    Abstract:
    Division of the Cambrian System into lower, middle and upper series was first suggested by Walcott(1891a,b) and has been followed by all subsequent workers. A stage classification has been proposed only for the Upper Cambrian of North America (Howell and others, 1944), based on the formational succession of the Minnesota Wisconsin region (Lochman Balk, 1971). Recently 4 new series and 6 new stages names for the Cambrian of Laurentia have been established by American and Canadian authors (Ludvigsen and Westrop, 1985; Palmer, 1998). The classical Middle and Upper Cambrian sequence for China is in Shandong, where is the type area for the establishment of the Middle and Upper Cambrian stages of China (Lu and Dong, 1952; Lu, 1962). Because the Lower Cambrian deposits in Shandong is incomplete,stage subdivisions have been proposed with those of eastern Yunnan in the Lower Cambrian (Lu, 1941,1962). In the first synthesis of North American and Chinese Cambrian biostratigraphy (Howell et al. ,1944; Lu, 1962), much of the present biostratigraphic framework on both sides of the Pacific was established. During the last 50 years, many publications concerning Cambrian trilobite faunas, biostratigraphic studies as well as ecological analysis of Cambrian trilobite distribution based on tectonic setting by both American and Chinese palaeontologists, have increased our knowledge and understanding of the Cambrian biostratigraphic correlation between North America and China (Chang and Jell, 1987; Jegorova et al., 1963;Kurtz, 1981; Lochman Balk and Wilson, 1958; Lochman Balk,1970,1974;Lu et al., 1974;Nogami, 1966; Palmer, 1965,1966,1971,1977,1981,1982;Palmer and Halley,1979;Palmer and Peel, 1979; Robison, 1976; Saito, 1933, 1934;Shergold and Nicoll, 1992;Shergold, 1993;Sundberg and McCollum, 1997). Based on these more recent palaeontological studies, it now seems possible to improve Cambrian correlation between China and North America made by different authors since 1937 (Endo, In Endo and Resser, 1937; Howell, 1947; Chang, 1957, 1986; Lu, 1962; Shergold, Laurie and Sun, 1990; Shergold, 1997; Peng, 1992).

    Abstract:
    The work on the definition of global Series and Stages of the Ordovician is now focusing on the selection of GSSPs for the base of Middle Ordovician Series. The Whiterock Narrows section in the Monitor Range was first recommended as the boundary stratotype for the base of the global Middle Ordovician Series with the boundary placed at the first appearance of T. laevis. However, the age for the boundary level at this section is younger than expected previously and is correlated with the Yapeenian to the lowest Darriwillian, but not with the Isograptus victoria lunatus Zone. Albanesi and Ortega (2001) proposed the Niqivil section, Argentina as the global stratotype for the base of the Middle Ordovician with the FAD of Protoprioniodus aranda or of simultaneous Texania heligma as alternative index species for the boundary biomark. However, our recent research demonstrates the first appearance of this species in the middle of Upper O. evae Biozone at the Wengxigou section of Chengkou, indicating the FAD of P. aranda there is slightly lower than that reported in Argentina.

    Abstract:
    The Dongrong Formation previously considered Late Jurassic in age, distributed in the Suibin area of northeastern Heilongjiang Province of NE China, is a unit of continuous shallow marine clastic sediments with a maximum thickness of about 395 m. It may be divided into two parts, the lower part consisting of dark grey and black siltstones intercalated with some tuffbeds, and the upper part composing of grey and dark green fine grained sandstones intercalated with tuffs. Sun Xue kun and He Cheng quan(1992)reported abundant marine dinoflagellate fossils from both parts of the formation. A rich and diverse dinoflagellate cyst assemblage dealt with in this work is obtained from the uppermost part of the Dongrong Formation of seven boreholes in the area. It is composed of at least 19 genera and 30 species with 1 variety of dinocysts, 1 genus 1 species of acritarchs, of which 21 species with 1 variety of dinoflagellates are described and illustrated, including one new species,Leberidocysta suibinensis sp.nov.

