Mitochondrial protein-coding sequences from 103 genera and 28 families test octocoral relationships, but weak deep resolution leaves the root and several higher groups unsettled.

Mitochondrial analysis sampling 103 genera in 28 families; deep resolution and the octocoral root remain limited.
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.
