The Staffin Bay Formation is a geologic formation in Scotland that preserves fossils dating back to the Callovian stage of the Middle Jurassic. It composed of two members: the lower Upper Ostrea Member, which features of dark grey, fissile mudstone with a shelly limestone bed, along with laminated and rippled sandstone; and the upper Belemnite Sands Member, which consists of medium-grained calcareous sandstones and siltstones.
