| 1 | The Lantian biota:A new window onto the origin and early evolution of multicellular organisms显示文摘The Lantian biota at the Lantian Town of Xiuning County,Anhui Province,is preserved in black shales of the Ediacaran Lantian Formation.It yields some of the oldest known complex macroorganisms,including fan-shaped seaweeds and possible animal fossils with tentacles and intestinal-like structures reminiscent of modern coelenterates and bilaterians.The Lantian Lagerst tte sheds new light on the origin and early evolution of multicellular organisms in relatively quiet and deep environments soon after the Neoproterozoic Marinoan glaciation.The morphological complexity and diversity of early multicellular organisms may be closely related to sexual reproduction and alternation of generations.The fluctuation of oceanic redox conditions during this period may have played a role in the ecology and preservation of the Lantian biota. | YUAN XunLai CHEN Zhe XIAO ShuHai WAN Bin GUAN ChengGuo WANG Wei ZHOU ChuanMing HUA Hong | 2013 | Science China(Technological Sciences)2013，56，3： | 5 |
| 2 | Quantitative Analysis of Flabellophyton from the Ediacaran Lantian Biota, South China: Application of Geometric Morphometrics in Precambrian Fossil Research显示文摘As a more efficient quantitative method for morphological analysis, geometric morphometrics is applied to the flabellate fossils Flabellophyton including Flabellophyton lantianensis and Flabellophyton strigata from Neoproterozoic Ediacaran Lantian biota, South China. Both traditional morphometric analysis (including diverging angle, length, and width distribution) and geometric morphometric analysis including superposition of normalized area analysis, non-metric multidimensional scaling (n-MDS), Bray-Curtis similarity cluster analysis (CLUSTER) and analysis of similarities (ANOSIM)were performed. The results indicate there are great interspecific morphological differences between F. lantianensis and F. strigata, in addition to some intraspecific variations within each species. Here we preliminarily suggest that the previously defined Flabellophyton should be subdivided into 2 genera at least: one marked by the dark transverse striated structure, and the other without. This recharacterization and reclassification work still needs further careful observation and comprehensive analysis with large number of flabellate fossils combining morphology, structure, population, and community-ecology study. | WAN Bin YUAN Xunlai CHEN Zhe GUAN Chengguo PANG Ke TANG Qing RAO Xin | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 1 |
