GeoJSON
Fossils
The Fukuji Fm consists mainly of limestone with corals and stromatoporoids as the main allochemical constituents along with minor felsic tuff layers (Kamei 1962; Tsukada 2005). Early-Middle(?) Devonian fossils, including corals, conodonts, trilobites and brachiopods, have been obtained from this formation (e.g., Kamei 1952,1955b; Kamei& lgo I955: Kobayashi & Igo 1956; Hamada 1959a, b; Koizumi & Kakegawa 1970; Research Group for the Paleozoic of Fukuji 1973; Okazaki I974; Ohnn I977; Niikawa I980; Kuwano 1986, 1987).
