Abstract:
All described Permian Triassic reefal thalamid sponges are checked under the same taxonomic standard of species and those incorrectly assigned are placed respectively in the right taxon. Then the thalamid sponges of different Permian Triassic periods are compared at specific level in this study. The division of Permian System by Jin et al. (1997) (Table 1) and that of Triassic System by Harland et al . (1989) (Table 2) are followed. All described thalamid sponges from Permian and Triassic reefs are included in the study, except for those without pictures, which makes it impossible for us to check their identification. Pictures of all described thalamid sponges used in the study have been compared to the picture of the monotype of a given species and those inappropriately identified by previous researchers were assigned to the right taxon. In previous studies medium size (diameter > 0.5 cm) and large size (diameter >1 cm) thalamid sponges caught more attention. On the contrary, small thalamid sponges were mostly overlooked. In this study small thalamid sponges in the Changhsingian reefs of Ziyun, Guizhou Province, China are also included.

Abstract:
This paper describes the Sanhe flora found at Qingshui stream near the town Sanhe in Longjing County, Jilin Province, Northeast China. This flora comprises 24 species belonging to 22 genera within 17 families and represents a mixed coniferous and deciduous broad leaved forest. Here, only 17 known species, one new species, Zizyphus orbitofolia and 6 undetermined species are described. This flora has a great diversity of species. In addition, comparison is made among the Sanhe flora and the Hoeng yeong and the Kogeonwoon floras in North Korea. As a result, the fossil bearing strata, as a new stratigraphic unit the Sanhe Formation is suggested. Based upon comparison with other Asian Tertiary floras, the Sanhe flora is considered to be Oligocene in age.

Abstract:
晚奥陶世的冈瓦纳大陆冰川导致全球性海退和两幕生物灭绝事件，第一幕，也是高潮幕，发生于Rawtheyan期末；第二幕发生于Hirnantian期末。在经历第一幕事件的过程中，扬子地台西缘的四川汉源地区大渡河组浅水相灰岩和硅质灰岩中出现了极其繁盛的底栖藻类，局部层位中可达到造礁的程度。大量底栖藻通过光合作用改善、缓冲了这一浅海地区的低温、缺氧的灾变环境，并成为生态系统重建的先驱群落。局部浅海环境的正常化为后生动物腕足类、三叶虫和海百合在Hirnantian期南郑组的短暂复苏创造了生存条件。当后生动物再度成为生态系统的主体时，啃食压力的增大使底栖藻的居群数量骤然减低。始于Hirnantian后期冰川消融的海进造成第二幕Hirnantia动物群的灭绝。

描述陕南南郑梁山中奥陶世Llanvin早期7种三叶虫，包括两个新种Bathycheilus sinensis sp.nov.和Pseudocalymene sculpta sp.nov.,其中Bathycheilus一属在我国系首次发现。三叶虫组成和埋葬相特征表明这一动物群的底栖分子应生活于水体安静，深度大于风暴浪基面的灰泥质海底环境。这些底栖三叶虫属于环冈瓦纳动物群的一个组成部分，但显示了与北欧动物群的一定联系。

对采获于我国内蒙古二连浩特晚白垩世达布苏组的蜥臀目兽脚亚目似鸟龙科恐龙（Archaeornithomimius asiatcus)和鸟臀目鸟脚亚目鸭嘴龙科恐龙（Bactrosaurus johnsoni)的胫骨、排骨、股骨、尺骨、肋骨、椎骨骨组织结构特征进行了研究，并将它们的骨组织与爬行纲初龙亚钢的现存湾鳄（Crocodylus porosus)和非洲Tuo鸟（Struthio camelus)的骨组织进行直观比较，应用计算机图像分析技术及统计方法进行比较研究。结果显示：1）这两种恐龙的骨组织具有相似的基本结构特征，但也存在一些差异；2）两种恐龙的长骨组织均具有快速后生生长特点；3）似鸟龙科恐龙的幼年长骨只速率高，成体则相对减慢；4）似鸟龙科恐龙的幼体肋骨中具有生长轮，成体的肋骨中则生长轮有可能因骨改建而消失；5）两种恐龙、非洲Tuo鸟和湾鳄的长骨的血管分布密度有统计学的显著差异，两种恐龙的骨组织血管密度介于非洲Tuo鸟和湾鳄之间；6）这两种恐龙的骨组织既不同于现代鸟类骨组织，也不同于现代爬行类骨组织，有可能是介于这两种骨组织之间的一种独立的过渡类型或中间类型。

