Abstract:
The genus Shensiphyllum, as a special kind of fasciculate compound rugose corals, is characterized by one row horseshoe-shaped dissepiment and fan-like septal trabeculae. These features are unique among the known Silurian rugosan genera. This genus is widespread in the Upper Yangtze region Silurian, especially in the Ningqiang Formation (middle-upper Telychian)of southern Shaanxi and northern Sichuan, the Daluzhai Formation (middle-upper Telychian), northeastern Yunnan and the Shamao Formation, western Hubei. Three new species Shensiphyllum simplex sp. nov., S. proliferum sp. nov. and S. intermedium sp. nov. are described and illustrated in this paper, which are found from the Wangjiawan Formation (lower Telychian), Guangyuan, northern Sichuan, representing the first appearance horizon in the Yangtze region. In the present paper, the diagnostic features of Shensiphyllum, its growth gemmation manner and the skeletal structure features are discussed in detail, and it possibly originated from Stauriidae is inferred.Based on the present study, the diagnosis of Shensiphyllum needs to be modified and further supplemented, and its taxonomic position should be assigned to the family Phacellophyllidae Wedekind, 1922.

Abstract:
The latest Ordovician(Hirnantian) rugose coral fauna from the Guanyinqiao Beds in Bijie, Renhuai and Shiqian districts of northern Guizhou are studied in detail, and some genera and species are reviewed. 4 genera and 2 species of rugose corals are reported from the Guanyinqiao Beds in northern Guizhou for the first time, they are Axiphoria, Bodophyllum, Dalmanophyllum, Leolasma, Brachyelasma unicum (Neuman), and Grewingkia anguinea (Scheffen). In the past, quite a number of rugosan taxa, including the genera Borelasma, Kenophyllum and Ullernelasma, etc.had been discovered in the Guanyinqiao Beds (He, 1978, 1985). The present new material thus further enrich the content of the latest Ordovician (Hirnantian) rugosan fauna in the Upper Yangtze region and indicate the close affinities of the Late Ordovician rugosan faunas in the Yangtze region to those of Scandinavia and central Asia.Up to now, totally 39 species of 18 genera have been found from the Guanyinqiao Beds (see Table I). Among them, 12 species of 10 genera of rugosan are described in this paper, including 1 new genus and 3 new species, namely Amplexobrachyelasma He et Chen gen. nov., Grewingkia densicolumna He et Chen sp. nov., Kenophyllum fossulatum He et Chen sp. nov. and Leolasma qianbeiense He et Chen sp. nov.

Abstract:
Two new taxa ascribed to Scalaroxylon jalaidqiense Zhang et Zheng sp. nov. and S. multiforium (Zheng et Zhang) Zhang et Zheng comb. nov. were described in this paper from the Lower Triassic Laolongtou Formation of Defatun district, Jalaid Qi, Nei Mongol, China. The genus Scalaroxylon was found originally from the Upper Triassic (Keuper) of Franconia, Southern Germany. The new material documented represents the first record of this fossil wood genus in China. This genus is characterized by the secondary xylem with no growth rings. The pittings on radial walls of tracheids are of primitive scalariform type. The xylem rays are of a heterogeneous type. Both vertical and transverse ray cells are present. The horizontal and end walls of the ray cells have occasional pits, while their tangential walls are mostly pitted. This kind of special structure suggests that the genus Scalaroxylon differs from Bennettitales and primitive an- giosperms, but resembles some Late Paleozoic Pteridospermae (e. g. Medullosa) and living Cycadales (e. g. some species of Zamia). Thus, the Scalaroxylon may represent an intermediate form between the Pteridospermae and Cycadales.

Abstract:
云南虫类(yunnanozoans)是早寒武世澄江动物群中重要的原始脊椎动物,包括云南虫(Yunnanozoon)和海口虫(Haikouella)。由于保存原因,对云南虫的形态学了解十分有限。海口虫鳃弓保存了明显的鳃丝构造,而这个特征在云南虫中却没有报道。通过最近观察研究云南澄江小滥田5.3亿年前下寒武统帽天山页岩中采集的云南虫化石标本后,发现了类似海口虫的鳃丝构造,为该类动物的相互联系及脊椎动物起源和早期演化提供了新的化石根据。

