YAMAGATA (Kyodo) A Japanese research team has discovered two geoglyphs on Peru's Nazca Plateau, which is designated as a UNESCO World Heritage site for its gigantic lines and geoglyphs.

The team, led by Masato Sakai, professor at Yamagata University's faculty of literature and social sciences, said Tuesday that the newly discovered geoglyphs appear to represent a human head and an animal.

In 2006, the same team announced the discovery of about 100 geoglyphs on the Nazca Plateau, many in the form of straight lines and triangles.
