Occurrence of Carboniferous corals from the Geumcheon Formation of Danyang area, Korea

Abstract

Two species of Carboniferous coral, Arachnastraea manchurica and Diphyphyllum delicatum, are described for the first time from the upper part of the Geumcheon Formation of the Danyang area, Korea. They were previously reported as Devonian corals, Disphyllum sp. and Phillipsastraea sp. Associated fossils are fusulinids, including Beedeina schellwieni, B. siviniensis, B. samarica, B. sp., Fusulina cylindrica, F. sp., Fusulinella mosquensis, Fusulinella provecta, Neostaffella sphaeroidea, and Ozawainella turgida. Occurrence of these corals and fusulinids suggests that the upper part of the Geumcheon Formation is middle Moscovian in age.
