A diverse assemblage of moderately well-preserved radiolarians occurs in the Ordovician cherts of the Crawford Group in the Southern Uplands terrane of the Scottish borders. A total of 8 genera and 11 species are described. Taxa present correlate to the Middle Ordovician Pygodus anserinus biozone. Key species identified include: Proventocitum procerulum, Inanigutta gansuensis, Inanigutta sp. cf. I. complanata, Inanibigutta sp. cf. I. verrucula, Inanibigutta sp. cf. I. pinglianensis, ?Inanibigutta inconstans, ?Inanihella penrosei, Haplentactinia armillata, ?Oriundogutta ramificans and Syntagentactinia sp. A new species Haplotaeniatum albaensis is introduced here and described on the basis of details of skeletal architecture observed using microcomputed tomography, demonstrating the potential of this technique as a tool for improving the understanding of radiolarian taxonomy.

来自苏格兰克劳福德组的中奥陶纪（达里维利安）放射虫

在苏格兰边界南部高地地体的克劳福德组奥陶纪燧石中出现了保存完好的放射虫的多样化组合。共描述了8属11种。现在的分类群与中奥陶世有关鹅尾猴生物区。确定的主要物种包括：原产地原产地,甘肃茯苓,伊纳尼古塔sp。参看。一、蜉蝣,伊尼比古塔sp。参看。一、疣,伊尼比古塔sp。参看。一、平莲, ?无常无常, ?粉虱,栀子花, ?Oriundogutta ramificans和Syntagentactiniasp。一个新物种白花单胞菌此处介绍并基于使用微计算机断层扫描观察到的骨骼结构细节进行描述，证明了该技术作为提高对放射虫分类学理解的工具的潜力。
