Oesia disjuncta is a monospecific genus known from the Middle Cambrian Burgess Shale. 1147 specimens of Oesia are known from the Greater Phyllopod bed, where they comprise 2.18% of the community.^[1] Despite some similarities to the chaetognaths,^[2] its affinity is unknown, though recent data suggest it may be affiliated with hemichordates.^[3]^[4]
