| 摘 要： | 大塘坡组黑色页岩为中国扬子地台新元古代间冰期沉积。在湖北长阳古城和湖南花垣民乐的大塘坡组黑色页岩中检测到沟鞭藻的生物标志化合物——甲藻甾烷，这是目前国内地质时代最早的甲藻甾烷的检出报道，结合其它化石资科，表明沟鞭藻与其它真核藻类的系统发生至少在新元古代就已经完成、这与真核生物在新元古代冰期结束前就有很大发展的推测相一致。

| Abstract: | Dinosterane bas been detected from the Neoproterozoic Datangpo black shales at Changyang, Hubei Province and Huayuan, Hunan Province, South China. The Datangpo Formation is the Neoproterozoic interglacial deposits that underlies the Nantuo tillites and overlies the Gucheng diamictites. The report is earliest in earth history in China until now. In combination with the late Neoproterozoic algal fossils, the datum of dinosterane supports the view that the dinoflagellate and other eukaryotic algal phyla were diversified no later than the Neoproterozoic glaciations. |
