After two years of scanning the southern Pacific coast with drones, taking aerial photos, and conducting field surveys, researchers and archeologists have found 168 more geoglyphs.
According to National Geographic, there are over 800 straight lines, 300 geometric figures, and 70 animal and plant designs.
According to a statement released by Yamagata University, the carved figures are between 6 and 19 feet in length and include the figures of cats, snakes, killer whales, and alpacas. The lines are as long as 1200 feet.
The researchers from Yamagata University estimated the age of the geoglyphs to be between 100 BCE and 300CE.
Art News reported that Yamagata University researchers will work with IBM's T.J.Watson Research Centre to conduct a study on the distribution patterns of the latest necaglyphs.
The previous research conducted by the scholars revealed 142 additional Nazca formations, which included images of birds, monkeys, fish, and snakes.
According to a statement from Yamagata University, the creation of an archaeological park was a result of the discovery of 41geoglyphs in this area. A total of 77geoglyphs are known to be concentrated in this park.
Castillo told The Guardian that he thinks only 5% of the existing lines have been discovered.
Local guides believe the lines may be related to sources of water or maps of the region, while some archaeologists believe the shapes held a sacred purpose.
The exact methods used to create the lines, which are largely impossible to identify from the ground, are a mystery to researchers.
Yamagata University said that the black stone was removed to expose a white sandy surface below.
In pop culture, there are questions about whether the figures are alien visitors or landing strips for ancient astronauts because they are only recognizable from the air.
The UNESCO World Heritage site on the southern coast of Peru is facing threats from urban and economic developments according to a report.
According to Masato Sakai, a professor from Yamagata University who led the study, some geoglyphs are in danger of being destroyed due to the expansion of mining-related workshops.
Representatives of Yamagata University didn't reply immediately.
