Remarkably, the AI was able to identify 303 new prominent geographical figures in just half a year, which is almost double the catalog of known figures as mentioned in the study published on PNAS. These newly discovered artworks mainly show human figures, pets and severed heads. This offers profound insights into the ritual life and daily life of the Nazca people who created it more than 2,000 years ago.
303 hidden geoglyphs identified by artificial intelligence and high-tech surveys in Peru
Nazca research is particularly challenging because of the vastness of the desert and how small geoglyphs, such as those marking the terrain, erode over time. Scientists have made significant progress using deep learning AI to analyze existing data. This allowed them to review high-resolution satellite images with remarkable accuracy; The AI has identified potential locations at speeds 20 times faster than human experts can achieve.
It efficiently filtered out irrelevant data and sharpened patterns that indicated man-made structures. As a result, this combination of technology and historical study turned what would have taken a century into a completed work in just one season.
Why size matters in Nazca
Archaeologists have classified these figures into two main categories. One of them includes the famous geoglyphs, which are huge images that often represent birds or whales.
The other category is smaller geomorphs. Interestingly, most of the 303 recent finds fall into the relief category. They are made by removing dark stones to expose light sand in small, detailed designs, as described in research published in PNAS.
These are usually found along ancient footpaths rather than on wide open plains. This suggests that they were intended for travelers passing by on foot, and not for viewing from above.
Why do the new characters have “human” themes?
The 303 geographies present images that differ from what we have seen before. Large linear figures usually depict animals, but these smaller relief sculptures tend toward “human-related” themes. Among them, researchers discovered numerous images showing people dressed in ceremonial clothing, domesticated llamas, and even gruesome images with severed heads. This difference indicates a different social role for these prominent geographical forms.
It appears that they may have been used for rituals or to mark territorial boundaries within local communities.
The role of artificial intelligence in preserving the environment and mitigating its impacts in urban areas
According to the study published on PNAS, artificial intelligence plays a crucial role in the preservation of UNESCO World Heritage sites, offering more than just the thrill of discovery. The Nazca Pampa faces threats such as urban sprawl, mining activities, and environmental changes. Researchers can quickly map and document 303 new sites, providing the Peruvian government with precise coordinates for establishing conservation areas.
This digital record remains available for future generations even if the physical locations deteriorate.
