陕西宁强新元古代末期灯影组高家山段上部发现与Cloudina ,Sinotubulites等管状动物骨骼化石共生的大量微体奇异骨骼化石 ,其中的一些似与寒武纪早期的小壳化石有一定的亲缘 ,如形态奇特的铆钉状化石、腹足类化石等 ,证实寒武纪与前寒武纪生物界之间存在明显的连续性 ;奇异骨骼与陡山沱期生物也存在一定的相似性 ,如一些分枝的管状化石 ,这一化石组合具有承前启后的作用。该组合包含了可能的矿化后生藻类 (具各种分枝类型 )、矿化的蓝绿藻类化石等。种种迹象表明 ,在新元古代末期整个生物界发生了一次强烈的生物矿化事件 ,这一发现弥补了国内外新元古代末期矿化后生植物资料的空缺 ;磷酸盐化球状化石的研究已成为国内外研究的热点 ,本文所展示的球状化石由于形态多样 ,数量众多 ,内部结构各异 ,对其进行深入研究 ,可望在后生动物起源和早期演化研究方面取得突破
In the upper part of the Gaoshan section of Neoproterozoic Dengying Formation in Ningqiang, Shaanxi Province, a large number of bionic fossils with coexistence with tubular fossils such as Cloudina and Sinotubulites were found. Some of them may be related to the early Cambrian small shell fossils, Such as the unique shape of rivets fossils, gastropod fossils, confirmed that there is a clear continuity between the Cambrian and Precambrian biological world; strange bones and the Doushantuo period biological there are some similarities, such as some Branched tubular fossils, this fossil assemblage has the role of prophase Kai. The combination includes possible mineralized epiphytic algae (with various branch types), mineralized blue-green algae fossils, and the like. There are various indications that a strong biomineralization occurred in the entire bio-kingdom in the late Neoproterozoic. This finding made up for the vacancy of metaphyseal metaplasia in the late Neoproterozoic; the study of phosphated spherical fossils has become At home and abroad, the spherical fossils presented in this article have been able to make breakthroughs in the study of the origin and evolution of metazoans due to their diverse forms, large numbers and different internal structures.
