The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous (Barremian stage). The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from 300 to 800 metres (980 to 2,620 ft), were deposited in fluvial, deltaic and lacustrine environments. Dinosaur remains have been recovered from the formation.
