  Shendi Formation (Sudan) | |
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]
