中文摘要:笔者在研究云南东部中泥盆世和晚泥盆世早期孢子的过程中,发现丰富的大孢子.并进行了研究.本文图示的大孢子为8个属、30个种和变种.其中新种8个即;Verrucisporites reticuloides,V.lunanensis,Biharisporites microspinosus,Trichodosporites mirabilis,Nikitinsporites yunnanensis,N.sinensis,N.maximus和Lagenicula verrucosa等。云南东部中泥盆世和晚泥盆世早期大孢子组合基本上可与加拿大北极地区同期地层中的大孢子组合进行比较,亦可与西欧、原苏联和中国有关地层中的大孢子进行对比.该组合的研究对泥盆纪植物演化,地层划分与对比,古气候和沉积环境的研究有着重要的意义. |

Abstract:Profuse and wel preserved assemblages of megaspores have been recovered from the Middle and early Upper Devonian in eastern Yunnan Province. Thiry species and varities of the megaspores are recognzed, and disributed among 10 genera, including eight new species: Verrucisporites reticuloides, V. lunanesis, Biharisporites microspinosus, Trichodosporites mirabilis, Nikitinsporites yunnanensis, N. sinensis, N. maximus, and Lagenicula verruosa. |
