| Abstract: | During the last two years, I have received many samples of Sinian rocks from eastern Yunnan and western Hupei. By careful examination, some microfossil flora were discovered. The present paper is a primary report of the results. In western Hupei, spore fossils Leiominascula, Zonosphaeridium, Pseudozonosphaeridium, Stenomarginata etc. and plant remains Laminarites etc. are encountered in Dengying and Doushantuo formations. Also spore fossils Leiominuscula, Pseudozonosphaeridium etc. and plant remain Laminarites are found in Deushantou and Nantuo formations in eastern Yunnan. All mentioned microfossils are preserved in black shales and limestones. The spores are entirely referred to the primitive psytopfytales and single cell algae. Their shapes are commonly simple, circuler, ovaloid or elliptical and with folds, exine thin and smooth, the diameter ranging from 7 to 35μ. |
