Jinju Formation

The Jinju Formation is an Early Cretaceous geologic formation in South Korea.[1] Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2] It has been dated to the Albian stage.[3] It predominantly consists of black shale, interbedded with sandstone packets, deposited in a fluvial-lacustrine setting.
