Iotuba chengjiangensis (sometimes mis-spelt Lotuba[2]) is a 515 million year old Cambrian worm known from the Chengjiang biota.[3] Originally interpreted as a phoronid, the organism is now recognized as an annelid cage worm affiliated with the Flabelligeridae and Acrocirridae, which Zhang et al grouped together in the new superfamily Flabelligeroidea.[1]
