Lobopodia edit
Genus | Species | Material | Notes | Images |
---|---|---|---|---|

|
An unarmoured lobopodian, apparently closely related to Onychophora. The long, paired, cirriform structures at the end of the body could have been sensory, or perhaps represent viscera not externally present in life. |

|
|
A giant gilled lobopodian, closely related to and possibly synonymous with Pambdelurion. Also present in the Xiaoshiba Biota. |
Radiodonta edit
Radiodonta are a group of highly successful panarthropods. The Chengjiang Fauna includes a large number of Radiodont species, primarily from the clade Amplectobeluidae. While hurdiids are poorly known from the formation and surrounding region, several specimens attributable to the family have been discovered, but remain unnamed.

Multiple Specimens. |
A sessile, marine annelid tube worm of the family Serpulidae. Its affinities with the genus Serpula are controversial, since the genus is known mostly since Cretaceous strata. Although there are other fossils assigned to the genus on same age deposits of France. Presumably these specimens have fallen from their growth areas.[2] |
