8,000-year-old rock carvings in Arabia may be world's oldest megastructure blueprints

Stars and lines engraved in rocks on the Arabian Peninsula may represent nearby hunting traps, making these carvings the first scale-plan diagrams in human history, according to a new study that reveals humans' sophisticated understanding of space around 8,000 years ago.

Archaeologists first noticed these structures, known as desert kites, about 100 years ago, when aerial photography began taking off with airplanes. Kites are large areas of land bordered by low stone walls, sometimes with pits scattered on the inside near the edges. Found primarily in the Middle East and Central Asia, kites are thought to have functioned like pens or traps for animals. Hunters would herd animals, like gazelle, into the kite through a long, narrow passage, where the game would be unable to escape the walls or the pits, making them easier to kill. 

Because of their massive size — averaging close to the square footage of two football fields — kites cannot be seen in their entirety from the ground. But the advent of publicly available, high-resolution satellite images, such as those from Google Earth, has jump-started the study of desert kites in the past decade.

The recent discovery of architectural-like designs engraved in rocks in Jordan and Saudi Arabia has revealed how Neolithic humans may have planned these "mega-traps," according to a new study, published Wednesday (May 17) in the journal PLOS One.
