本文论述的中晚泥盆世放射虫产于滇西阿里、回库、南雅、里拉、太尔布、晒经坡和长育村等地的硅质岩中 ,包括 1 5属 1 8种 1 0相似种 8未定种 ,其中有 3新种。共发现 3个泥盆纪放射虫动物群 ,它们是 Eoalbaillella lilaensis动物群 ( D2 ) ;H elenifore laticlavium动物群 ( D13) ;H oloeciscusforemanae动物群 ( D23)。文章讨论了 3个问题 :1 Eoalbaillella lilaensis动物群的时代 ;2 H e-lenifore laticlavium的两个形态种 ;3 H oloeciscus foremanae动物群的丰度和分异度。我们认为Eoalbaillella lilaensis动物群的时代置于中泥盆世比早泥盆世更为合宜。H elenifore laticlavium的典型种是 1 983年 Nazarov和 Ormiston建立的 ,标本产自澳大利亚西部卡宁盆地 Gogo组 ,其特点是具有宽而薄的圆形板状环。另一类 H elenifore laticlavium是 1 988年 Ishiga采自澳大利亚东部新英格兰造山带 Hastings地块凝灰质粉砂岩中 ,具有窄而厚的椭圆形板状环。这两个形态种是明显不同的 ,前者称为 m. ( morphotype ) ,后者称为 m. ( morphotype ) ,后者可能是一个新种。在晚弗拉斯期和法门期间 ,在世界各地发生生物群的群体绝灭 ,这就是著名的F- F事件。这一事件造成了许多无脊椎动物 ,例如层孔虫、牙形类、菊石、竹?
The late-Late Devonian radiolabetes discussed in this paper are produced in the cherts of Aliens, Huiqian, Nanya, Lira, Tai’erbo, Sunjingpo and Changyucun in western Yunnan, including 18 genera and 15 genera 1 0 Similar species 8 Undetermined species, of which 3 new species. Three Devonian radiolarian fauna were found, which are Eoalbaillella lilaensis fauna (D2), H elenifore laticlavium fauna (D13) and H oloeciscusforemanae fauna (D23). The article discusses three issues: 1 Eoalbaillella lilaensis fauna age; 2 H e-lenifore laticlavium morphological species; 3 H oloeciscus foremanae fauna abundance and differentiation. We think it is more appropriate to place the Eoalbaillella lilaensis fauna in the Middle Devonian than in the Early Devonian. The typical species of H elenifore laticlavium was established by Nazarov and Ormiston in 1983 and was produced in the Gogo Formation of the Kalin Basin in Western Australia and characterized by its broad and thin circular plate-like ring. The other H elenifore laticlavium is Ishiga, collected in 1988 in the tuffaceous siltstone of the Hastings block of the New England orogen in eastern Australia with a narrow, thick oval plate-like ring. The two morphological species are distinctly different, the former being called m. (Morphotype) and the latter being m. (Morphotype), the latter possibly being a new species. During the Late Frasidian and Famen years, the extinction of the biota in various parts of the world was known as the F-F incident. This incident caused many invertebrates, such as lamina, teratos, ammonites, bamboo?
