Jinju Formation

The Jinju Formation, also known as the Dongmyeong Formation in some literature is an Early Cretaceous geologic formation in South Korea. Lithology of the Jinju Formation could be distinguished from overlying and underlying formations by lack of red beds in the entire formation.

Fossil content
Plants Based on plant fossil records, the Jinju Flora is interpreted as a temperate intermontane savannah, due to mountain barriers blocking moisture. The assemblage was dominated by stress-tolerant, low-diversity flora adapted to the arid conditions or to localized waterlogged niches. Not only restricted to the Jinju Formation, but the entire floral diversity was relatively low throughout the entire Gyeongsang Supergroup. Palynofossil records also suggest the Jinju Formation was overall arid. Unnamed plant remains include 3 different types of unidentified ferns, at least 2 types of seed cones, a conifer pollen cone, detached conifer seed cone scales, a connate bractate organ of unknown affinity, and at least 9 different types of diaspores, including winged forms and likely fleshy forms.
