Claim ledger
Octocorallia has no supported scalar crown range in the cited evidence: the mitochondrial phylogeny samples living octocorals but supplies no fossil or calibrated crown boundary, so the former 0–0 placeholder is withheld.
claim:taxon:octocorallia:range-boundary-rc50Known limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
