... affinities with the Microconchida, an extinct order of possible lophophorates. Although characteristically Palaeozoic, microconchid tube-worms survived the Permian mass extinction before being replaced in late Mesozoic ecosystems by true Spirorbis . Recent Spirorbis is stenohaline but spirorbiform...

Tentaculitoids were possibly lophophorates in the stem-group of the phoronids ( Taylor et al., 2010 ). Thus...
