1989年报道的早寒武世澄江化石库的云南火把虫(FacivermisyunnanicusHouetChen)躯体的前部具有5对触手,而尾部被解释成简单的尖缩状;并认为可能与环节动物的多毛类相关.此后,它又被解释为与五口动物或触手冠动物等类群具有亲缘关系.最近西北大学早期生命研究所发现了完整云南火把虫标本:完整的云南火把虫不仅显示了躯干前端的5对叶足状附肢,而且还保存了具2~3圈钩刺的倒梨形尾部.基于这些重要形态学信息,本文作者对云南火把虫的分类位置予以重新界定:其5对叶足状附肢与神奇啰哩山虫(MiraluolishaniaLiuetShu)的前躯干附肢十分相近,似为同源构造,因而很可能与叶足类具有较近的亲缘关系.此外,云南火把虫的5对叶足状附肢对于探索叶足类动物和节肢动物附肢的起源更具有重要的科学意义.
Reported in 1989, the Early Cambrian Chengjiang fossil library Yunnan Fuzhou insects (FacivermisyunnanicusHouetChen) body in front of the body with 5 pairs of tentacles, and the tail was interpreted as a simple pointed shape; and that links may be associated with polychaete animals. , Which in turn is interpreted as having a genetic relationship with a group of five animals or tentacle-crowned animals.A recent study by the Institute of Early Life Sciences at Northwestern University found a complete specimen of Yunnan torpedo: a complete Yunnan torchworm not only showed five pairs of leaf-foot Shaped appendages, but also preserved inverted pear-shaped tails with 2 to 3 largings.Based on these important morphological information, the author redefined the classification of the torchworm in Yunnan: The forelimb appendages of Miraluolishania Liuethu are very similar and seem to be homologous structures and thus probably have close genetic relationship with the leaf footer.Moreover, Exploring the origins of leaf appendages and arthropods has more important scientific significance.
