Buried in Sudan's desert, 280 vast stone circles reveal a vanished cattle-herding culture

Recent satellite remote sensing surveys have identified 280 stone structures spread across the Atbai desert in Sudan. Twenty of these structures were previously identified by fieldwork or informal surveys, but were not systematically studied as a regional tradition. Now, new research, published in the African Archaeological Review, takes a closer look at the purpose of these monuments and the unique, cattle-centered pastoralist culture behind them.
