indetermined species, belonging to 10 genera and 2 subgenera. The uppermost Torsuqtagh Group can be subdivided into two trilobite zones: the lower part (corresponding to the conodont C.lindstroemi Zone) is assigned to the Hysterolenus Zone, and the upper part (equivalent to conodont C. angulatus Zone) Dichelepyge sinensis Zone. The former includes Hysterolenus oblongus Lisogor, Borthaspidella anderssoni (Troedsson), Niobe (Niobella) preciosa Lu et Z.Y.Zhou, Leiagnostus sanduensis Zhou, Proteuloma sp., Euloma sp., Dividuagnostus cf. longa (Ju) and Symphysurus (Troedssonia) sp. The latter comprises Dichelepyge sinensis Lu et Lin, Bienvillia cf. tetragonalis (Harrington), Prospectarix exquisita Zhou et al., Lotagnostus (s.1.) orientalis (Lu et Lin). Based on conodonts, the Cambrian-Ordovician boundary in the southern Kuruktag area may be fall within the Hysterolenus Zone.

    Abstract:
    Based on well preserved cranidia and pygidia from the Chefu Formation(early Late Cambrian) of Jimachong, Wanshan District, eastern Guizhou, South China, the genus Protaitzehoia Yang, 1978 is here revised and transferred from Damesellidae to Ordosiidae. 2 new species and 1 new subspecies are established, namely: Protaitzehoia latelimbata sp. nov., Protaitzehoia nitida sp. nov., and Protaitzehoia quadrata jimachongensis subsp. nov.

    [Abstract](340) [HTML](0) [PDF 0.00 Byte](4)
    Abstract:
    Taoqupognathus is a multimembrate panderodontid conodont, consisting of distinctive, blade-like, coniform elements with various degrees of posterior bulging. The genus is restricted in distribution to the Upper Ordovician of eastern Australia and China, where the four known species are useful for precise regional correlation. A cladistic analysis of morphological characters indicates that the mian evolutionary trend of Taoqupognathus appears to follow the lineage: T.philipi-T.blandus, and T.tumidus during the Eastonian (middle Late Ordovician), with T.philipi as the most primitive form. The distribution of Taoqupognathus suggests a close biogeographical link between eastern Australia and China with the genus apparently originating in central New South Wales in the early Eastonian. It then migrated to Chinese crustal blocks during the summit of its development in the mid-late Eastonian, and probably became extinct in the latest Eastonian or early Bolindian.

    Abstract:
    研究材料系自浙江江山晚奥陶世黄泥岗组硅质结核中的Telephina convexa Lu眼部内模和外模标本。使用SEM二次电子图像把眼部放大,发现其小眼体是透镜体,外形为正八角形的透镜体,正八角形的每一相间的部位为正方形的眼间体(interlens)所占据,它们填充在八角形小眼体顶角和底角外侧的空间。每一正八角形的边长为66.66μm,小眼体之间为四向两组垂直交叉排列。Telephina的眼是介于在叶虫复眼和聚合眼之间的一种特殊类型的眼。从眼的构造和形态来看,Telephina 应属于中远洋悬浮类三叶虫,与Cyclopyge近似。

    Abstract:
    Yuan and Yin (2000) classified Prodamesella into 3 subgenera, and transferred the genus from family Damesellidae to family Missisquoiidae. Study on the material of ontogenetic series of Prodamesella punctata Ergaliev from western Hunan, with discovery of its reliable pygidia, reveals that the classification and the familial assignment made by them may be problematic. The new material shows that the cranidia, on which Yuan and Yin based for their new taxa are mainly of juvenile, and the pygidia appear to belong to other genera rather than Prodamesella. The subgenera Prodamesella (Metaprodamesella) Yuan et Yin and Prodamesella (Neoprodamesella) Yuan et Yin are considered to be invalid, and species (subspecies) P. subtriangulata Peng; P. (Prodamesella) cylindrica Yuan et Yin; P. (Metaprodamesella) subtriangulata prisca Yuan et Yin, P. (Metaprodamesella) granulosa Yuan et Yin;Prodamesella (Neoprodamesella) spinosa Yuan et Yin are junior synonyms of P. punctata. All the generic characters of Prodamesella suggest that the genus can be assigned neither to the family Damesellidae nor to Missisquoiidae. Because there appears no existing family, in which the genus could be satisfactorily placed, we prefer to remain it uncertain in familial rank.galiev from western Hunan, with discovery of its reliable pygidia, reveals that the classification and the familial assignment made by them may be problematic.
