Scleractinia is displayed at 247.2–0 Ma as Oliver’s review-bounded Middle Triassic–Holocene fossil-to-living range; it is not the Paleozoic molecular-clock estimate, a symbiosis-event window or an exact crown-origin date. This navigation entry is not a phylogeny or a complete taxon dossier.

Claim ledger
divergence-time · medium
A four-locus relaxed clock places sampled deep scleractinian splits in the Paleozoic, substantially before their skeletal record; this posterior estimate is model-dependent and not a fossil occurrence or exact Scleractinia origin.

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
