Natural Monument—Archaeopteryx Coreanicus Fossil.

The fossil of Archaeopteryx Coreanicus was unearthed on March 10, Juche 78 (1989) in the argillaceous siltstone layer piled up between the Jurassic period and the early Creataceous period in the Mesozoic age. The layer is located in Paektho-dong, Sinuiju City, North Phyongan Province.

The fossil, the first of its kind in the DPRK, consists of a brainpan, pterygoid with sharp hooked claws, neck bone and quill.

This proves that the bird developed from the reptiles.

Also discovered there were the fossils of fishes, insects and gastropods，dinosaur’s teeth, pterodactyl, plants, and various species of spore and pollen. They are of great significance in studying biodiversity and ecological environment.

The fossil of Archaeopteryx Coreanicus is now preserved in the Natural History Museum of Kim Il Sung University as a natural monument.
