Jindong Formation

The Jindong Formation is a palaeontological formation located in Korea. It dates to the Cretaceous period.[1]

Archeological findings and sitings

The area has many dinosaur and bird tracks.[2] It contains Caririchnium kyoungsookimi, the first trackway of a quadrupedal ornithopod discovered in Korea.[3]

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. [4]
