【摘要】 文中记述了所发现的遗迹化石共计13遗迹属、16遗迹种,其中3个新遗迹属、6个新遗迹种和1个未定属种。丰富了我国遗迹化石的材料并讨论了遗迹化石及共代表的沉积环境间的关系。对遗迹化石及沉积物的研究表明:柳江盆地中寒武世的沉积环境转变过程是泻湖—局限潮下带—正常浅海。更多还原

【Abstract】 Trace fossils described in this paper collected from the lower part of the Xuzhu-ang Formation (Middle Cambrian) at Funing County, Hebei. It consists of 13 ichnog-enera, 16 ichnospecies, including 3 new ichnogenera, 6 new ichnospecies, 1 gen. et sp. indet. This assemblage of traee fossils is named the "Xuzhuang ichnus community", which occurred in shales and fine sandstones of the lower part of the Xuzhuang Formation.The ichnological study indicates that the lower part of Xuzhuang Formation represents a sedimentation of less agitated restricted sea, while the upper part of Xuzhuang Formation represents a sedimentation of normal shallow sea.更多还原
