Revealing techniques for manufacturing ancient weapons from 77,000 years ago

Stone weapons in the cave of South Africa have been announced by scientists as human evidence has mastered the technique of creating weapons about 77,000 years ago.

The researchers say the discovery is the first evidence that the earliest method of making stone is considered "rust-pressing technology". This technique is performed using a brushed bone tool that removes small pieces of steel from the grindstone.

Research results of Professor Veerle Rots, from the Fund for Scientific Research at the University of Liège, Belgium, said: "In contrast to other stone grinding techniques, the patented technology helps people increase the aesthetics and dependence. Correction of sharp edges of weapons ".

Researchers unearthed ancient stone weapons from ancient sediments in Sibudu cave in South Africa. These weapons are anticipated from medieval times (about 300,000 years ago), a time known for technological advances. During this period, hunter groups began using heat press methods to produce stone weapons.

The team noted that archaeologists also found evidence of the patented technology applied by humans in many different places. Earlier, they also discovered stone weapons that lasted more than 75,000 years in caves in Blombos, South Africa.

However, no one can accurately guess the time when humans invented and applied this technique. Recent findings are a step forward for scientists to find out when the answer to how to develop weapons is developed.

After weapons were excavated, scientists analyzed them by determining organic residues and wear over time. Some weapons have two sides, which can be created by applying force on both sides of the stone. In some cases, the stone is covered with a wooden or plastic handle and used as a spear, a label or an arrow.

Rots said that of the 25 stone weapons discovered in the cave, 14 weapons were identified with traces of animal blood, feathers and bones. Most likely, these weapons were used for hunting purposes.

"This may be evidence of the technology of hunting dedicated weapons in South Africa from 77,000 years ago , " Rots said.
