12,000 years ago, humans carved giant camels into Saudi rocks. Scientists think they marked something vital

There was a time when travelling across Arabia was not just difficult, it could be a matter of survival. There were no roads, no maps and no permanent water supply. For people moving through what is now northern Saudi Arabia, knowing where water could be found may have determined whether they could safely reach the next part of their journey.

Now, scientists studying giant animal carvings in the Arabian Desert believe some of those ancient people may have left behind something like a map, not on paper, but carved directly into stone.

The findings were published in Nature Communications on September 30, 2025, by an international research team led by archaeologist Maria Guagnin. Researchers have documented 176 rock engravings across 62 panels in three areas south of Saudi Arabia's Nefud Desert. Of these, 130 depict life sized animals, including around 90 camels, along with ibex, wild donkeys, gazelles and an aurochs, an extinct relative of modern cattle.


Some of the figures are enormous. National Geographic reported that some of the engravings were more than six feet tall and that the findings pushed back evidence of human occupation in the region. Individual animals can measure up to about 3 metres in length and more than 2 metres in height.

Science News reported that the life-sized engravings at Jebel Misma date to between 12,800 and 11,400 years ago, offering evidence of early human presence in the Nefud region, making the carvings part of one of the oldest dated monumental rock-art traditions known from Arabia.

A desert people learned to read

The Nefud Desert is extremely dry today, but around 12,000 years ago, parts of northern Arabia looked very different. Seasonal water bodies appeared across the landscape, giving human groups places to stop before moving on when conditions changed.

For people living on the move, knowing where water could be found was crucial. A lake or shallow basin might not last through the year, so remembering the landscape and knowing when to return would have been part of everyday life.

Researchers found evidence of ancient shallow basins, known as playas, near the areas where the rock art was discovered. Archaeological evidence also shows that people were using these landscapes during a period when Arabia was becoming increasingly dry.

Many of the large animal figures were found close to ancient water sources and natural routes through the landscape. Researchers believe some of the carvings may have helped people recognise important places or routes, and may even have indicated areas associated with access or territory.

For someone crossing a vast stretch of desert, a large animal carved into a rock face could have made a particular location easier to recognise. Whether that was the original purpose of every carving is impossible to know, but the possibility gives the artwork a surprisingly practical dimension.

It was more than an art

National Geographic also noted that some engravings were made in difficult to reach places on cliff faces, and researchers could not confirm whether the stone tools found nearby were used to create the carvings.

Some were made on steep, difficult-to-reach sections of rock, with artists apparently working from narrow ledges. In some places, they may not even have had enough room to step back and see the entire animal while carving it.

Stone tools were also found in archaeological layers associated with the sites. One tool came from sediment dating to around 12,000 years ago, although researchers cannot prove that it was used to create the nearby engravings.

The animals were depicted with considerable attention to detail. Many of the camel figures appear to be males in rut, showing the swollen neck associated with the mating season. That suggests the artists were representing animals they knew well, rather than simply carving generic shapes into the rock.

Some panels contain newer engravings over older ones, suggesting that different groups may have returned to the same locations over generations. The landscape itself was becoming a record of the people who passed through it.

A message that survived for thousands of years

Researchers cannot say that every camel was meant as a marker. Some of the carvings may have carried ritual or symbolic meanings that are now impossible to understand.

But the sites offer a rare glimpse into how people experienced this landscape thousands of years ago. They returned to the same places, added new images over older ones and left behind scenes that outlived the communities that created them.

There were no written records of their journeys. Instead, their stories and perhaps some of their knowledge remain etched into the rocks.

And 12,000 years later, those giant camels are still standing where they were carved. a reminder that even in a landscape that seems empty today, people once knew exactly where they were going.
