Teardrop-shaped stone hand axes found in 1978 at Jeongok-ri, near the DMZ, among the first such finds in East Asia.

In 1978 Greg Bowen, a US Air Force airman who had studied archaeology, spotted worked stones by the Hantan River at Jeongok-ri (전곡리), Yeoncheon County. Excavations found two-sided, teardrop-shaped hand axes of the Acheulean type, a design long thought absent from East Asia. The tools lie in sediments above basalt from ancient lava flows. Age estimates range widely, from about 300,000 to 40,000 years ago, because those layers are hard to date.
Why it matters
They undercut the 'Movius Line', a 1940s theory that East Asia lacked hand axes and lagged technologically behind Africa and Europe.
How we know
Excavations since 1979 have yielded thousands of stone tools in place; dating uses the underlying basalt and several lab methods. The finds are shown at the Jeongok Prehistory Museum.
Still debated
Their true age, and whether they reflect contact with Western toolmaking traditions or independent local invention, is still argued.
Connections (2)
▸Jeongok-ri hand axes are evidence of Paleolithic KoreaMostly agreed
The connection
The Jeongok-ri hand axes are among the clearest proof that toolmakers lived on the peninsula deep in the Old Stone Age. Their two-sided Acheulean form ties early Korea to a tool tradition found from Africa to Europe, not a separate, simpler East Asian world.
When and how
Banks of the Hantan River, Yeoncheon County, Gyeonggi Province; found by US airman Greg Bowen in 1978 and excavated by Korean archaeologists from 1979.
How sure are we?
Thousands of stone tools excavated in place within soil layers above ancient basalt lava flows.
Debates and open questions
How old the oldest tools are, from roughly 300,000 to well under 100,000 years, and who made them are still argued.
▸Jeongok-ri hand axes long predate the bronze tools of Mumun (plain pottery) periodMostly agreed
The connection
The contrast spans almost all of Korean prehistory. Jeongok-ri's chipped stone hand axes are tens or hundreds of thousands of years older than the cast bronze daggers and polished stone tools of the Mumun period. Between them came pottery, settled villages and farming.
When and how
Jeongok-ri tools roughly 300,000–40,000 years ago; Mumun bronzes from about 1000 BC; both found in central Korea.
How sure are we?
Geological dating of the Jeongok-ri layers and radiocarbon dating of Mumun sites put them far apart in time.
Debates and open questions
The size of the gap depends on Jeongok-ri's disputed age.
