The Arén Formation or Arén Sandstone (Catalan: Calcàries i gresos d’Areny)[1] is a geological formation in the Tremp-Graus Basin around Arén, Catalonia, Spain whose strata date back to the Late Cretaceous.[2] Dinosaur remains are among the fossils that have been recovered from the formation.[3] The formation dates to the Campanian to Maastrichtian and underlies the Tremp Group.
