MEXICO CITY, MEXICO—An atlatl and two wooden darts have been recovered from a remote room in central Mexico’s Cueva del Tesoro, or Treasure Cave, according to a Newsweek report. Some modified logs found in the room may have also been used as tools. The hunting weapons, radiocarbon dated to 1,900 years ago, were discovered by members of a cavers’ association who notified officials at Mexico’s National Institute of Anthropology and History. Archaeologist Carlos Viramontes said that hunter-gatherers lived in the area as early as 9,000 years ago, and survived for about 200 years after the arrival of Europeans. No other artifacts of this age have been recovered from the cave. Further investigations may provide additional clues, however, Viramontes explained.
