Discovery of tools used by ancient humans in China 40,000 years ago

CAIRO – 9 March 2022: Archaeologists in China have discovered a hoard of intricate stone blades attributed to ancient humans who lived less than 100 miles (160 kilometers) west of modern Beijing.

It was indicated that these "advanced" tools were used about 40,000 years ago. Archaeologists also believe that these tools belonged to what is known as "Denisovans" or "Neanderthals" or both at the site. 

Archaeologists have not found any human remains at the Chiamabe site. They recovered fossils, including an iron-rich rock that could be used to make pigments.

In addition, scientists propose that the early hominins who inhabited Chiamabe probably used fire to be able to use blade-like stone tools to cook the meat they hunted.

The scientists found 382 artifacts at the site. Two specific pieces of ocher with different mineral compositions, and a limestone slab with distinct smooth areas excited archaeologists the most. 

The researchers determined that the different types of ocher were brought and processed through crushing and scraping to produce powders of different colors and sizes.
