    湖北宜昌地区晚泥盆世黄家磴组植物化石新材料及其意义

    New material of Late Devonian plants fossils from Huangjiadeng Formation in Yichang area, Hubei, China and its significance

    • 摘要: 报道了宜昌官庄一带晚泥盆世黄家磴组的植物化石,共计6属6种(其中包括1个相似种和1个未定种),即纤原始鳞木(相似种)Prorolepidodendron cf. scharyanum Krejci,大拟鳞木Lepidodendropsis arborescens (Sze) Sze,平圆印木Cyclostigma kiltorkense Haught.,亚鳞木(未定种)Sublepidodendron sp.,斜方薄皮木Leptophloeum rhombicum Dawson和脐根座Stigmaria ficoides (Sternberg) Brongn。这些植物化石的发现,不仅丰富了黄家磴组植物组合的内容,为确定该组的时代提供了充分的古生物证据,而且表明以往归入中泥盆世的纤原始鳞木Prorolepidodendron scharyanum Krejci的地质时限可上延至晚泥盆世黄家磴期早、中期。

       

      Abstract: This paper describes the plants fossils found firstly from the Huangjiadeng Formation in Guanzhuang area near Yichang, including six genera, six species, namely Prorolepidodendron cf. scharyanum Krejci sp., Lepidodendropsis arborescens (Sze) Sze, Cyclostigma kiltorkense Haught.,Sublepidodendron sp., Leptophloeum rhombicum Dawson and Stigmaria ficoides (Sternberg) Brongn. The discovery of plants fossils, not only has enriched the plant combination and more paleontology proof of division and correlation of Huangjiadeng Formation, but also has indicated the geological time-frame of the plants fossils can be extended to the Late Devonian.
