Credit: Yamagata University/ReutersResearchers discover over 100 new ancient designs in Peru's Nazca linesMore than a hundred new designs discovered in and around Peru's ancient Nazca plain and surrounding areas could bring new information to light about the mysterious pre-Columbian artworks that have intrigued scientists and visitors for decades.The geoglyphs, huge figures carved into the South American desert, date back more than 2,000 years and represent humans, cats, snakes, killer whales, birds and native camalids — animals such as llamas, guanacos and alpacas.Jorge Olano, head archaeologist for the Nazca Lines research program, said the new figures averaged between two and six meters (6.56 to 19.7 feet) in length.This month's findings, however, are smaller and can be seen from the ground, Masato Sakai, a professor from Yamagata University who led the study, told Reuters.Yamagata University said the research will be used in artificial intelligence-based surveys to help inform the lines' preservation."
