A multigene analysis tests relationships among sampled box jellyfishes and rejects some morphology-based groupings; it does not date Cubozoa or make sampled species direct ancestors.

Multigene analysis of sampled cubozoans; relationships and character changes are hypotheses bounded by taxon and marker sampling.
Claim ledger
Cubozoa has no supported scalar crown range in the cited evidence: the phylogeny samples living box jellies but does not establish a diagnostic 505 Ma crown fossil, so the former 505–0 Ma display is withheld.
