Jinju Formation (South Korea)

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, with sandstone packets, deposited in a fluvial-lacustrine setting.

A diverse spider fauna is known from the formation, including indeterminate mygalomorphs and palpimanoids as well as two species of lagonomegopid belonging to the genera and .^[4] Other compression fossils known from the formation include a species of the zhangsolvid fly and elaterid beetle .
