Prehistoric rock art in the remote valley of Teimareh in central Iran. The valley is full of ancient petroglyphs, belong to 4500 to 17000 years ago. With over 30,000 engraved images, the valley is one of the world's most important petroglyph sites, still largely undiscovered. Here there are many petroglyph pictures, representing animals and hunting scenes. Few animals here are clearly those which are no longer living on this planet.
