Article Synopsis
- The discovery of 430 figurative Nazca geoglyphs took nearly a century, but an AI system recently identified 303 new figurative geoglyphs in just 6 months, almost doubling the total.
- The AI excels at detecting smaller relief-type geoglyphs, which are harder to see compared to larger line-type ones, providing a more comprehensive view of Nazca's ancient cultures.
- Analysis shows that relief-type geoglyphs mainly depict human-related motifs, while giant line-type geoglyphs primarily represent wild animals, suggesting different uses and meanings linked to individual versus community activities.
