The Newmarracarra Limestone is a Bajocian geologic formation, in Western Australia. It consists of yellow grey sandy or clayey limestone, which occasionally grades into calcareous sandstone.[1] Fossils of the Rhynchonellida in the family Wellerellidae, Cirpa fromontae were reported from the formation.[2]
