(Geology), Science reports of Niigata University. (Geology)}, month = {Mar}, note = {As the third fascicle, this paper describes two species of heliolitid tabulate corals, namely Heliolites porosus (Goldfuss, 1826) and H. sp. cf. H. opacus (Dubatolov, 1963), from the Kotaki\narea, Niigata Prefecture, central Japan. The examined specimens were found in Mesozoic conglomerate. This discovery of H. porosus suggests that the coral-bearing limestone\npebbles are Givetian (late Middle Devonian) in age. Besides the type locality in Europe, this species is widely known to occur from North Africa, Asia and Australia. Another species\nresembles closely Heliolites opacus (Dubatolov, 1963), from the Eifelian to Givetian (lower to upper Middle Devonian) of southern Siberia, with exception of slight differences of\ntabularium diameters.}, pages = {1--6}, title = {Devonian tabulate corals from pebbles in Mesozoic conglomerate, Kotaki, Niigata Prefecture, central Japan Part 3: Heliolitida}, volume = {31}, year = {2016} }
