Margaritifera Cf. Isfarensis (Chernishev) From The Amisan Formation, Nampo Group, Korea

This study describes Margaritifera cf. isfarensis (Chernishev) based on the previously-reported data and newly collected samples from the Amisan Formation distributed in the Dopung coal mine of Misan-myun, Boryung-city, Chungnam Province, Korea. The shape of this species is very similar to that of Margaritifera isfarensis (Chernishev) reported from the Jurassic strata of Russia and China. The fossil bivalve from the Amisan Formation consists of only one species belonging to Margaritifera, this genus is the first record in the Korean Mesozoic strata.
