Shenzianyuloma is an extinct genus of vetulicolians, represented by a single species, Shenzianyuloma yunnanense, from the Maotianshan Shale during Stage 3 (518 million years ago) of the Cambrian period. It is notable for having a compact body shape akin to that of an angelfish. The name of the genus is derived from the Chinese shénxiān yú (神仙鱼), meaning "angelfish", and an anagram of Mola.[1] Because of its notochord-like structure, depending on its phylogenetic position, it could belong to either an ancestral deuterostome with a primitive notochord-like structure or an archaic chordate-related phylum.[2]
