Bearreraig Sandstone Formation
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).[1] The remains of the proximal portion of a right ulna and radius of an indeterminate thyreophoran dinosaur are known from the formation.[2]
