The distribution of Rugose Corals between the end of the Frasnian and the early Tournaisian is reviewed in four selected regions (Belgium and surrounding areas, German cephalopod facies, Poland, Omolon). Four "paleontological events" are distinguished : extinction of most of the Devonian-type Rugose Corals at the end of the Frasnian; development of a new fauna at the beginning of the Upper Famennian; increase and diversification of corals during Strunian; extinction of most of the Strunian corals and replacement by a Tournaisian-type coral fauna at the Devonian-Carboniferous boundary. These seems to be the result of eustatic and probably also climatic fluctuations (variations in sea water temperature).
