YAMAGATA, JAPAN—A team from Yamagata University has found an additional 24 images etched into the dust in urban areas of Nazca, Peru, using a 3-D scanner. The geoglyphs, many of which are heavily eroded, date from 400 to 200 B.C., and are thought to be older than other Nazca Line images such as the hummingbird. Most of the newly found drawings depict llamas. “There are no other areas concentrated with this many examples. Yet with both urban areas and farmland encroaching on the drawings, they are under the threat of being destroyed without being recognized as geoglyphs,” Masato Sakai of Yamagata University told The Asahi Shimbun.