    Abstract:
    In the fifties of last century Mr. Su De Zao (former Su Te Tsao) of the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, first described three genera and species of fishes from the Keichousaurus bearing horizon in Xingyi of Guizhou, they are Peltopleurus orientalis Su, 1959, Sinoeugnathus kueichowensis Su, 1959, and Asialepidotus shingyiensis Su, 1959. The then five incomplete fish fossils were collected in 1957 by Mr. Cao Zhe Tian of the Guizhou Museum at Langmu, Dazhai village, Tingxiao of Xingyi. Later on, nobody had made futher investigations and studies for more than two decades. It is an interesting comment in the eighties of last century that the search for fantastic stones let to the discovery of abundant and diversified fish fossils from the Keichousaurus bearing horizon in Xingyi of Guizhou. It is very fortunate that we collected some complete and beautiful specimens of fish fossils from a lot of collectors and dealers in fantastic stone. Moreover, in 2001 and in 2002 we went Xingyi to do field exploring and confirmed that they occur really in the Keichousaurus bearing horizon. One among them, that was used as the holotype of a new genus and species of the family Amiidae, had been described initially in 2002 by the first three authors of this paper, and some supplementary descriptions and necessary discussions will be made in this paper. These new discoveries of great importance have helped us more understanding of the fishes from the Keichousaurus bearing horizon, and moreover, the characters of a distinctive fish fauna of the Late Triassic in Xingyi of Guizhou also have appeared more enough. The new forms and new material of Guizhouamia from the Keichousaurus bearing horizon are deseribed as follows.

    Abstract:
    Restudy of Grabau's type specimens shows that Sinospirifer Grabau, 1931 differs from Cyrtospirifer Nalivkin, 1924 in a number of important shell characters. Sinospirifer is distinguished from Cyrtospirifer by its secondarily infilled ventral posterior, a pseudodeltidium penetrated by a central pedicle tube/foramen, and the whitneyi-subextensus micro-ornament. The type species Spirifer (Sinospirifer) sinensis (subsequent designation by Tien, 1938) is a junior synonym of Spirifer verneuili var. subextensus Martelli, 1902, and henceforth Spirifer subextensus is the type species of Sinospirifer. Most of the illustrated type specimens of eight species of Sinospirifer named by Grabau (1931) are closely similar to Sinospirifer subextensus (Martelli, 1902) in their overall shell shapes, sinal plication patterns, and the presence of a central pedicle tube/foramen, as well as the whitneyi-subextensus micro-ornament, and are considered to be conspecific with S. subextensus. These include Sinospirifer sinensis, S. archiaciformis, S. wangleighi, S. pellizzarii, S. pellizzariformis, and S. heterosinosus. A number of specimens of Sinospirifer vilis and S. subhayasakai illustrated by Grabau (1931), including their holotypes, are transferred to S. subextensus, and the remaining specimens are attributed to four or five other species.

    Abstract:
    Very abundant and well preserved megalodontids have been found in the Jiapila Formation of the Upper Triassic from the area about 7km west of Quemocuo Lake, north slope of the Tanggula Mountains, Qinghai Province(Text fig.1). The Jiapila Formation disconformably overlies the Upper Permian Lapuchari Formation, and includes two members, the Upper and Lower members. The Lower Member consists of lime conglomerate, tuff, and pebbled tuff, intercalated with coarse grained quartzose sandstone, and pebbled coarse grained sandstone, 576m in thickness. No fossil has been found in the Lower Member yet. The Upper Member is made up of micrite, 97 160m thick, and yields 3 beds of megalodontids fossils (Text fig. 2). The large sized megalodontids (more than 80mm in height) occur in the lower part, while the small ones (less than 20mm in height) in the top. Those deposits indicate the shallow water,high energy and protected back barrier carbonate platform setting. The sedimentary environment of megalodont bearing rocks in northern Tibet is very similar to the Yaritaoshi limestone of Kyushu and the Hanagato limestone of Shikoku in the Sambosan belt of the southwest Japan. The megalodontids in studying area have very lower diversity in the levels of both genus and species. Except for a few specimens of Palaeocardita , megalodontids are associated with gastropods and algae. The new taxa of large sized megalodontids including Quemocuomegalodon Yao, Sba et Zhang (gen. nov.), Q. orientus Yao , Sba et Zhang (gen. et sp. nov.), and Q. longitatus Yao, Sba et Zhang (gen. et sp. nov.) are described in the present paper.

    Abstract:
    Palynological study of the Carboniferous Permian coal bearing strata in China has contributed quite a wealth of publications since the sixties of the last century. Most of them, however, served the purposes of stratigraphical dating and correlation as well as of basic research such as the description of many taxa, etc.,only a few papers were specifically dealing with spores and pollen from coals (Imgrund, 1960; Liao, 1987a,b; Yao and Lu, 1992; Tang, 1997). No attempt to discuss the mire flora or coal forming plants and their ecology has been made so far.

