寒武纪最早期层位中获得的离散骨片化石 H alkieria和 Microdictyon,已在较高层位的特异埋藏化石群中找到了它们的完整生物躯体 ,它为研究离散骨片化石的自然分类和生物亲缘提供了直接证据。本文通过寒武纪最早期钉状化石的形态、对称性、壳质成分、矿化特征的对比 ,提出了离散骨片化石织金钉 ( Zhijinites)和拟织金钉 ( Parazhijinites)与澄江动物群中的怪诞虫( H allucigenia)和爪网虫 ( Onychodictyon)等体表上的钉状物有近亲关系 ,它们可能同属于多足缓步类 ( Tardipolypoda)。 The sequestered fossil fragments, H alkieria and Microdictyon, obtained in the earliest Cambrian strata, have found their complete biological body in the higher-level specific burial fossils. It is a study of the natural taxonomy and biology of discrete fossil bones Relatives provide direct evidence. Based on the comparison of morphology, symmetry, crustal composition and mineralization characteristics of the earliest pegmatitic fossils in Cambrian, this paper proposed the relationship between the diaspore fossil Zhijinites and Parazhijinites and the Chengjiang fauna (Allucigenia) and onychodon (Onychodictyon) on the surface of the spikes have close relatives, they may belong to the class of Tardipolypoda (Tardipolypoda).
