The macroscopic algae fossils from Shibantan bituminous limestone of Dengying Formation in the Xiadong area, Hubei province were studied. There are one genus and three species (including two new species) and one new macroscopic algae fossils with monopodial branching character (genus and species are unidentified) from the Sixi section. Monopodial-branching type fossil represents the first macro-algae fossil with the monopodial branching discovered in the terminal Ediacaran Dengying and equivalent formations in South China. Vendotaenia sixiense new species and Vendotaenia pavimentpes new species are the algae fossils with branching and holdfast, respectively. The new discovery suggests that the morphology of macroscopic algae fossils might be more complex than previous think, and has the great significance to the evolution research of the early multicellular macroalgae.

This paper focuses on the influence external economies of scale brought by industrial agglomeration and internal economies of scale brought by industrial organization have on pollution emission intensity. This research takes SO₂, soot, polluted water as the examples and two digits manufacturing industrial divisions as the research subjects. Through spatial distribution analysis and penal data econometric analysis during the time from 2005 to 2009, the authors find that the relationship between gini and pollution intensity is positive, state owned and group owned enterprises ratios are negative related to pollution intensity of SO₂ and soot, while private and foreign investment enterprises ratios are positive related to pollution intensity. The result shows that industrial pollution is influenced by the trend of marketization, which suggests that the authority may improve the environmental regulations systems and the supervision power, and local government should improve the pollution dissolving facilities’ effectiveness and pollution control efforts within industrial clusters.
