OKINAWA, JAPAN—CNN reports that a team of Japanese researchers led by Masaki Fujita of the Okinawa Prefectural Museum & Art Museum has found 23,000-year-old fish hooks made from sea snail shells in Sakitari Cave, located on the south side of the island of Okinawa. These fish hooks are older than hooks unearthed on Timor, which are thought to be at least 16,000 years old, and hooks found in Papua New Guinea, which have been dated to at least 18,000 years ago. The team also found evidence that early inhabitants of Okinawa cooked and ate frogs, birds, small mammals, eels, and perhaps even lobster. Human skeletal remains, beads, and an artifact that may be a grindstone have also been found in the cave. "We found fish and human bones that dated back some 30,000 to 35,000 years," Fujita said. "We don't know what kind of tools were used to catch these fish, but we're hoping to find some even older fishing tools."