Abstract:
新疆乌恰县西部斯木哈纳边境口岸北侧边境线附近含Zdimir腕足动物群的中厚层灰黑色生物碎屑灰岩一直被视为中泥盆统托格买提组。作为一个岩石地层单位,托格买提组的含义应该是分布在托格买提东一带及阿赖山东部以片岩、千枚岩、石英砂岩或以厚层灰岩为主、含腕足动物Stringocephalus,Bornhardtina和珊瑚Temnophyllum,Neospongophyllum等化石群的地层,主体时代为Givetian期。斯木哈纳边境口岸北侧边境线附近中厚层灰黑色生物碎屑灰岩与托格买提组的岩性差异较大,应另建新组名。对Zdimir动物群详细研究后证实,这套地层的时代大致为早泥盆世晚期(Emsian期)。

Abstract:
A new wasp, Eopelecinus yuanjiawaensis sp. nov., is described from the Lower Cretaceous Jiufotang Formation of the Yuanjiawa locality, Dapingfang, Chaoyang, western Liaoning and assigned to the family Pelecinidae (Insecta, Hymenoptera, Proctotrupoidea). Besides insects, many vertebrates including pterosaurs, dinosaurs and birds have been discovered from the same horizon in this area. Although comprising only three extant species confined to America, the Pelecinidae were widely distributed in Eurasia in the Cretaceous. In China, they have been found from the Yixian Formation in western Liaoning and Laiyang Formation in Shandong.

Abstract:
This paper reports the miospore assemblage of the lower part of the Yongzhu Formation, Xianza District, Northern Xizang (Tibet). The age of the lower part of the Yongzhu Formation is late Early Carboniferous (Visean) based on the ammonites, conodonts, corals and brachiopods. Abundant miospores and some acritarchs are found in the silty mudstone of the lower part of Yongzhu Formation. 43 genera and more than 70 species are recognized. The characteristics of the mio- spore assemblage are as follows:

Abstract:
以更新世全球性气候变化规律为基准,结合深海氧同位素阶段的划分,以及中国冰期与其对比关系等方面的研究进展,对以往学者所提出的一些更新世事件与氧同位素时段的对比关系进行了检验。结果佐证了南京直立人生活于昆仑主冰期,年代约为距今642ka—620ka,可能与MIS16相当的观点。研究同时表明:北京直立人可能生存于前大间冰期(MIS15—13)的初期,推测最早的北京直立人的年代为距今约620ka。

Abstract:
The Cretaceous biotas of Songliao Basin are divided in ascending order into the Jehol Biota in the faulted period, the Songhuajiang Biota in the depressed period and the Mingshui Biota in the atrophied period. The three major biotas are well developed and widely distributed. This paper summarizes systematically the main characters of each biota and reveals the general biota features, the general vertical distribution patterns and their significance on the research of biostratigraphy, ecological environment and paleoclimate.

Abstract:
Nowadays, as a conventional instrument, TEM has been widely used in investigation of ultra-microstructures of biological organs and tissues. Roughly started from the early sixties of the last century, TEM was applied to palaeontological studies, especially in palynology involving spores (megaspores in particular), pollen and acritarchs, etc. Through ultra-thin sectioning after preparation processes, the preserved microstructures of organic wall and its interior can be clearly observed. This is of significance in approaching the systematic classification and ontogenesis of relevant microfossils. In practice, from some Palaeozoic even Precambrian well preserved microfossils, valuable information has been obtained from ultra-microstructure study. However, such successive results need essential prerequisites, viz., some technical problems met in the preparation and ultra-thin sectioning of fossil samples should be correctly solved. The present paper introduces some experiential but effective methods in solving such problems, including the concentration of fossil specimens, the permeation of embedding resin into the specimens and several common problems in the sectioning process. Some actual examples of TEM's application in palynology are also provided.

Abstract:
A preliminary observation of some spore-pollen fossils has been made using Laser Scanning Confocal Microscope (LSCM). Some quite new features about the texture and ultrastructure of pollen have been detected for the first time, which opens up a new application of this advanced technique to microfossil study. After the successful observation of fossil pollen, the LSCM in the application of fossil study can be outlined as follows:1) The most pollen and autofluorescene fossils shine blue (488nm), yellow (568nm) or red lights (647nm) under the fluorescence microscope. According to the Fluorophore excitation/emission maxima spectrum, the argon ion will be the most effective one to excite the fossil samples. 2) To observe the internal structure of fossil pollen without destroying the specimens themselves. The LSCM could make a series of virtually optical sections with higher resolution than conventional light microscope. 3) To reconstruct the 3-D image after sequencing continuous optical sections to the fossils, which allows the researcher to view much detailed 3-D stretch and changes of certain structure in both internal and external views.
