摘要: The planktonic medusiform taxon Pararotadiscus guizhouensis (Zhao and Zhu, 1994) is one of the most abundant components Kaili Biota. Many specimens are in direct association with other taxa, including trilobites, brachiopods, hyolithids, echinoderms, algae, as well trace fossil Gordia. Four types interrelationships between P. associated fossils recognized: symbiosis, co-burial, attachment benthic taxa on carcasses, scavenging carcasses. These associations within Biota unique among occurrences Burgess Shale-type biotas worldwide provide important insights concerning ecological complexity Cambrian marine communities general.
