The Mugher Mudstone is a geologic formation located in Ethiopia. It dates to the Tithonian stage of the Late Jurassic. The lithology consists of gypsum, dolomite and shale alternations at the base, overlain by mudstone intercalated with fine to medium grained sandstone.[1]
Indeterminate dromaeosaurid teeth are known from the formation.[2] Many other remains have been uncovered also, including indeterminate ornithopods and allosauroids.[3] The tooth of a macronarian sauropod is known from the formation[4]
