Artificial intelligence has helped researchers to uncover hundreds of ancient land artworks in Peru.
The mysterious pre-Hispanic figures, known as geoglyphs, are motifs etched into the ground via the movement of stones or gravel. Such figures have been found across the Nazca desert region in southern Peru on a high, arid plateau.
The geoglyphs provide archaeologists with a unique window into the cultures and beliefs of the ancient people who created them, with the earliest examples dating back more than 2,000 years. The geoglyphs were designated as a UNESCO World Heritage Site in 1994.
Field surveys that began in the 1940s and continue to the present day identified around 430 figurative geoglyphs depicting various figures, including animal and humanoid motifs, over a period of around a century.
