A Japanese university team researching Nazca Lines in Peru has discovered an additional 143 geoglyphs.
The Yamagata University research group led by Professor Masato Sakai announced the findings on Friday.
The team had been looking for Nazca Lines along narrow streets for three years until this past summer.
The lines depict humans, birds, and four-legged animals such as cats. The size ranges from five meters to as large as 100 meters. They are believed to have been created between 100 BC and 300 AD.
The researchers say they used artificial intelligence technology developed by an IT firm to analyze the data.
The approach led to a discovery of a human-like figure with three head decorations. They say it is the first case in which AI helped discover geoglyphs.
Sakai says they learned that AI is an efficient tool for this type of research. He says they want to create a Nazca Line distribution map and will analyze why these lines were created, while helping to preserve this cultural heritage.
