| 摘 要： | 本世纪三十年代初,我国古生物学家尹赞勋先生曾详细研究采自滇东和川西南的一些 Cruziana 遗迹化石(尹赞勋,1933)。他首次在我国介绍了二叶石(Bilobites)这一名称同遗迹属名 Cruziana 的关系;讨论了三叶虫可能是 Cruziana 的遗迹动物;并系统描述了上述 Cruziana A,B,C 三种类型。这篇著作对研究我国三叶虫遗迹化石开创了方向,奠定了基础。

| Abstract: | The Ordovician trilobite burrows Cruziana(Bilobites)are remarkably widespread in eastern Yunnan and south-western Sichuan(Yin T.H. 1933, Xiong Yongxian 1944).The Lower Ordovician(Arengian)trace fossil community Cruziana rugosa d’Oro-bigny described from Hongshiyian Fm of Wuding, eastern Yunnan. It contains trilobite burrows: Cruziana rugosa d’Orbigny, Cruziana furcifera d’Orbigny, Cruziana yinin. iehnosp. Cruziana sp.; trilobitite walking tracks Dimorphichnus Seilacher, trilobite swimming grazing trail Monomorphichnus Crimes, resting trace Isopodichuns and other trace fossils.Also discussed in this paper are the depositional environment and the stratigra-phical range of the Cruziana rugosa community from Hungshiyian Fm and its geographical distribution in eastern Yunnan and south-western Sichuan. |