Abstract:
Microfossils from Paleogene lacustrine oil source rocks of the Pearl River Mouth Basin, Beibuwan Basin and Bohai Gulf Basin have been studied. The Paleogene lacustrine microfossils of Bohai Gulf Basin are characterized by their high abundances, high diversities, high proportion of local species as well as saline species and the occurrence of talassogenous fauna. In Beibuwan Basin, only ostracods,gastropods and charophytes are discovered in the Weizhou Formation and Liushagang Formation; microfossils are rare in the Paleogene lacustrine sediments and only shell debris were found in some samples. According to the characteristics of microfossils of the three basins, we speculated that the Bohai Gulf Basin was a hydrologically closed lake during Paleogene and in some periods it was a saline lake rich in Na and Cl. The Paleogene lacustrine oil source rocks of Pear River Mouth Basin were deposited in a freshwater lake with lower salinity, hardness and pH. The Paleogene lake of Beibuwan Basin was a freshwater lake too, but with higher salinity.

Abstract:
The diatoms lound from the Holocene sediments of 2 well's cores in Putian and Quanzhou areas of the East China Sea have been systimatically researched, and 117 species and varities in 33 genus identified. 7 diatom zones have been divided according to the characteristics of the diatom assemblages and computerised corresponding analyses,and 7 stages of paleoenvironmental evolvement are reconstructed.The results supply the gap of systimatical study of diatoms in sediments of the areas and enrich the study of diatoms in sediments of the continent marine margin.

[Abstract](259) [HTML](0) [PDF 0.00 Byte](5)

Abstract:
Abundant rugose corals including 33 genera and 77 species were collected in 1988 from the fusulinid Montiparus zone to Brevaxina dyhrenfurthi subzone in South Guizhou. Among these species, 10 species are here described as new. Based on stratigraphical distribution of these rugose corals, 4 assemblage zones can be recognized as follows in ascending order: 1) Antheria Pseudotimania Assemblage 2) Nephelophyllum Eokepingophyllum Assemblage 3) Parawentzellophyllum Kepingophyllum Assemblage 4) Anfractophyllum Assemblage 1) and 2) assemblages are dominated by Cyathopsidae taxa Pseudozaphrentoides, Botherophyllum and Caninophyllum as well as primitive representatives of Kepingophyllidae. It is noteworthy that some pioneers of Waagenophyllidae and Wentzellophyllidae have occurred in the Assemblage 2). Assemblage 3) is represented by typical elements of Kepingophyllidae, including Kepingophyllum, Parawen tzellophyllum , and Diversiphyllum. Taxa belonging to Cyathopsidae and those primitive representatives of Kepingophyllidae are significanlly decreased in number in this assemblage. Assemblage 4) is dominated by such advanced representatives of Kepingophyllidae as Anfractophyllum and Szechuanophyllum.

Abstract:
The origin of life is one of the greatest scientific enigmas in modern world, and has ever attracted public attention. The elongated and complicated chemical process before the earliest cellular organism is defined as the chemical evolution of life. The chemical evolution of life and the early evolution of the earth's lifeless components constituted a set of interrelated, interactive and restricted processes. We illustrate the complicated series of chemical reaction, the formation of small organic molecules from inorganic matter, and then that of large organic molecules, and finally the origin of the earliest primitive cells in respect of the environmental evolution of the Universe, the Solar system and the primitive Earth. We also discuss and summarize most popular current hypothesis about the chemical evolution of life, concerning its early chemical evolution in primitive oceans, on the surfaces of clay minerals, via eruption of volcanoes, or came from the outer space beyond the Earth.
