MATSUE--Twenty stone tools believed to be the oldest discovered in the nation have been excavated from a mid-Paleolithic period geological layer, dating back 120,000 years, at an archeological site in Izumo, Shimane Prefecture, researchers said Tuesday.
According to a team of experts, led by Prof. Kazuto Matsufuji of Doshisha University, that has researched the Sunabara remains, the tools are tens of thousands years older than any previously discovered.
The existence of stone tools dating back to the early and mid-Paleolithic period in this country was thrown into question in 2000, when a former deputy director of the disbanded Tohoku Paleolithic Institute buried stone tools and later recovered them, claiming they were unearthed from 700,000-year-old archeological remains in Kurihara, Miyagi Prefecture, and other sites.
Archeologists say the latest discovery could change the way the era is studied.
The tools are between 5.2 centimeters and 1.5 centimeters long and made of quartz or rhyolite. Their surfaces indicate that they were chipped into shape.
The excavation site is located on a slope in a hilly area.
In August, Toshiro Naruse, a professor emeritus of Hyogo University of Teacher Education and a physical geography expert, discovered a knife-shaped stone tool at the site. Naruse asked Matsufuji and other researchers to research the area, leading to 19 other stone tools being discovered there.
The age of the tools was determined by examining the volcanic ash layer just above the layer from which these tools were excavated.
Summary:
研究者たちは火曜日、島根県の出雲で１２万年前の日本最古の２０個の石器が見つかったと発表した。
その石器は5.2ｃｍと1.5ｃｍの長さで、石英または流紋岩でできている。
それらの表面は、石のかけらだということを示している。
発見場所は傾斜のある丘である。
8月に、兵庫教育大学の名誉教授である成瀬敏郎がナイフ型の石器をそこで発見した。成瀬さんは松藤さんや他の研究者たちにそこの研究を頼み、その場所で19個の他の石器が発見された。
What I find interesting:
今から12万年も前の石器を発見することができて、
その上発見された石器がいつの時代のものなのか特定できるなんて、現代の科学技術はすごいと思いました。
これから先、もっと昔の石器が発見されたり、研究が進んで、過去のことがより詳しくわかるようになるといいなと思いました。
