内容記述
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 Kotakiarea, Niigata Prefecture, central Japan. The examined specimens were found in Mesozoic conglomerate. This discovery of H. porosus suggests that the coral-bearing limestonepebbles 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 speciesresembles closely Heliolites opacus (Dubatolov, 1963), from the Eifelian to Givetian (lower to upper Middle Devonian) of southern Siberia, with exception of slight differences oftabularium diameters.
