A systematic synthesis recognizes Hexacorallia within Anthozoa while reviewing competing internal relationships and uneven diversity knowledge; it supplies a classification framework, not a precise origin date.

Claim ledger
Hexacorallia has no supported scalar crown range in the cited evidence: the classification review does not justify transferring a 425 Ma Paleozoic coral occurrence to crown Hexacorallia, so the former 425–0 Ma display is withheld.
claim:taxon:hexacorallia:range-boundary-rc50Known limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
- PBDB external identifier withheld: accepted-rank-mismatch.
