Fardross Stream ASSI
It is extremely rare to find the boundary between five formations, so this is an exceptional exposure. The rocks, and the fossils they contain, indicate that they were laid down in a marine environment: as water depth and distance from land slowly increased through time, sand and mud deposition gave way to limestones. Fossils include colonial and solitary corals and brachiopods.
