Yicaris
Yicaris dianensis is a species of microscopic pancrustacean found in the Yu’anshan Formation, Yunnan Province, China. Yicaris' discovery is notable because its age suggests that true crustaceans already existed as far back in time as Early Cambrian, much earlier than other fossils known from the Middle and Late Cambrian. Its closest living relatives are believed to be Cephalocaridans.
