A cave in Na Hang district in the northern province of Tuyen Quang is thought to have housed primitive humans during the Neolithic Era (7,000-8,000 years ago) after many tools made from stone and animal bone have recently been discovered.
Tuyen Quang Museum's director Quan Van Dung said that experts from the museum and the Vietnam Archaeology Institute discovered primitive human artifacts in the cave, which is known as Tham Choong Cave to the locals.
They include more than 1,000 stone objects, including tools for cutting, chopping and grinding. The tools were handmade with stones that had been retrieved from a riverbed.
The tools bore Hoa Binh cultural features (thousands of years ago and lasted till 2,000BC), he added.
At the site, archaeologists also found a narrow tool with a sharp point, which is assumed that it was likely used to stitch clothing that was made from tree bark.
