The Shendi Formation is a Late Cretaceous geologic formation of the Atbara-Shendi Basin in northern Sudan.[1] Indeterminate theropod remains have been recovered from it.[2] As well as those of the dyrosaurid Hyposaurus. It consists of a lower unit of fine grained meandering channel sediments, separated by an erosive contact with overlying meandering to braided river channel sandstones.[3]
The formation overlies Precambrian basement and is overlain by the Hudi Chert.[1] The total thickness of the formation amounts to 63 metres (207 ft).[4]
