Marrella, a well-known and important component of the Burgess Shale, was only previously found in the Burgess Shale and in the Kaili Biota. An exoskeleton attributed to Marrella is described herein from the lower part of the Balang Formation (Cambrian Series 2) in Paiwu, northwestern Hunan Province, China. It represents not only the third locality where the genus is found, but also the oldest known occurrence of this taxon.
