Archaeologists recently identified 260 enclosure burials in Sudan's Atbai Desert that date back as far as 4000 B.C.E. and hold the remains of humans and livestock from an unknown nomadic culture.

In the far reaches of the eastern Sahara, archaeologists have uncovered hundreds of prehistoric burials that suggest an unknown culture once thrived in what’s now Sudan — long before the ancient Egyptians built their monumental pyramids just to the north.
A recent study of the Atbai Desert used satellite and aerial imagery to identify 260 previously-unseen burials between the Nile River and the Red Sea. While a few similar sites have been excavated previously, the discovery of these additional mass graves is rewriting the history of northern Africa in the era before the pharaohs.
Uncovering The Prehistoric Enclosure Burials In The Atbai Desert
In a study published in the African Archaeological Review, archaeologists from Macquarie University, France’s History and Sources of Ancient Worlds laboratory, and the Polish Academy of Sciences carried out an extensive survey of satellite and aerial imagery in the Atbai Desert of eastern Sudan.
As the study authors wrote in a statement released by Macquarie University, “Our team… wanted to tell the story of this desert region between the Nile and the Red Sea, without having to excavate.”

Across roughly 600 miles of desert, the researchers identified 260 burials enclosed by round or oval walls, some stretching 260 feet in diameter. Just 20 similar sites were previously known to exist, such as Wadi Khashab, Wadi el-Ku, and Bir Asele. Prior excavations revealed human remains within these enclosures, as well as the bones of cattle, sheep, and goats.
The presence of the animals suggests that the enclosures were built by a nomadic culture that raised livestock across the region. Analysis of artifacts found at the previously-known sites dates them to between 4000 B.C.E. and 3000 B.C.E. — centuries before the first Egyptian pyramid was constructed.
So, who were these people? And what can their burials tell us about their culture?
The Prehistoric Nomadic Herders Of Northeastern Africa
While none of the recently discovered enclosure burials have been excavated yet, sites like Wadi Khashab and Bir Asele give researchers a good idea of what these newly-found graves likely contain. The burials there sometimes featured a central figure — perhaps a chief or key member of the community — surrounded by additional remains in a seemingly meaningful pattern. This implies that the nomadic society had some sort of social structure.
“For archaeologists,” the study authors wrote in the statement, “this is important data for discerning class and hierarchy in prehistoric societies.”
Between 4000 B.C.E. and 3000 B.C.E., northern Africa was undergoing a change in climate known as the “African Humid Period.” The Sahara — which was once much greener than it is today — was beginning to dry up, making it difficult to maintain large herds of livestock.
As such, nomadic herders may have been buried with their animals as a display of status. The researchers likened it to “showing off an expensive and rare possession — a prehistoric nomad’s equivalent to having a Ferrari.”
Indeed, the vast majority of these enclosure burials are located near former water sources, such as rock pools and ancient lakebeds, suggesting the nomads had moved into areas that could sustain their herds as vegetation grew scarce.

It also seems that nomads returned to these enclosures for thousands of years, reusing them as burial plots well into the first millennium B.C.E. But the original graves stand as some of the earliest examples of monuments honoring deceased leaders. The first Egyptian pyramid — the Pyramid of Djoser — wasn’t built until around 2670 B.C.E., and Sudan’s Nubian pyramids didn’t appear until the eighth century B.C.E.
But these emblems of a prehistoric culture are under threat. Unregulated gold mining in the deserts of Sudan has brought damaging heavy machinery and looters to the region, and the burials may be destroyed before archaeologists have a chance to study them further and learn more about the nomadic societies that roamed Sudan 6,000 years ago.
“Our discovery reshapes the story of the Sahara deserts and the prehistory of the Nile,” wrote the study’s authors. “They provide a prologue for the monumentalism of the kingdoms of Egypt and Nubia, and an image of this region as more than pharaohs, pyramids, and temples.”
