Stone tools made of obsidian limestone have been found In a cave in Trabzon, Western Armenia. They are supposed to date back to BCE 11,000 years ago. The study showed that the stones are cutting tools belonging to the first group of people living in the region. Archaeologists, who have made important discoveries in human history in the area, aim to excavate more finds in the cave, dating back to the famous Portasar era.

Seven of the obsidian-silica stone tools were sent to McMaster University in Canada for analysis of origin.

It turned out that two of the stones used as “cutting tools” have Transcaucasian (Georgian-Armenian) origin.

It is believed that the stone was brought from abroad as there is no obsidian resource in Trabzon.
