The Cercado Formation is a geologic group in Dominican Republic. The formation comprises siltstones, limestones, claystones, sandstones and conglomerates deposited in a shallow marine to reef environment. The Cercado Formation, unconformably overlying the Baitoa Formation, preserves bivalve, gastropod, decapod and coral fossils dating back to the Late Miocene to Early Pliocene period.[1]
