Includes fossils?Y
Lithology description: "throughout a ~5 m thick, lens-shaped deposit. There is no single fossiliferous layer...occurring in an olive-coloured silty mudstone, with occasional lenses of sand...It overlies a sequence of alter- nating grey mudstones and white-tan channel sandstones, which suggests that it also represents an overbank deposit."
