从广西西南部东攀、柳桥和蒎蓖三条剖面中,发现了保存精美、种类丰富的放射虫动物群.其中属于阿尔拜虫属(Albaillella)和新阿尔拜虫属(Neoalbaillella)的放射虫共计16个种,包括7个未定种.根据这些放射虫的地层分布,建立了两个放射虫化石带,从下至上为:Albaillella triangularis带和Albaillella yaoi带.基于共生的牙形石化石,将放射虫带与牙形石带作了对比,发现Albaillella triangularis带和Albaillella yaoi带分别可以与牙形石Neogondolella postwangi带和Neogondolella yini带对比. From the three sections of Dongpan, Liuqiao and Pinian grate in the southwestern part of Guangxi Province, the well-preserved and abundant radiolarian fauna have been found, of which the radiolarians belonging to the genus Albaillella and Neoalbaillella A total of 16 species, including seven undetermined species.Based on the stratigraphic distribution of these radiolarians, two radiolarian fossils have been established, from the bottom to the Albaillella triangularis zone and the Albaillella yaoi zone.Based on the symbiotic conodont fossils, The comparison of the radiolarian belt with the conodont zone revealed that the Albaillella triangularis zone and the Albaillella yaoi zone were comparable to the Neogondolella postwangi zone and the Neogondolella yini zone, respectively.
