本文描述了贵州金沙岩孔镇长岩沟下寒武统(纽芬兰统—寒武系第2统)牛蹄塘组底部黑色页岩中呈碳质薄膜保存的宏观藻类化石,共3属3种:美丽遵义藻Zunyiphyton pereleganus Yang et Zhao,1999,云南中华细丝藻Sinocylindra yunnanensis Chen et Erdtmann,1991,文德带藻(未定种)Vendotaenia sp.。该组合中主要分子是Zunyiphyton pereleganus和Vendotaenia sp.,它们也是遵义牛蹄塘组宏观藻类组合中最主要的分子。而遵义牛蹄塘组宏观藻类组合的另一特征分子贵州约克那斯藻Yuknessis guizhouensis及底栖固着型藻束状陡山沱藻Doushantuophyton comet在金沙岩孔牛蹄塘组宏观藻类化石组合中未见,说明产于浅水台地的牛蹄塘生物群宏观藻类组合既具有广泛的一致性也具有一定的差异性。
This paper describes the macro algal fossils preserved in carbonaceous film in the black shale at the bottom of the Lower Cambrian (Newfoundland-Cambrian System) Niutiotang Formation in the Changyan ditch, Yan Kong, Guizhou, Species: Zunyiphyton pereleganus Yang et Zhao, 1999, Sinocylindra yunnanensis Chen et Erdtmann, 1991, Vendotaenia sp. The main molecules in this assemblage are Zunyiphyton pereleganus and Vendotaenia sp., Which are also the most important molecules in macroscopic algae assemblage in Zunyi Niutitang group. However, another characteristic molecule of the macroscopic algae assemblage in the Zunyi Niutizang Formation was Yuknessis guizhouensis and Doushantuophyton comet of the benthic fixative algae bundles in the macroscopic algal fossil assemblage , Indicating that the macro algae assemblage of the Niutizang biota produced in the shallow water platform has both broad consistency and certain differences.
