New | World’s earliest fishhook found in Okinawa, Japan
Fishhook made up of sea snail shell

A 23,000-year-old fishhook that is considered to be one of the world’s earliest has been excavated in Okinawa, southwestern Japan, local researchers said Monday.
The 1.4-centimeter-long, crescent-shaped hook made of sea snail shell represents a rare discovery of fishing gear from the Paleolithic era, or the Old Stone Age, according to the Okinawa Prefectural Museum & Art Museum.
“It’s a precious material illustrating a new aspect of the Paleolithic period during which we had thought people mainly hunted on land,” the museum said.
The hook was unearthed in 2012 during excavation at the Sakitari Cave site in Nanjo, Okinawa Prefecture.

Researchers have identified its age by radiocarbon dating of charcoal contained in the layer from which the hook was found.
