The Jindong Formation is a geological formation located in South Korea. It dates to the Cenomanian stage of the Late Cretaceous, with a maximum depositional age of 99.9 ± 0.7 Ma.^[1]

Lithology[]

The formation is a thick layering of fine-grained, altered volcaniclastic sediments. Most of these sediments are ash-rich mudstone, siltstone, and very fine sandstone. There is also coarser sandstone, conglomerate, carbonates, and ash tuff. ^[2]

Paleontology[]

The area has many dinosaur and bird tracks.^[3] It contains Caririchnium kyoungsookimi, the first trackway of a quadrupedal ornithopod discovered in Korea.^[4]
