A New Lanternfish (Myctophiformes, Myctophidae) from the Middle Miocene Duho Formation, South Korea
A new fossil lanternfish of the extant genus Stenobrachius, †S. sangsunii sp. nov., is described from the Middle Miocene deposits of the Duho Formation, South Korea. This is the second fossil species of the genus after the Miocene †S. salnikovi from Karaginsky Island in the Bering Sea. The new speci...
