Jindong Formation, Geological formation in Gyeongsangnam-do, South Korea.
Jindong Formation is a geological layer in South Korea made up of multiple strata of fine-grained sediment. The deposit contains mudstone, siltstone, and sandstone spread across the southern landscape.
This formation dates to the Cenomanian stage of the Late Cretaceous, about 99.9 million years ago. It developed through volcanic and sedimentary processes that unfolded over time.
The place draws researchers who study dinosaur and bird tracks preserved in the rock layers. These traces help scientists worldwide understand what creatures once roamed this region.
Access requires specialized permits and geological knowledge to understand the rock layers properly. It helps to coordinate with local authorities before planning a visit to the site.
The location holds the first known trackway of Hadrosauropodus kyoungsookimi, a four-legged dinosaur species. This creature was first identified in Korean territory, making it a significant discovery for science.
