This 8,000 year-old giraffe rock carving in DaBous, Niger is considered one of the finest petroglyphs in the world. The giraffe has a leash on its nose implying some level of taming the animals. It was found relatively recently on the top of a granite hill by local Touaregs and dates to the Kiffian era of 7,000 - 9,000 years ago.
