The Chenjiawo fauna includes two stratigraphically distinct groups of mammalian fossils, 14 species of mammals and 4 stratigraphic horizons. They are L5, L6, S6 and L8-S9, representing a wide temporal distribution. The first appearance of Peking Man fauna can be correlated with Event 9 in America and Europe (Repenning, 1987) and is marked by the lowest stratigraphic occurrence of Cricetinus varians (LSD ). In northern Europe, Event 9 is believed to have taken place near the end of the Saale glaciation about 500 000 years ago (Bonifay, 1990). Therefore the geological age of the Chenjiawo fauna is between 500 000-1000 000 years B. P., corresponding to oxygen isotope. Stages 14-2.. Through the correlation between the solid earth, atmosphere,hydrosphere, and biosphere, the boundary between the Upper and Lower Lishi Formation should be moved to the S4/L5 boundary.

Totally 19 samples of typical Upper Proterozoic Lower Cambrian sedimentary rocks were collected and analyzed for an organic geochemical investigation. Almost all these rocks have high TOCs, super maturities and similar biomarker distribution. As an exception, however, the Sinian Nantuo Tillite shows much lower TOCs and little phytane and pristane in comparison with those in other strata, which implies a very faint photosynthetic process, and a restricted euphotic zone and quite limited sunlight within the sedimentary water column during the Sinian glaciation age in the western Yangtze region providing an evidence for palaeo oceanic environment of the Neoproterozoic Snowball Earth age.

Track fading is a basic phenomenon in track science and has been the source of informa- tion in geosciences. This article summarizes the knowledge of track fading and gives some examples of successful applications of track fading in archaeology, tectonics and geothermal chronology in china. The applications of track fading are classified into 5 modes：（1） mode of complete fading （annealing）; （2. mode of partial fading; （3） use of the dependence of track fading on time and temperature; （4） use of the differences of track fading between coexisting minerals; and （5） use of fading-reduced track length. Track fading mechanisms hints that scientists in geothermal chronology should adopt microprobes for quantitative elemental analysis to determine the detailed chemical compositions of each mineral grain or at least of the grains from each position of geological structures in order that one becomes well aware of the relation between the track fading behavior and chemical compositions of the mineral used.

Zebrafish is a good vertebrate model for development studies. Research on gene expression and regulation during zebrafish embryonic development plays an important role in revealing the molecular mechanism of morphogenesis in vertebrate. Tubulin locates the cytoplasmic determinants in eggs, organizes the formation of basic cytoskeleton and controls various cell movements. There are several types of tubulin, each of which has specific expression regions and functions. In this study, the full_length cDNA of a Xenopus β 2.tubulin was used as template to generate Dig_labeled antisense RNA which was used as a probe to carry out in situ hybridization on whole mount zebrafish embryos. Under the experimental conditions, the tubulin transcript was first detected in a group of cells in embryos at the midblastula stage. With the development of the embryo, this transcript was gradually restricted to the nervous system. These results demonstrate that the expression of this β 2.tubulin gene in zebrafish embryos is neural specific.

A new cyamodontoid placodont is named (Pse-phochelys polyosteoderma gen. et. sp. nov.) and described based on a three-dimensionally preserved specimen. The material comes from the Wayao Member of the Falang Formation (Carnian, Late Triassic) in Guizhou Province, southwestern china. The skull of Psephochelys shows a unique combination of characteristics observed in Psepho-derma and Placochelys, and the carapace is diagnostic of a new taxon as well. The ventral dermal armor of Psephochelys differs from all other known cyamodontoids in that it comprises irregular marginal osteoderms in loose contact with each other, and gastralia between them. The cranial suture pattern is in part difficult to analyze due to apparent co-ossification of elements, or poor delimitation of sutures. This affects primarily the demarcation of the nasal from the prefrontal, and the relation between the anterior part of the parietal, posterior ends of the frontals, and postfrontals. However, the postfrontal appears to enter the

Quaternary mammal fossils from north-east china (former Manchuria) have been collected and studied since the beginning of the century. But almost every previous study was based on the fossils from a certain site. There had no general study on the Quaternary mammal fossils found in the north-east china as a whole. The present paper is a part of the programme, led by Prof. Xu Qinqi,"The evolution of Quaternary mammal and its relationship with paleoclimatical variation". The plants are sensitive to climatical changes, their evolution has greatinfluence on that of the herbivores. So the programme began with the large herbivorous mammals, the Proboscidea, Perissodactyla and Artiodactyla (including omnivorous suids which are large consummers of plants). They can be summarized as follows (the extinct species are marked with an asterisk):

The close relatives of Ctenodactylidae were present early in Eocene of Asia. As basal members of early rodents, they are important for us to understand the early history of rodents. In the present paper a new genus and species, Hohomys lii, referred to Youmyidae, and a specirnen of gen. indet., referred to Cocomyidae, are described. They were collected from Yuhuangding Formation near Wangjiazhai Village, Xijiadian Town, Danjiangkou City (formerly Junxian County), Hubei. The taxa of the vertebrate fauna associated with these two new ctenodactyloid rodents are Rhombomylus ***, R. sp., Advenimus hubeiensis, A. sp., cf. Heptondon sp.,Asiocoryphodon conicus, Heterocoryphodon flerowi and Zhongvuanus sichuanensis etc., which suggest an age of late Early Eocene.
