Period: Early Cambrian 518MA
Origin: China, Yunnan, Chengjiang biota
Size: 5 cm

Cricocosmia is an abundant palaeoscolecid worm endemic to the Early Cambrian Chengjiang Biota of Yunnan, China. It resembles modern priapulids, and holds a pivotal role in understanding the evolution of early ecdysozoans. It possessed paired lateral sclerites and paired ventral projections which have been compared with early panarthropod legs. It was a detritivore, living in shallow horizontal burrows, sometimes in great concentration.
