Kingdom Animalia Genus †Iotuba | Phylum incertae sedis Species †I. chengjiangensis | |
Iotuba chengjiangensis is a problematic Cambrian fossil with a U-shaped gut and tentacles, known from the Chengjiang biota. Originally interpreted as a phoronid, its affinity is currently disputed. It, and the possibly-synonymous taxon Eophoronis, resemble the 'priapulid' Louisella.
