    Not 100% sure what it is - could be either a rare Yunnanozoon lividum Hou, Ramsköld & Bergström, 1991, a Hemichordate or - more likely Haikouella lanceolata Chen, Huang & Li, 1999, a Chordate. Even Haikouichthys ercaicunensis Shu, Conway Morris, Han & Zhang, a primitive fish, is still a posibility.
