The Early Cretaceous Okurodani Formation, Tetori Group, near Shokawa village, Gifu Prefecture, Japan, has yielded a mixed assemblage of terrestrial and aquatic small vertebrates, including the fragmentary remains of a frog (ilium, vertebra) and a salamander (vertebra). These are the first Mesozoic lissamphibians recorded from Japan, and some of the oldest from Asia. The ilium is of rather primitive form and suggests a frog of basal grade, that is outside the Discoglossanura.
