The Eoil Flora, from two sites of the Gampo Conglomerate and one site of the Eoil Formation in the Eoil Basin, consists of 17 species belonging to 11 families and two angiosperms of uncertain systematic position. The following 14 genera are represented: Equisetum, Sorbus, Ulmus, Fagus, Pterocarya, Alnus, Populus, Salix, Decodon, Acer, "Alangium", Fraxinus, Dicotylophyllum and Monocotylophyllum. The flora consists mainly of deciduous broad-leaved tree species, dominated by Alnus arasensis followed by "Alangium" aequalifolium. The Eoil Flora represents riparian and surrounding vegetation, as indicated by the mode of fossil occurrence, lithology and sedimentary facies of the plant-bearing beds. The Eoil Flora is comparable to the Janggi Flora of the Pohang area and the Aniaitype floras of Japan. Aniai-type floras, including the Eoil Flora, share features common to broad-leaved deciduous vegetation under mesic to humid temperate climates. This flora also characterizes the paleoenvironment of this region just before the tectonic event associated with the opening of the East Sea (Sea of Japan).
