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