Abstract:
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。

Abstract:
During last three decades, the Wargal and Chhidru Formations in the Salt Range, Pakistan and their equivalents in the Himalayan region have been considered by many authors to be Middle Permian (Guadalupian) in age. Based on the correlation of the Guadalupian and Lopingian conodont zones of the Salt Range, Pakistan with those of South China, the Amb Formation and the lower part of the Wargal Formation in the Salt Range, Pakistan are Late Guadalupian in age. The Guadalupian/Lopingian boundary is in the lower part of the Wargal Formation, and the Wuchiapingian/Changhsingian boundary is in the lower part of the Chhidru Formation. The Permian/Triassic boundary is in the Kathwai Member of the Mianwali Formation. Thus, it can be inferred that the Selong Group in the southern Tibet is also Lopingian in age in view of its correlatable brachiopod faunas with those of the Kalabagh Member of the upper Wargal Formation and the Chhidru Formation and the conodont zones around the Permian/Triassic boundary in southern Tibet.

Abstract:
genera of rugose corals are reported from the middle Llandovery in northern Guizhou Province of China for the first time. They are Cantrillia,Neocantrillia,Prototryplasma,Pycnostylus,Dalmanophyllum?, Rhegmaphyllum and Schlotheimophyllum. In addition, two species(Grewingkia cf. bilateralis(Neuman) and Brachyelasma cf. medioseptatum(Neuman) ) collected from the late Ashgill Guanyinqiao Beds in the Shiqian County of northern Guizhou Province, and one species(Crassilasma sp.)from the early Ashgill Jiancaogou (Jiantsaohou) Formation in the same area are described. These data enrich further the content of the Late Ordovician and Early Silurian rugose coral fauna in Yangtze region, and are considerably significant for study on origin, evolution and disperse of some Early Paleozoic rugose corals. Altogether 18 species assigned to 13 genera are described. Among them 6 species are new. They are Crassilasma fenggangense sp. nov., C. crebrumseptatum sp. nov., Dinophyllum insolitum sp. nov., Neocantrillia silurica sp. nov., Prototryplasma guizhouense sp. nov., and Schlotheimophyllum regeneranum sp. nov.

5 MICROBIALLY MEDIATED PHOSPHATIZATION IN THE LATE SINIAN SKELETAL FOSSILS, SOUTHERN SHAANXI

Abstract:
SEM observation of the earliest skeletal fossils from the late Sinian Dengying Formation in southern Shaanxi, China indicates that the tube wall of Sinotubulites levis is encrusted by phosphate spherical and filamentous structure, possibly reflecting microbially mediated phosphatization of tube wall. Three preservational microfabrics detected, namely mat-like structure formed by intertwining of rigid filaments, densely packed spheres with a distinctive framboidal external surface and hollow centers and tightly packed spherical bodies with extremely smooth external surface, may refer to different types of mineralized cyanopytes. The rarely occurrence and totally absence of phosphatized microbes on the walls of the co-occurred S. baimatuoensis and Cloudina respectively imply that phosphatization of microbes was taxon-specific, and may due to the discrepancy of wall structures. The multi-walled S. levis with smooth outermost surface may be closely related to polychaete tubes with many organic laminae.

Abstract:
In 1992 Xue et al. reported some skeletal fossils, including one genus and two species, from the Neoprotorozoic Doushantuo Formation at Weng'an, Guizhou, and assigned them to Echinodermata. In this paper, new materials of phosphatized cylindrical and tabulate microfossils, including a new genus and two new species, are described from the same layer and locality. It provides us much more evidence not only to display the Neoproterozoic biodiversity, but also to explore the origin and the early evolution of biomineralization.

Abstract:
A new fossil plant, Alloephedra xingxuei gen. et sp. nov. is described. The fossils were collected from the Dalazi Formation in Yanji Basin, Jilin Province of China. The Dalazi Formation belongs to the Aptian-Albian of Early Cretaceous in age. Impressions of reproductive shoots, female cones and seeds were preserved in a fossil specimen and its counterpart. The new fossil plant is comparable to the living Ephedra on account of a series of morphological characters, including the striated shoots and branches, the bi-ovulate cones, the seed with a short micropylar tube, and is attributed to Ephedraceae thereby. Comparisons between the new fossil and other known ephedroid fossils and extant Ephedraceae are performed. The occurrence of Ephedraceae in Dalazi Formation is a significant paleoclimatological and paleofloristic indicator for the locality.

Abstract:
对东海陆架西南部台北坳陷13口钻井孢粉分析表明，本地区新近纪植物群经历了3个发展阶段，即：1)早中新世早期松科花粉优势期；2)早、中中新世阿丁枫科花粉繁盛期；3)晚中新世至早上新世草本被子植物发展期。各时期孢粉植物群在横向上几乎没有大的区别，表明新近纪整个坳陷内构造与沉积环境及其变迁具有很好的一致性。植物群演替反映古气候从早中新世早期的湿润温凉到早、中中新世的暖湿，最后(晚中新世至早上新世)又趋温凉的变化历程。

Abstract:
通过对青藏高原东部兴措湖腹足类Gyraulus sibirica壳体同位素的分析，并与器测气象资料的相关研究，建立兴措湖同位素记录与对应的降水和气温间的函数关系。对区内200年来的温度序列进行定量恢复，结果表明，青藏高原东部兴措湖地区腹足类生物壳体主要在温季生长，它所记录的是温季而不是全年的气候环境信息；Gyraulus sibirica壳体δ^18O指标与温季滑动平均温度明显为正相关系，相关系数为0．89；δ^13C指标与温季的降水量呈正相关系，相关系数0．71；近200年来研究区温度变化有3个明显的阶段，其中20世纪初的低温期温度比目前平均低3.7℃。

18 NEW ASSESSMENT OF THE FOSSIL RECORDS

2003(2):297-302. DOI: 1

[Abstract](390) [HTML](0) [PDF 0.00 Byte](7)

Abstract:
For a long time, fossil record is used as a literal source of data on the history of the diversification of life and of mass extinctions without applying any correction factors for possible time-related bias. Its status has recently been questioned by molecular-clock based studies and cladistics. Molecular clocks have an advantage over fossil clocks in counting mutations at the actual time of divergence. Cladistics is based on character information intrinsic to the taxa while the stratigraphy on the fossil sequence extrinsic to those taxa. However, even those two methods have their own disadvantages. Fortunately, the ideal continuous fossil records do exist, and are invaluable for unravelling the paths of evolution. The fossil record is usually in complete for all groups at all times and in all places. Whatever the quality of the fossil record it must contain information about time of a species' genesis and extinction. We should not ignore this information but rather find ways to use it properly. The database could provide a general concept for the studied subject with the previous results being reviewed systematically. The statistic analyses, including the confidence and likelihood approaches, have been proved useful in assessing the incompleteness of the fossil record. These two methods open a new window for the development of stratigraphy.
