HIERARCHICAL CLASSIFICATION OF THE PHYLUM PHORONIDA (HATSCHEK 1888)

EUKARYA> UNIKONTA> OPISTHOKONTA> ANIMALIA> METAZOA> BILATERIA> PROTOSTOMATA> SPIRALIA> TROCHOZOA> BRACHIOZOA> PHORONIDA

These enigmatic organisms seem to represent a remnant of a large Paleozoic diversity. As such, the remaining diversity is not sufficient to provide a taxonomy in which higher taxa can be agreed upon. Nevertheless, we give a provisional taxonomy with one class (we call Phoronata) and a single order.