    Abstract:
    Here we report the finding of eggs in 2 cell, 4 cell, 8 cell and 16 cell cleavage stages from Precambrian Doushantuo Formation, Weng'an, central Guizhou (Southern China). These eggs bearing a number of shared features suggest that they were derived from early animal belonging to the same species. These features include:same size; egg shell ornamented with identical structure; presence of perivitelline space; and equally holoblastic cleavage with spherical early cleavage cells. The identical eggs have been described as animal resting eggs by some authors and the presence of different cleavage stages indicates that they were developing eggs. Therefore, the resemblance with the resting eggs of some modern crustaceous forms in egg shell ornamentation can not be taken as a sign for their affinity. The perivitelline space mainly occurs in the eggs of modern bilaterians. The occurrence of the perivitelline space from 580 million years old eggs indicates that bilaterians might have evolved in a deeper time before Cambrian explosion.

    Abstract:
    We studied the phylogenetic relationships of 29 genera of 21 families using 18SrDNA partial sequences. Maximum parsimony (MP), maximum likelihood (ML) and neighbor joining (NJ) analyses combined with fossil records and morphological characters of Ostracoda were used to discuss the phylogenetic relationships among different lineages of ostracodes. Our results show that Podocopida, Myodocopida, superfamily Cypridinacea are monophyletic in all trees, whereas superfamily Bairdiacea is not. The monophyly of Myodocopida and Podocopida are strongly supported by molecular data. Our study also suggests that evolutionary radiation possibly occurred many times at different taxonomic levels of Ostracoda in history.

    Abstract:
    Abundant mammalian fossils of Neogene fauna are widely spread in eolian dust accumulation in northern China. In field buried skeletons are overlapped, fossils saved in a panticular state. Taphonomic process and deposition environment of fossiliferous layers are problems that paleontologists hope to solve. The discovery of new mammalian fossils in Renjiapo, Lingtai, Gansu throws some light on those doubts. Most skeletons of Renjiapo Pliocene mammalian fauna are saved organically isolated,a few connected materials are skulls and Alta vertebrae,and the ends of limb bones, etc. Weathering traces on the skeleton surface are diverse. A lot of gnaw marks of rodents are on bones. The damages of fossil materials are about 30 percent of whole ones. Rupture of the bones is stepping one. Orientation of long axes of elongate bones in the fossiliferous layer has obvious direction. There are some similarities in taphonomic features between the Renjiapo Pliocene mammalian fauna and the flood plain fauna. The general features are: fossils are abundant and concentratedly distributed. They include parts of individual bodies and different taxa. Joint and scattered bones, complete and broken bones exist in same area. Acting marks of other animals are general, age distribution of population indicate attrition mortality. The actions of water transportation and sorting existed. However, there are also different features. For example, the grain size of flood plain deposits is relatively coarse. They usually contain some sands. Fossils are distributed successively. These general and specific characters may be considered as the similarity of taphonomic process and variance of taphonomic environment. The taphonomic character of Renjiapo Pliocene mammalian fauna is similar to that in North China. Distinguishable features may be caused by different transportation course, transportation distance and transporting agent. Therefore, taphonomic knowledge of Renjiapo Hipparion fauna affords some references to understand the taphonomic processes of Hipparion fauna in China.

    Abstract:
    Yuan and Yin (2001) transferred Protaitzehoia from the family Damesellidae to the family Ordosiidae. Based on study of the new material from the Huaqiao Formation of western Hunan, and on examination of the type material of existing species, we conclude that the transfer made by Yuan and Yin is incorrect, and that the genus belongs certainly to the Damesellidae. Three new species (subspecies) erected by Yuan and Yin (2001), namely Protaitzehoia quadrata jimachongensis Yuan and Yin, Protaitzehoia nitida Yuan and Yin, and Protaitzehoia latilimbata Yuan and Yin, are from the same locality at Jimachong, Yuping, eastern Guizhou with the type material of Protaitzehoia granifera Yang , 1978. They are all proved to be junior synonyms of the latter species. In addition, two species from Wa'ergang, Taoyuan, northwestern Hunan, namely Protaitzehoia intermedia Peng, 1987, and Protaitzehoia sp. ( sensu Peng, 1978), are respectively junior synonyms of Protaitzehoia subquadrata Peng, 1987, and Protaitzehoia granifera Yang, 1978. Currently, Protaitzehoia includes only five species, i.e. Protaitzehoia yuepingensis Yang, 1978, the type species; P. granifera Yang, 1978; P. subquadrata Peng, 1987; P. quadrata (Resser and Endo,1937); and P. sp. sensu Peng, Babcock, and Lin, 2001.
