Saudi Arabia camel carvings dated to neolithic period

Stunning reliefs of camels in a rock formation in Saudi Arabia are far older than was first thought: they were carved more than 7,000 years ago, when the climate of Arabian Peninsula was markedly cooler and wetter than it is today. The revised estimate means that the camels are probably the world’s oldest surviving large-scale animal reliefs. Ancient builders seem to have restored the reliefs time and again as the animal features eroded, and the monuments might have retained their form and function for millennia.
