Located about 400 km south of Lima, the mysterious lines and geoglyphs of the Nazca Desert have fascinated scientists for nearly a century, and been designated a UNESCO World Heritage Site to ensure their protection. Researchers from Japan's Yamagata University have used advanced technology, including artificial intelligence, to discover a whopping 143 never-before documented geoglyphs along southern Peru's Nazca plateau, NHK has reported. The geoglyphs, compiled over the course of over three years through the careful examination of the faint outlines of the patterns, were revealed at a presentation on Friday. The 143 new images, ranging from just five meters to 100 meters in size, include a mysterious humanoid, a square-headed creature, along with various animals, including what appear to be cats, massive two-headed snakes, fish and even what looks like a dinosaur, with the newly-found geoglyphs said to have been created between 100 BC and 300 AD.
