| | Burgess Shale trilobites |
 | | The Burgess Shale biota, first discovered by Charles Doolittle Walcott in 1909, was revolutionary as the first indication of the great diversity of soft-bodied animals that normally do not fossilize. |
 | | As in the Chengjiang lagerstatte, soft-bodied animals are preserved in the Burgess Shale, revealing a great diversity of early arthropods, as well as such curiosities as anomalocaridids and Hallucigenia. |
 | | It is notable that the trilobite fauna of the Burgess Shale, being a late Middle Cambrian locality, is not dominated by Redlichiida as at Chengjiang, but by a mix of Ptychopariida, Corynexochida, and Agnostida. |
