贵州副圆盘藻Pararotadiscus guizhouensis（Zhao and Zhu，1994）是凯里生物群中最丰富的类群之一。许多标本与其他分类群直接相关，包括三叶虫，腕足动物，舌骨动物，棘皮动物和藻类，以及Gordia的痕迹化石。贵州原螯虾与伴生化石的关系可分为共生、共埋、底栖动物对贵州原螯虾尸体的附着和对贵州原螯虾尸体的清除等4种类型。贵州P. guizhouensis在凯里生物群中的组合在世界范围内Burgess页岩型生物群中的中型化石中是独一无二的，并为凯里生物群和寒武纪海洋生物群落的生态复杂性提供了重要的见解。
The planktonic medusiform taxon Pararotadiscus guizhouensis (Zhao and Zhu, 1994) is one of the most abundant components of the Kaili Biota. Many specimens are in direct association with other taxa, including trilobites, brachiopods, hyolithids, echinoderms, and algae, as well as the trace fossil Gordia. Four types of interrelation ships between P. guizhouensis and associated fossils are recognized: symbiosis, co-burial, attachment of benthic taxaon P. guizhouensis carcasses, and scavenging of P. guizhouensis carcasses. These associations of P. guizhouensis within the Kaili Biota are unique among occurrences of medusiform fossils in Burgess Shale-type biotas worldwide and provide important insights concerning ecological complexity in the Kaili Biota and in Cambrian marine commu nities in general.
