A paleontology research group at the Geology Faculty of Kim Il Sung University has intensified the study to newly fix the position of the fossil reserve in Paektho-dong. In the course, the group unearthed a cretaceous fossil bird with skull, toe bones, eleven primary quills and small barbs in the area. Researchers proved scientifically that it was a fossil bird suitable to flying.

The group also discovered one piece of fossil tooth of dinosaur, one fossil primitive mammal, 60-odd pieces of fossil fish, more than 210 entomolites, 40-odd pieces of fossil shellfish and mud-snail and other fossils rare to be seen in the world.

With those fossils, the research group proved in a scientific way that the Paektho-dong area is a place where all Mesozoic vertebrates in the country appeared. And it newly set the Sinuiju biota representing the Mesozoic era and confirmed again the fossil reserve in Paektho-dong.

The above-said discovery shows that Korea is a native place of mankind as well as a cradle of birds.

At the state scientific and technological review, it was appreciated that the result of study on paleontology conducted in the Paektho-dong area is of great significance in deepening the researches into Cretaceous biota of the Mesozoic era in the country.
