The late Ediacaran Jiangchuan biota, from the Dengying Formation in eastern Yunnan, is well-known for its diverse macroalgal fossils, opening a window onto eukaryotic-dominated ecosystems Neoproterozoic of South China. Although multiple lines evidence suggest that metazoans had already evolved by Ediacaran, animal fossils have not yet been formally described this locality. Here, we report putative disc-shaped macrofossil
