Dinosaur remains are among the fossils that have been recovered from the formation.

The approximately 70 m 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.

Depositional Environment

The Escucha Formation represents syn-rift depositional environment, deposited in siliciclastic carbonate platforms, coastal siliciclastic environments and other offshore settings. In the basal part of the formation, cobble to boulder-sized dropstones of glacial origin have been identified, representing long-distance iceberg rafting from Arctic sources.

Fossil content

The Escucha Formation has provided the following fossils, among others:
