List of prehistoric hexacoral genera

This list of prehistoric hexacorals (hexacorallia) is an attempt to create a comprehensive listing of all genera that have ever been included in the hexacorallia which are known from the fossil record. This list excludes purely vernacular terms. It includes all commonly accepted genera, but also genera that are now considered invalid, doubtful, or were not formally published, as well as junior synonyms of more established names, and genera that are no longer considered scleractinia.
