陕南晚震旦世高家山生物群中骨骼化石的电镜扫描显示 ,Sinotubuliteslevis壳壁中具有丰富的磷酸盐化球状和丝状体 ,可分为 3种不同类型的微生物组构 :1)由相互缠绕的丝状体所组成的藻席状组构 ;2 )由外表面成莓球状 ,内部中空的球状体紧密堆叠所形成的组构类型 ;3)由表面极为光滑的球状体堆叠所形成的组构。它们可能分别代表不同类型的矿化蓝藻 ,依此推断微生物在S .levis壳壁磷酸盐化过程中起着重要作用。在共生的Sinotubulitesbaimatuoensis和Cloudina壳壁上 ,极少或完全不存在这些磷酸盐化组构表明微生物的磷酸盐化作用具有专属性 ,可能由壳壁微结构所决定 ,具多层状壁的S .levis可能与具许多有机质纹层的多毛类壳壁关系密切。
Scanning electron microscopic scanning of skeleton fossils in the Late Sinian Gaoshanashan biota in southern Shaanxi showed that the Sinotubulites levis shell wall is rich in phosphated globular and filamentous bodies and can be divided into three different types of microbial structures: 1) 2) the type of structure formed by the outer surface of a raspberry-spherical, closely hollow interior spheroid; 3) the formation of a very smooth spherical spheroid stack Organization. They may represent different types of mineralized cyanobacteria, respectively, suggesting that microorganisms play an important role in S. levis shell phosphatation. In the symbiotic Sinotubulites baimatuoensis and Cloudina shell walls, little or nonexistence of these phosphatation structures suggests that the phosphatation of microorganisms is specific and may be determined by the shell-wall microstructure with S-layered walls. Levis may be closely related to the polychaete shell wall with many organic textured layers.
