Escucha Formation
The Escucha Formation is a geological formation in La Rioja and Teruel provinces of northeastern Spain whose strata date back to the late Aptian to middle Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. The approximately thick formation underlies the Utrillas Formation and overlies Castrillo de la Reina, Benassal & Oliete Formations. The Escucha Formation comprises siltstones, mudstones, sandstones, coal, siltstones and amber, in which several fossil insects were found. The formation was deposited in a variety of continental to paralic (deltaic) environments.
