The first record of the Early Cretaceous freshwater fish, Wakinoichthys aokii, from Korea

Abstract

Wakinoichthys aokii was found from the Nagdong Subgroup of the Gyeongsang Group in a southern part of Korea. The species was first described from the Wakino Subgroup of the Kanmon Group from Kitakyushu, Japan in 1994. This is the first record from Korea other than the type locality. The existence of the species in both Japan and Korea suggests that the Nagdong Subgroup of the Gyeongsang Group and the Wakino Subgroup of the Kanmon Group are deposited at almost the same age.
