The giraffes of Dabous are life-size rock engravings of two giraffes in the Sahara from the Neolithic period. They are located on the sloping top of a sandstone block about 15 metres high and cannot be seen from the ground. The larger, male giraffe is 5.8 metres high from horns to hooves and is one of the largest rock engravings of its kind in the world. The female giraffe, which also carries a rope from its nostrils, measures 3.02 metres from head to tail tip. It is estimated to be between 7,000 and 10,000 years old. The giraffes are characterized by their great attention to detail and the preservation of proportions. - Niger - Aïr - 1999
