贵州东部寒武系杷榔组发育,化石丰富,产有杷榔动物群;其中掘头虫类、莱德利基虫类三叶虫保存好,序列完整,提供了研究这些类群属种个体发育的重要材料。本文据杷榔组Redlichia(Pteroredlichia)chinensis(Walcott,1905)的300多块标本的分析数据,详细讨论和重点研究了其从幼虫期、分节期至成虫期个体发育特征,分析各个阶段的形态变化及个体发育演化趋势。丰富了R.(Pteroredlichia)chinensis个体发育的资料,对莱德利基虫属种厘定起到积极的作用,提供了属种分类对比的重要证据。
The Cambrian of the Cambrian in eastern Guizhou developed and fossilized, producing the beluga fauna. Among them, the doufacidae and the Lidlichia trilobite were well conserved and the sequences were complete, providing an insight into the individual development of these species Important material. Based on the analysis data of more than 300 specimens of Redlichia (Pteroredlichia) chinensis (Walcott, 1905), this paper discussed and analyzed the characteristics of individual development from larval stage, cut stage to adult stage, Changes and individual development trends. It enriches the individual developmental data of R. (Pteroredlichia) chinensis and plays a positive role in the determination of Liddee, providing important evidence for taxonomic comparison.
