Systematic review whose abstract explicitly separates the Early Ordovician–end-Permian Tabulata, Middle Ordovician–end-Permian Rugosa and Middle Triassic–Holocene Scleractinia records.
Rugosa is displayed at 471.3–251.9 Ma as Oliver’s review-bounded Middle Ordovician–end-Permian fossil record; the numerical conversion is not a specimen-level FAD/LAD or a claim of uninterrupted global occupancy.
claim:taxon:rugosa:range-boundary-rc50Tabulata is displayed at 486.85–251.9 Ma as Oliver’s review-bounded Early Ordovician–end-Permian fossil record; the numerical conversion is not a specimen-level FAD/LAD or a claim of uninterrupted global occupancy.
claim:taxon:tabulata:range-boundary-rc50Scleractinia 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.
