Arén Formation

April 11, 2024

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.

Paleontological sites of interest edit

-Les Serretes. It is a place in Vilamitjana municipality known by the finding of an important paleontological site. In this site there have found dinosaur remains that belongs to the Second biggest hadrosaur found in Spain, and the biggest of Catalonia. Also there have been found two carnívor dinosaur tooth that belongs to two new dinosaur species morphotypes.[9][10]
