Bilateria/Triploblasts (unranked)?

Planulozoa is a clade of animals that includes the superphyla Cnidaria (jellyfish, hydrozoans, sea anemones, corals, etc.) and the Bilateria (all complex animals with bilateral symmetry, including arthropods, molluscs, vertebrates, etc.).[2][3] The designation Planulozoa may be considered a synonym to ParaHoxozoa, which also contains Placozoa. Within Planulozoa, the Placozoa may be a sister of Cnidaria to the exclusion of Bilateria.[4][5][6][7] The clade excludes basal animals such as the Ctenophora (comb jellies),[8][9][3] and Porifera (sponges).[10][11][12] Although this clade was sometimes used to specify a clade of Cnidaria and Bilateria to the exclusion of Placozoa (against the original intention of its proposal), this is no longer favoured due to recent data indicating a sister group relationship between Cnidaria and Placozoa,[13] another study still supports Placozoa as sister to Cnidaria+Bilateria.[14] The phylogenetic tree indicates approximately how many millions of years ago (mya) the lineages split. Here, Planulozoa is shown sans Placozoa.[15][16][17] Planulozoa are associated with the emergence of the Zoc and ZF-NC gene domains.[18]
