Some 2,000 years ago, perhaps, ancient artists in the Arabian desert climbed tall rock outcrops and carved life-size camels into the stone.

Now, archaeologists exploring a site in northwest Saudi Arabia have discovered about a dozen of the humped sculptures. Although camel art has been found in other parts of the Arabian Peninsula, the newly uncovered engravings at the so-called “Camel Site” are stylistically unique.

The findings, which were reported Tuesday, could help provide insight into the history and development of rock art on the Arabian Peninsula.
