Human faces sculpted into stone up to 2,000 years ago have appeared on a rocky outcropping along the Amazon River since water levels dropped to record lows in the region's worst drought in more than a century.
In one specific location, there are polished rock grooves that are said to have been utilised long before European settlers arrived by natives as a means of sharpening their arrows and spears. The rocky spot is known to be Ponto das Lajes, surrounded by both the Rio Negro and Solimoes rivers. The place is on the north side of the Amazon River., Technology & Science News, Times Now
Human faces sculpted into stone up to 2,000 years ago have appeared on a rocky outcropping along the Amazon River since water levels dropped to record lows in the region's worst drought in more than a century. Some rock carvings had been sighted before but now there is a greater variety that will help researchers establish their origins, archaeologist Jaime de Santana Oliveira said on Monday. The rocky point is called Ponto das Lajes on the north shore of the Amazon near where the Rio Negro and Solimoes rivers join.
