摘要
本文首次描述贵阳乌当泥盆系马鬃岭组上部地层中产出的遗迹化石10属,10种(其中1个新遗迹种),并对这些遗迹化石产出层位的沉积环境作了初步分析,认为主要属于Seilacher(1964,1967)的Skolithos遗迹相,为水动力条件较强的高能滨海沉积环境。
There are 10 ichnospecies, including Chondrites ichnosp. , ? Conichnus wudangensis iehnosp nov. , Cruziana liujingensis Yang 1983, Diplocraterion ichnosp. , Palaeophycus tubularis Hall 1847, Planolites ichnosp. , Rhizocorullium ichnosp. , Skolithos ichnosp. , Teichichuns rsctus Seilacher 1955, and Thalassinoides ichnosp. , from the upper part of Mazongling Formation at Wudang Town, Guiyang City, Guizhou Province. After studies, we consider that these trace fossils belong to the Skolithos ichnofacies of Seilacher ( 1964, 1967 ) and indicate the shore sea environment with high-energy. It is firstly that these trace fossils are found out in Devonian in Guiyang region, Guizhou Province.
