Shendi Formation (Sudan) |
The Shendi Formation is a Late Cretaceous geologic formation of the Atbara-Shendi Basin in northern Sudan. Indeterminate theropod remains have been recovered from it. 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.
The formation overlies Precambrian basement and is overlain by the Hudi Chert. The total thickness of the formation amounts to 63 metres (207 ft).
