Abstract: Chengjiangocaris kunmingensis sp. nov. and Fuxianhuia xiaoshibaensis sp. nov.— early Cambrian fuxianhuiid fossils from a new Lagerstätte in Yunnan, China—show that ancestral arthropods had cephalic organization that included an antenniform first appendage, which corresponds to the deutocerebral head segment of modern arthropods.
