The Bearreraig Sandstone Formation is a geological formation in Scotland. It preserves fossils dating back to the lower to middle parts of the Jurassic period (Toarcian–Bajocian). The remains of the proximal portion of a right ulna and radius of an indeterminate thyreophoran dinosaur are known from the formation. The ichthyosaur Dearcmhara is also known from the formation.
